Get your teeth into a Randox commutable control this Halloween
It is that time of year again – when people dress up, children trick-or-treat and many a scary story is told in households around the world. An age-old tradition celebrated globally by millions of people – it can only be Halloween.
Last year Randox QC brought you the truly scary story about a laboratory who chose not to use a third party control, but eventually “treated their laboratory to a true third party control”. This year, we have another scary story for you about a lab manager in Transylvania, Dr. Acula.
It was a normal, busy day in the lab for Dr. Acula. That was until it was time to change reagent batch, after changing batch of reagent Dr. Acula was shocked to find his QC results had shifted by over 20%. This left Dr. Acula very frustrated, having to spend precious time troubleshooting and reassigning QC targets. After troubleshooting showed no apparent root cause, Dr. Acula searched the internet for an answer finally stumbling upon an educational guide from Randox Quality Control on commutability and its many benefits to the lab.
Grinning from ear-to-ear with excitement, Dr. Acula began to read the guide in the hope of finding a solution to his problem – and solutions he found. While reading the guide, Dr. Acula came across a quote from ISO 15189:2012. It read that laboratories “must use quality control materials that react to the examining system in a manner as close as possible to the patient sample”.
Dr. Acula made a decision to look for a commutable control material that met all of his requirements and he didn’t have to search very far. Randox Quality Control were able to supply Dr. Acula and his laboratory with a QC material to meet all his needs – true third party, excellent stability, consistency and consolidation but most importantly of all commutable controls. The fact all Randox immunoassay and immunology controls are manufactured from 100% human material appealed to Dr. Acula a lot. After trialing the Randox control material alongside patient samples and comparing results between reagent batches, Dr. Acula was thrilled with the results.
Labs rely heavily on quality control to detect errors in their test system and to ultimately make critical decisions regarding the accuracy and reliability of patient test results, the use of a control that reacts to the test system in the same manner as a patient sample is therefore essential.
At Randox Quality Control we take quality seriously. All our QC products are manufactured to the highest possible standard ensuring controls of unrivalled quality time and time again. Designed to be commutable, the Acusera range will ensure accurate and reliable instrument performance while simultaneously helping laboratories meet ISO 15189:2012 requirements.
Just ask Dr. Acula, who likes our 100% human controls so much he has started to drink them himself!
Don’t Get Tricked This Halloween – Treat Your Lab to Randox True Third Party Controls Today!
Halloween – a celebration observed by many countries around the world on a yearly basis. Falling on October 31st this holiday is a chance for people to dress up, carve pumpkins, bob for apples, attend costume parties, trick-or-treat and tell scary stories.
It just so happens that we have a scary story for you – and what makes this story even scarier is that it’s a true story!
Our story starts off in a medical laboratory. This laboratory was running QC on their machine as they would do every day. Getting accurate results with no faults or problems arising from their machine, this laboratory was happy with how things were going – until one day when it all went wrong!
Having run their EQA/PT samples, the laboratory found themselves reviewing their report with shock –they noticed a large negative bias. To their horror the perceived ‘accuracy’ they had once achieved was now no longer the case. Right away the laboratory professional’s thoughts turned to the fact that approx. 70% of all clinical decisions are based on laboratory test results, meaning it is essential that the results provided are accurate and reliable in order to prevent potential misdiagnosis or inappropriate treatment. Had they sent incorrect patient results to the clinicians? Had a patient been misdiagnosed? Many thoughts fluttered around in their heads.
The laboratory repeated their QC and found that the results obtained were almost identical to the previous run. The laboratory knew there must be a problem with their QC or their instrument, so they began the troubleshooting process. Nothing. Nada. Zilch. “What was going on?” was the question on the lips of the laboratory professionals.
One of the laboratory professionals then stumbled across a case study that took place in the University of Verona and Academic Hospital of Parma, Italy. The study was related to a field recall of Intact PTH, the reagent was recalled after falsely elevated patient results were discovered. The alarming thing was that the same elevated performance was not identified by the instrument manufacturer’s control. The study reported that due to this issue there was potential for 40,000 inaccurate patient results from just 18 labs in the Lombardy region of Italy. The study also concluded that the issue could have been prevented if a third-party control, independent from calibrator materials had been used.
This PTH case study got the laboratory thinking that maybe they should source a true third party manufacturer… Having sampled a third party QC, the lab found their results now mirrored that of their EQA and patient samples and as such proceeded to make the switch from first party to third party.
The moral of this story is that first party controls can sometimes “trick” the lab into thinking their performance is acceptable. Quite often target values provided with first party quality controls are in the middle of the analytical range thus masking the issues at the low and high ends of the assay range. Laboratory professionals should “treat” their labs to the best QC material. ISO 15189 highlights that the “use of independent third party control materials should be considered, either instead of, or in addition to, any control materials supplied by the reagent or instrument manufacturer”. So this Halloween don’t randomly choose your QC supplier, treat your laboratory to the best, Randox QC.
All Randox controls are manufactured independently of any instrument or reagent, and designed for use with multiple instruments and methods ensuring, unbiased performance assessment.
