Metabolism: how Randox is helping to diagnose metabolic conditions
Many people talk about their metabolism as if it is a muscle or organ they can somehow control. In reality, your metabolism refers to a series of chemical processes in each cell that turn the calories you eat into fuel to keep you alive.
Metabolism is the biochemical process of combining nutrients with oxygen to release the energy our bodies need to function. Your resting metabolic rate (RMR) is the number of calories your body burns to maintain vital body functions such as heart rate, brain function and breathing. RMR accounts for up to 75 percent of the calories you burn each day. Knowledge of your individual RMR is a critical piece of information to appropriately establish daily calorie needs.
The body’s major organs — the brain, liver, kidneys, and heart — account for about half of the energy burned at rest, while fat, the digestive system, and especially the body’s muscles account for the rest.
Did you know?
Approximately 20-25% of the world’s adult population have metabolic syndrome?
A common misconception surrounding metabolic health is that it refers solely to your weight, and if you are overweight you are considered to be unhealthy. But in actual fact this may not be entirely true. Good metabolism means that your body is in good overall health, which doesn’t account for just your weight! Common metabolic disorders include genetic metabolic disorders, diabetes and metabolic syndrome. Understanding and testing to see how well your metabolism is functioning is key to ensuring long lasting health.
There are a number of genetic metabolic disorders caused by mutations of single genes. Examples of common disordersinclude Gaucher’s disease, hemochromatosis and cystic fibrosis. Gaucher’s disease is a genetic disorder that affects the body’s ability to break down fat that can accumulate in the liver/spleen and bone marrow. Hemochromatosis is a condition that is caused by the over-absorption and build-up of iron while cystic fibrosis is a metabolic disorder that appears as a result of a build-up of mucus in lungs/liver and intestines. Each of these metabolic disorders affect certain organs from functioning properly and therefore your overall healthiness.
Type 2 diabetes is one of the most common types of metabolic disorders in the world that is expected to affect 592 million people by 2035. It is characterised by high blood sugar, insulin resistance or a lack of insulin being produced by the pancreas. Insulin resistance occurs when the body isn’t able to use insulin the right way which increases blood glucose levels. Insulin is needed for cells to take in glucose (sugar) from the bloodstream and convert it into energy. Over time this lack of insulin can damage the organs in your body.
Metabolic syndrome (also known as syndrome X, Reaven’s syndrome, and CHAOS) is not a disease but a collection of risk factors that affect your health; these include high blood pressure, high blood sugar/cholesterol and abdominal fat. Left untreated, these risk factors, together, can lead to long term serious problems including an increased risk of heart disease, stroke and developing type 2 diabetes.
Can you improve your metabolic health?
Yes! The good news is that if you discover that your metabolic health is not up to scratch you can improve it through a combination of diet, exercise and lifestyle adjustments such as:
- 30 minutes of moderate to intense exercise 5-7 times a week
- Low-dose aspirin to reduce your risk of stroke or heart attack
- Quit smoking
- Medication for blood pressure/cholesterol/ blood sugar
- Limit alcohol intake
- Eat a healthy balanced diet

From April 23rd to April 29th we are celebrating Medical Laboratory Professionals Week! This is a week dedicated to raising awareness for those who work in a laboratory & the hard work that goes unnoticed every day in laboratories around the world.
Have you ever wondered what happens between submitting your patient sample and receiving your results? Have you ever wondered who conducts the detailed laboratory testing for your annual check-up such as cholesterol and glucose levels? Or who analyses these results? The answer, a Medical Laboratory Professional (MLP). MLP’s provide up to 70% of the medical laboratory results for physicians and others to make informed decisions about a patient’s diagnosis and aftercare treatment plan. The work that laboratory professionals do each and every day is integral to providing excellent patient care. They perform and interpret billions of laboratory tests every year.
Providing accurate and reliable test results is of the utmost importance for laboratory professionals and also for us at Randox. With a passion for Quality Control, and with more than 30 years’ experience developing Laboratory QC for the in vitro diagnostics market, we believe in producing high quality material designed to streamline procedures, whilst reducing costs in laboratories of all sizes and budgets. These qualities have been reflected in our Acusera true third party quality controls, Acusera 24.7 interlaboratory data management software, Acusera Verify Calibration Verification material and RIQAS, the largest international EQA scheme.
