The scary facts about cholesterol!

The scary facts about cholesterol!

Cholesterol is a fatty substance also known as a lipid. It is made by the liver but can also be found in some foods. It is essential to let the body function normally. You will be sad to hear that high levels can increase your risk of serious health conditions. There are two main types; high-density lipoproteins (HDL) and low-density lipoproteins (LDL). HDL is known as good cholesterol. It carries cholesterol back to the liver, where it is broken down. LDL on the other hand carries cholesterol to the cells however if there is a surplus it can build up in the artery walls increasing the chances of a heart attack or stroke occurring.

Here are some scary facts about cholesterol…

  1. You can’t live without it – Cholesterol has been in your body since the day you were born. It is a building block for all cells.  Not only that but all of our cells and hormones need it to function properly…unfortunately you are very unlikely to find good cholesterol in your typical trick-or-treat offerings.
  1. Not all patients on cholesterol-lowering medication respond optimally to it – In the recent past, aspirin (a drug used to reduce levels) was prescribed for people who had a perceived risk of a heart attack. However aspirin does not always work; up to 30% of patients could have a below optimum response to the drug and therefore be at a considerably increased risk of a recurrent cardiovascular event. This is may also be referred to as “aspirin resistance”.
  1. One third of adults have high cholesterol – Testing is advised every 5 years to monitor your levels to see any changes. To get the most accurate results tests should be carried out one week apart, however most testing facilities won’t follow this.
  1. High levels could be down to genetics – Diet you can change, genes you can’t! If your family has a history of high cholesterol then you are likely to have it as well. It has been suggested that 75% of cholesterol is due to genetics and the remaining 25% is down to diet and lifestyle choices.
  1. Women’s levels will fluctuate over their lifespan – Did you know that ladies? During the average woman’s lifespan, cholesterol levels will rise and fall due to pregnancy and menopause. During pregnancy levels will rise in order to help the baby develop. After birth the mother’s levels should return to normal however after menopause a woman’s LDL levels will rise to that higher of a man’s.

However it is not all doom and gloom this Halloween!  Randox are here to treat you to a vast range of specialised blood tests to allow the most accurate diagnosis of cholesterol levels, allowing you to gauge how many sweets you can sneak in this Halloween! We offer a large array of routine and niche tests. The most popular and widely tested are HDL, LDL, total cholesterol and triglycerides. Some further risk assessment cholesterol tests which are not routinely run include sLDL, HDL3, Lp(a). These cholesterol biomarkers are also affected by the usual risk factors such as age, weight, smoking, etc.; however they can also be a result of one’s genes. As mentioned before aspirin resistance is a big problem affecting up to 30% of all patients on aspirin therapy. However Randox offer the TxBCardio™ test which is a unique test to diagnose and assess the effectiveness of aspirin therapy.

From all of us here at Randox we wish you a safe and happy Halloween!

Protect your family from early heart disease with a simple blood test

On World Heart Day 2015, Randox Laboratories unveiled a rapid, highly accurate diagnostic test to identify individuals with familial hypercholesterolemia (FH), a common disorder that is passed from parents to their children. FH is often called the ‘silent killer’ as it is characterised by dangerously high levels of cholesterol, leading to early onset cardiovascular disease. The good news is that if diagnosed, FH can be effectively treated; the even better news this National Cholesterol Month is that this new test has made diagnosis across the UK much simpler.

Thousands of families in the UK are affected by FH, as not only is heart disease the number one killer across the globe, there is a 50:50 chance that a parent with FH will pass it onto their children. The condition can lead to higher risk of a heart attack in men before the age of 50, or before the age of 60 in women.

A common disease, at least 1 in every 500 people in the UK are living with FH, although new international research suggests that 1 in every 200 people could be affected, which would mean as many as 300,000 people in the UK. Worryingly, it is substantially underdiagnosed and less than 12% of people with FH in the UK are aware that they have this potentially life-threatening condition.

The current recommended screening techniques are costly and time consuming, limiting the number of individuals who benefit from a timely diagnosis. Under NHS guidelines, when a person is found to have FH, their closest blood relatives should get tested too – including children before the age of 10. The new test allows definitive diagnosis within one day, rather than the usual weeks or even months for current tests, removing unnecessary anxiety and allowing people to take immediate action before it’s too late.

The new molecular test that has been developed by Randox Laboratories in Crumlin, Northern Ireland, in partnership with the Belfast Health and Social Care Trust, enables detection of the 40 most common genetic mutations that cause FH in the UK, with results available in just three hours. With early and appropriate treatment, such as adopting a healthy lifestyle and taking cholesterol-lowering medication, risk of heart disease can be significantly reduced so that someone with FH can live as long as a person who doesn’t have the condition.

Professor John Chapman, Past- President of the European Atherosclerosis Society, which promotes study into the causes of accelerated atherosclerosis and cardiovascular disease, has welcomed the new test for suspected cases of FH:

“FH is a serious condition for those with a family history of accelerated atherosclerosis and premature cardiovascular disease. With this information, preventative measures including diet, lifestyle and lipid lowering drugs can be successfully introduced. Indeed, early identification and prevention can significantly benefit all family members potentially with this condition. In fact, we are entering an exciting time in the treatment of those with cardiovascular disease as new and highly effective drugs for lipid management are becoming available.”

The test, which is available through Randox Health Clinics, has been adopted by medical professionals within the NHS, including Dr. Colin Graham, recently retired Consultant Clinical Scientist and former Head of the Regional Genetics Lab in the Belfast Health and Social Care Trust, who introduced the test within his Belfast Laboratory screen for suspected cases of FH:

“The launch of this new clinically available test is a key milestone in the detection and diagnosis of FH. Current FH diagnostic tests require a large volume of samples to be batched, leading to lengthy turnaround times of two to three months. With the new test, the turnaround time is dramatically reduced, enabling more rapid patient diagnosis.”

Dr. Graham also highlighted the importance of improving detection rates through the screening of wider patient populations:

“This new test has the potential to enable FH screening to become routine in the clinical setting for improved detection and earlier identification of familial cases.”

Dr. Peter FitzGerald, Managing Director of Randox Laboratories said:

“In the battle against cardiovascular disease, people with FH are on the front line. On World Heart Day it is important to raise awareness of FH as many people do not even know that they and their family members have this life-threatening condition. There is so much that can be done to support families with FH and with this readily available and much-needed test, detecting and treating entire families with FH is now possible.”
