Product Spotlight: Liquid Cardiac Control

product spotlight - liquid cardiac control

Liquid Cardiac Control

The Randox Acusera Liquid Cardiac Control is designed to be both convenient and easy to use. The liquid ready-to-use format makes it ideal for both clinical laboratories and point-of-care testing. Assayed, instrument specific values are provided for an impressive 8 cardiac markers including, NT-ProBNP, D-dimer and Troponin ensuring consolidation and flexibility. Furthermore, an open vial stability of 30 days for all analytes helps to keep waste and costs to a minimum.

Background

A myocardial infarction or heart attack is a serious medical emergency where the blood supply to the heart is blocked, usually by a blood clot. A lack of blood to the heart may seriously damage the heart muscle and can be life-threatening (NHS, 2016).

When blood flow to the heart is reduced or blocked for a length of time, damage to cardiomyocytes (heart muscle cells) results in the release of cardiac troponin. The consequent rise and/or fall in troponin levels can distinguish an acute MI from other cardiac conditions.

Troponin I & Troponin T

Cardiac troponin I and cardiac troponin T are biological markers of cardiac muscle death (cardiomyocyte necrosis). Troponins I and T come form the troponin‑tropomyosin complex which is responsible for regulating cardiac muscle contraction. Troponins I and T are the recommended biomarkers for diagnosing myocardial infarction (MI) in cases of chest pain when a rise and fall in troponin levels can signify that myocardial damage has occurred.

The optimum sensitivity of non‑high‑sensitivity troponin assays for acute MI occurs 10–12 hours after the onset of symptoms, often resulting in need for hospital admission and repeated troponin testing. To overcome this, a troponin assay with high‑sensitivity can be used. These can detect lower levels of troponin in the blood earlier, leading to faster detection of acute MI. (National Institute for Health and Care Excellence, 2014)

Quality Control is a vital component of any laboratory helping to ensure accurate test system performance. Quality Control is of particular importance at medical decision levels, as such controls that contain ultra-sensitive levels of Troponin are essential.

Key Benefits & Features

Mythbusting: ‘Using IQC and EQA From the Same Provider Leads to QC Bias’

Some laboratory professionals believe that using Internal Quality Control (IQC) and External Quality Assurance (EQA, also known as Proficiency Testing) material from the same provider can lead to increased levels of qc bias, or that their test system will not be appropriately challenged. It is important to address these concerns, because some labs may in fact be hindering their own performance by using IQC and EQA material from different sources.

It is important to first understand how IQC and EQA work together to help form a complete Laboratory Quality Management System.

IQC and EQA in Laboratory Quality Management

IQC is a means of monitoring test system precision on a daily basis. IQC effectively evaluates test system performance over time, so that any sudden or gradual shifts in performance can be detected. However, while IQC is an effective performance monitor, it cannot detect more intricate problems like calibration errors or wide acceptable limits provided by some QC manufacturers.

EQA is essential for challenging test system accuracy, and is carried out less frequently than IQC testing. EQA samples are tested ‘blind’ and the results are returned to the scheme organiser. As EQA testing compares an individual lab’s performance to other labs using the same method and instrument, it is a very effective tool for identification of potential issues.

Is there any disadvantage to using IQC and EQA material from the same provider?

The answer to this question depends primarily on the source material of the IQC and EQA. If an IQC provider manufactures their material using artificial additives or components of animal origin, then it will not be suitable to use EQA material from the same provider. Westgard (2011) maintains that using non-commutable IQC or EQA material can lead to results becoming compromised due to matrix effects – something which would not happen using commutable controls.

For example, with Immunoassay testing, non-human components of IQC material interact with antibodies in the reagent in a different way to fully human patient samples – ultimately giving unpredictable shifts, and not adhering to the ISO 15189 requirement to: “use quality control materials that react to the examining system in a manner as close as possible to patient samples”.

However, if the IQC and EQA material is manufactured using a source material which is similar in composition to patient samples (100% human), this commutable control will adequately mimic patient sample performance; meaning labs can use EQA and IQC material from the same provider with confidence that the integrity of their results is maintained.