Randox Quality Control would like to take this opportunity to thank all the laboratory professionals around the world and especially our own laboratory staff – you truly are the “Unsung Heroes of Healthcare”.
“In Vitro Diagnostics (IVD) Quality Controls Market” recently published by Markets and Markets has highlighted an overall significant growth within the Quality Control Market. Further growth is anticipated in the coming years with the Markets and Markets report estimating that the IVD QC market will be worth $979 million.
One area that is currently experiencing growth within this sector is the EQA segment, which Markets and Markets estimates to command a 6.6% share of the overall IVD market. The report is crediting growth within this segment to you, the customer, stating “…various end users or customers of IVD quality control products mostly prefer external support to run their quality control activities. For this, market players are largely focusing on providing external quality assurance (EQA) support”. As such companies such as Randox are being approached to provide EQA for a range of small, independent laboratories and large laboratory chains alike.
What other factors have contributed to this growth?
The adoption of ISO15189 and other similar standards is becoming mandatory in many countries, as discussed in a previous blog post. Accreditation highlights the accuracy and reliability of the patient results being released. ISO15189 states that “The laboratory shall participate in interlaboratory comparisons such as those organised by external quality assessment or proficiency testing schemes”. Therefore laboratory managers are employing EQA programmes in their laboratory to meet such requirements. EQA also enables laboratories to meet other accreditation requirements such as peer comparison and clinically relevant testing.
Selecting the right EQA for you
When selecting the right EQA scheme for your laboratory there are a number of considerations to be made; sample frequency, peer group numbers, report format, report turnaround and so on. According to a survey conducted by Randox Quality Control 55% of respondents listed sample frequency as the most important feature to be considered when selecting an EQA scheme. Sample frequency is an ongoing debate regarding EQA. However, schemes with frequent reporting will allow you to easily pinpoint when an error occurred and implement corrective actions with minimal disruption. Also making the top three key factors in this survey were; quality samples and peer group numbers.
What can Randox Quality Control offer?
As the largest international EQA scheme available on the market RIQAS offers laboratories around the world assurance that the results they are releasing are accurate and reliable. With more than 40,000 participant in 124 countries and 32 flexible programmes we are certain that the external support we offer for your quality control activities will provide you with the upmost confidence in your laboratory’s performance.

A laboratory running a competitors 3rd party Microalbumin QC noticed shifts in their QC values whenever they changed reagent batch.
They tested two levels of quality control over three different batches of reagent the results can be seen in the table below.
|Competitor Control – Microalbumin|
As can be seen from the findings above, Microalbumin results shifted significantly each time they changed reagent batch. This was the case for both the level one and level two control however when the lab tested the same set of patient samples across the three reagent batches results were consistent and did not show the same shifts.
The laboratory decided to contact Randox and ask about our Microalbumin controls. They were concerned about the shifts seen with their current supplier and highlighted the fact they were no longer confident in the results they were releasing. This led to them trialling the Randox liquid ready-to-use Microalbumin control with the same three reagent batches they tested previously.
Having tested two levels of the Randox quality control over the same three reagent batches the laboratory reported to us that their results were back on track and they were delighted with the outcome! The results of the Randox control can be seen in the table below.
|Randox Control – Microalbumin|
The difference seen with the Randox control across the three reagent batches was much smaller than that of their previous control and was in line with the changes seen with their patient samples.
This case study highlights the commutability of the Randox QC range. By using a control with a matrix that reacts to the test system in the same manner as the patient sample the laboratory was confident in the patient test results produced and were able to meet ISO 15189:2012 requirements.
Today, June 27th, sees the beginning of one of the four tennis majors – Wimbledon. Basking in the summer sun while lying on ‘Henman Hill’, this yearly tournament attracts spectators from all over the globe who want to watch the world’s best tennis players ply their skills on the revered centre court over the course of a two week period. But what exactly is the most important skill a tennis player can utilise? Well, many players have different strengths but the one skill that all of them must possess is the ability to serve – and accurately.
The ability to serve is vitally important as it allows the point to begin, serving accurately however allows the player to set the pace and ensure they are on the front foot. By making sure they serve more accurately, the player can be confident in their ability to win the point and the match.
Just like tennis, laboratories will aim to be accurate when ‘serving’ up their test results. Achieving accurate test results is what every lab strives for. With patient results on the line it is important for labs to use QC material that will assist them in obtaining the correct results, therefore keeping them clear of causing a ‘racquet’.
Randox Acusera is world renowned for delivering unbiased performance assessment. Our range of true third party controls are manufactured to the highest standard ensuring commutable samples that react to the test system in the same manner as a patient sample, ultimately allowing labs to be confident in the results they produce. Much like the serve in tennis that needs to fall within a target area, QC results should be as close as possible to the target and ideally should fall within +/- 2 SD from the mean. By falling within these limits a lab can be sure of accurate results and an acceptable performance.
Employ Acusera quality controls in your laboratory today and experience unrivaled confidence in your test results.

Measurement of Uncertainty relates to the doubt that exists for the result of any measurement. For every measurement there is always a margin of doubt and therefore we need to ask ‘How big is the margin?’ and ‘How significant is the doubt?’.
In a hospital or healthcare environment, the clinician must be certain that any change identified in a patient’s test results is not a change to the laboratory test system but a change to the patient’s status. This is especially critical at clinical decision levels. Randox Quality Control has developed a guide to Measurement of Uncertainty in response to the demand for more information on the topic within the industry. This guide outlines what Measurement of Uncertainty is, how to measure uncertainty, factors which affect uncertainty and it’s sources.

Importance of using third party controls
The importance of using third party controls cannot be overlooked. Using these controls can help to identify instrument, reagent and procedural errors which, if undetected could lead to the reporting of incorrect patient results!
What is a third party control?
ISO 15189:2012 states “the use of third party control materials should be considered, either instead of, or in addition to, any control materials supplied by the reagent or instrument manufacturer.” True third party controls are not optimised for use with a specific reagent or test system and therefore are renowned for delivering unbiased performance assessment with any instrument/method. The manufacturers of third party controls will usually assign values based on data collected from thousands of independent reference labs – thus ensuring the availability of statistically valid data for a wide range of platforms. Due to their independent nature and objectively assigned values you can be sure that third party controls will provide unbiased error detection across multiples platforms and methods.
First party control
Conversely, first party controls are analyser dependent controls that are supplied by the instrument/reagent manufacturer and are optimised specifically for use with the manufacturers test system and therefore will often mask weaknesses which could lead to the release of incorrect patient test results. These dependent controls are considered to lead to perceived accuracy and a biased assessment of performance.
Acusera third party controls
The Randox Acusera range of multi-analyte controls are true third party. Our controls have been designed to deliver an independent, unbiased assessment of performance with instrument or method. Our unique value assignment process employs thousands of independent laboratories ensuring statistically valid targets are available for most laboratory instruments. The availability of multi-analyte, multi-instrument controls with a shelf life of up to 4 years not only ensures continuity of lot supply but will significantly reduce costs and preparation time by reducing the need for multiple instrument specific controls.
Case Study 1
A laboratory running Acusera Immunoassay Premium Plus Control reported their QC results for Thyroglobulin were four times higher on the their main analyser compared to other systems.
They ran the instrument manufacturer’s control alongside the Acusera control but it did not show the same problem.
After reviewing EQA data, the Randox Technical Services team confirmed there was a significant difference in results compared to other instruments.
The customer contacted their instrument manufacturer, who advised of a positive bias with several batches of reagent.
In summary, the Randox Immunoassay Control detected a shift in results that the instrument dedicated control did not.
Case Study 2
A laboratory noticed an increase in native patient sample result recovery of around 15-20%. The lab were running their Gentamicin reagent along with a TDM calibrator. Over recovery was also noted for EQA samples however, the issue had not been detected with their current control set.
The laboratory got in touch with Randox about the use of our controls and if they would experience the same problems with our controls as they are with their current provider. We assured the laboratory that our controls were true third party and the unique 100% human serum matrix would provide a sample as close as possible to that of the patient.
The laboratory decided to test a sample of Acusera TDM control and were delighted with the results. They purchased some of our therapeutic drug controls and have yet to experience any increase in the result recovery of patient samples highlighting the need to use true third party controls.
This case study once again highlights how important running true third party controls is to a laboratory. It can be the difference between them reporting accurate and reliable patient test results and reporting incorrect results that could lead to a misdiagnosis which could be fatal to the patient on the receiving end.
Manage Your Laboratory Effectively with Randox Quality Control
With Euro 2016 starting today the final squads for each country participating have been carefully selected.