Conclusion

ISO 15189 also states: “Use of independent third party control materials should be considered…”. In this instance, ‘Independent’ does not mean from a separate provider. It means that the QC material should not be optimized for use on one specific instrument (i.e. not dependent on a single instrument/method type).

No regulatory body states a requirement to use different providers for IQC and EQA material. Indeed, using IQC from one provider and EQA from another provider could increase the risk of labs using non-commutable material.

Labs should use commutable IQC and EQA material for a true assessment of their test system. Randox QC and RIQAS EQA are specifically designed with commutability in mind, giving labs a control which reflects patient sample performance and ensures excellent performance.

Product Spotlight: Maternal Screening

Product Spotlight: Maternal Screening Control

Maternal Screening Control

Background

A maternal serum screening test (MSS) is a blood test offered to pregnant women that helps determine the risk of Down’s syndrome and other chromosomal conditions, further testing can be offered if the patient is found to be high risk. It can be performed at 10 weeks (combined first trimester screening test), and 14-20 weeks (second trimester maternal serum screening test).

MSS is generally offered to all pregnant women, but the decision to have the test is a personal decision.

Quality Control is an important part of any diagnostic test but is of particular importance in screening methods, when a disorder must be detected without the presence of symptoms. In such screening methods, errors can present as false negative or false positive results both of which can have devastating consequences.  In the case of maternal screening a false positive result could mean additional and often invasive procedures which can carry risk of harm to the unborn child. The accuracy and reliability of the laboratory test results are extremely important in minimising both false positive and false negative results.

Product Overview

The Randox Acusera Maternal Screening quality control is the only commercially available control which covers all six analytes used during first and second trimester screening of Down’s syndrome and Spina Bifida.

Instrument specific target values and ranges are provided for AFP, Inhibin A, PAPP-A, β hCG, Total hCG and Unconjugated Estriol. The inclusion of PAPP-A and Inhibin A eliminates the need to purchase additional controls at extra expense.

Product Focus: Randox HbA1c

This month’s product spotlight is our new Liquid HbA1c Control. Over the next few weeks, we will be taking a look at some of the QC solutions available from Randox for HbA1c.

Haemoglobin is an oxygen-transporting protein found inside Red Blood Cells (RBC). Glycated Haemoglobin is simply a haemoglobin with a glucose molecule attached. The higher the level of glucose in the blood the more glycated haemoglobin is formed. Red Blood Cells live for around 2-3 months, because of this the HbA1c test is used by clinicians to get an overall picture of average blood sugar levels for the last 2-3 months. For people with diabetes this is important as the higher the HbA1c, the greater the risk of developing diabetes-related complications. It is suggested that an individual’s HbA1c target should be under 48mmol/mol or below 6.5%. By lowering your HbA1c, you help reduce the risk of long-term health problems.

HbA1c is used to monitor patients with diabetes providing an indication of how well the condition is controlled. A measurement of less than 6% of HbA1c in the sample indicates good glucose control and a lower risk of diabetic complications for the majority of diabetics.

Week 1: HbA1C Quality Control

The Randox Acusera HbA1c control is designed for use in the quality control of both HbA1c and Total Haemoglobin assays.

Product Focus: Calibrators

Calibrators

The importance of accurate instrument calibration in the laboratory is often overlooked. At Randox Quality Control we believe that accurate calibration is the foundation for producing reliable patient results. In fact, we believe that this should be your first step in ensuring accurate instrument performance and something you should consider carefully.

Effective instrument calibration will provide you with a baseline for your analysers from which accurate results can be produced. This baseline is then used to adjust readings to match the computed value and ensure accurate patient results are reported.

Calibrator features you should consider;

As well as frequent recalibration, according to the instructions provided by the instrument / reagent manufacturer, Randox Quality Control recommends;

  • Utilising a third party calibrator, such as those available from our Acusera range, which have independently assigned values and have not been optimized for use with any specific instrument or reagent system
  • Ensuring the calibrator you employ has the same matrix as a patient sample
  • Choosing a calibrator that is 100% commutable, ensuring it mimics the behaviour of a patient sample