A recent report published by Markets and Markets called “In Vitro Diagnostics (IVD) Quality Controls Market” has highlighted the significant growth within the Quality Control market, with further growth expected within the next 4 years, estimating that the IVD QC market will be worth $979 million. The report is crediting this growth to “the increasing number of accredited clinical laboratories and growing adoption of third-party quality controls”. It also indicates an anticipated growth of 4.7% CAGR between 2015 -2020 for third party quality controls. The adoption of third party controls is particularly interesting, as a survey conducted by Randox in 2015 found that only 35% of respondents felt that the most important feature when selecting quality controls for the laboratory was that they were third party, with stability being the top choice. This highlights the influence accreditation is having within the IVD market.
Why have these been influential?
Accreditation to ISO 15189:2012, and other similar standards, is becoming mandatory in many countries. Laboratories are becoming accredited to highlight the accuracy and reliability of the patient results they are releasing. Furthermore such accreditation standards and the industry regulatory bodies, like CAP, CLSI and so on, are recommending the use of third party controls. This is supported by ISO 15189:2012 which states, “the use of third party control materials should be considered, either instead of, or in addition to, any control materials supplied by the reagent or instrument manufacturer”. The report states that third party controls “offer various advantages over other types” of quality controls, this includes a longer shelf life and long term quality monitoring.
What can Randox Quality Control Offer?
The Acusera range of quality controls can be described as true third party or independent controls. Unlike first party controls or semi dependent controls they are manufactured independently of any instrument or reagent and thus are designed to deliver an unbiased assessment of analytical performance across all platforms while also meeting ISO 15189:2012 recommendations. To assist with the other requirements of ISO 15189:2012 each control is 100% commutable, ensuring a matrix that will react to the test system in the same manner as a patient sample. It should also be noted that the entire Acusera quality control range has been manufactured in line with clinically relevant decision levels. Employing controls that cover the entire clinical range will eliminate the need for separate low/high controls ultimately reducing costs while also ensuring accurate instrument performance. By employing any one of our Acusera Controls in your laboratory you could minimise costs & limit the time spent reassigning values after each lot change, highlighting just some of the additional benefits of employing a third party control.

With more than 30 years’ experience developing pioneering high quality, cost effective Quality Control solutions for the IVD market Randox has designed their Acusera range of third party controls to simplify QC practice for labs of all sizes. The following outlines frequent complaints that arise in the lab & solutions we can offer to ensure you no longer quietly complain about your QC.
High volumes of controls needed to assess your test menu?
Acusera controls can contain a unique combination of up to 100 analytes in a single vial. This consolidation will permit you to reduce costs by removing the need to purchase extra controls to cover your complete test menu. As fewer controls are required the amount of time spent preparing controls is reduced, freeing staff to complete other tasks.
QC does not contain clinically relevant levels?
The analytes present in our Acusera controls have been included at clinical decision levels. The importance of employing controls that cover clinically relevant concentrations is highlighted by ISO 15189 & its significance is demonstrated in the following example. When measuring Troponin T the cut off value is 14 ng/l. Patients who present to the hospital with a concentration higher than 14 ng/l in their blood are said to have had a cardiac event. Test results lower than 14 ng/l would indicate that the patient is healthy or it is too early to tell if a cardiac event has occurred. As such it is imperative that analysers can accurately measure to this level and that performance at this level is assessed. QC material with similar cut off levels should therefore be used. Acusera meets these requirements, reducing the number of controls you need to cover both your complete test menu & the necessary clinical decision range for specific tests.
Frequent expensive lot changes?
With a shelf life of up to 2 years for liquid & 4 years for lyophilised controls, Acusera can help minimise costly lot changes. Furthermore each control has their own target values & extended open vial stability claims, which do not differ from lot to lot due to our unrivalled consistency. Both features will ultimately help reduce waste, minimise costs & limit the time spent reassigning values after each lot change.
When using controls with non-human components you are likely to experience shifts in QC values when changing reagent batch. Our controls are 100% commutable, reacting to the test system in the same manner as a patient sample, helping you to not only meet ISO requirements but reduce costly QC shifts.
Need to improve confidence in QC results?
Acusera 24.7 is an interlaboratory data management designed for use with Randox true third party controls. The software has been created to help monitor and interpret QC data, providing access to; QC multi-rules, interactive charts, real-time peer group data and our unique dashboard interface for at-a-glance performance assessment.
With Acusera you will no longer quietly complain about your QC!
