Measurement Uncertainty Vs Total Error
In a recent article, Error Methods Are More Practical, But Uncertainty Methods May Still Be Preferred, James Westgard comments on the latest developments in the debate on the use of analytical total error (TE) and measurement uncertainty (MU), a debate which has been regularly revisited for the last twenty years. This blog aims to briefly explore the benefits of MU and TE and attempt to draw a conclusion on which is most beneficial in the clinical laboratory.
Many things can undermine a measurement. Measurements are never made under perfect conditions and in a laboratory, errors and uncertainties can come from (Good Practice Guide No. 11, 2012):
- The measuring instrument – instruments can suffer from errors including bias, changes due to ageing, wear, poor readability, and noise.
- The item being measured – the sample may be unstable.
- The measurement process – the analyte may be difficult to measure
- ‘Imported’ uncertainties – calibration of the instrument.
- User error – skill and judgement of the operator can affect the accuracy of a measurement.
- Sampling issues – the measurements you make must be properly representative of the process you are trying to assess. I.e. not using fully commutable controls will mean your quality control process is not reflective of a true patient sample.
Random and systematic errors
The effects that give rise to uncertainty in a measurement can be either random or systematic, below are some examples of these in a laboratory.
- Random – bubbles in reagent, temperature fluctuation, poor operator technique.
- Systematic – sample handling, reagent change, instrument calibration (bias), inappropriate method.
Total Error (TE) or Total Analytical Error (TAE) represents the overall error in a test result that is attributed to imprecision (%CV) and inaccuracy (%Bias), it is the combination of both random and systematic errors. The concept of error assumes that the difference between the measured result and the ‘true value’, or reference quantity value, can be calculated (Oosterhuis et al., 2017).
TE is calculated using the below formula:
TE = %BIAS + (1.96 * %CV)
Measurement Uncertainty is the margin of uncertainty, or doubt, that exists about the result of any measurement.
There is always margin of doubt associated with any measurement as well as the confidence in that doubt, which states how sure we are that the ‘true value’ is within that margin. Both the significance, or interval, and the confidence level are needed to quantify an uncertainty.
For example, a piece of string may measure 20 cm plus or minus 1 cm with a 95% confidence level, so we are 95% sure that the piece of string is between 19 cm and 21 cm in length (Good Practice Guide No. 11, 2012).
Standards such as ISO 15189 require that laboratories must determine uncertainty for each test. Measurement Uncertainty is specifically mentioned in section 5.5.8.3:
“The laboratory shall determine measurement uncertainty for each measurement procedure in the examination phases used to report measured quantity values on patients’ samples. The laboratory shall define the performance requirements for the measurement uncertainty of each measurement procedure and regularly review estimates of measurement uncertainty.”
Uncertainty is calculated using the below formula:
u = √A2+B2
U = 2 x u
Where:
A = SD of the Intra-assay precision
B = SD of the Inter-assay precision
u = Standard Uncertainty
U = Uncertainty of Measurement
Error methods, compared with uncertainty methods, offer simpler, more intuitive and practical procedures for calculating measurement uncertainty and conducting quality assurance in laboratory medicine (Oosterhuis et al., 2018).
It is important not to confuse the terms ‘error’ and ‘uncertainty’.
- Error is the difference between the measured value and the ‘true value’.
- Uncertainty is a quantification of the doubt about the measurement result.
Whenever possible we try to correct for any known errors: for example, by applying corrections from calibration certificates. But any error whose value we do not know is a source of uncertainty (Good Practice Guide No. 11, 2012).
While Total Error methods are firmly rooted in laboratory medicine, a transition to the Measurement Uncertainty methods has taken place in other fields of metrology. TE methods are commonly intertwined with quality assurance, analytical performance specifications and Six Sigma methods. However, Total Error and Measurement Uncertainty are different but very closely related and can be complementary when evaluating measurement data.
Whether you prefer Measurement Uncertainty, Total Error, or believe that they should be used together, Randox can help. Our interlaboratory QC data management software, Acusera 24•7, automatically calculates both Total Error and Measurement Uncertainty. This makes it easier for you to meet the requirements of ISO:15189 and other regulatory bodies.
This is an example of the type of report generated by the 247 software. MU is displayed for each test and each lot of control in use therefore eliminating the need for manual calculation and multiple spreadsheets.

C-Reactive Protein (CRP)
CRP is a protein made by the liver and released into the blood within a few hours after tissue injury, the start of an infection, or other cause of inflammation. It is tested to detect the presence of inflammation and can be used to monitor the response to treatment for inflammatory disorders. CRP is included in the Liquid Assayed Chemistry Premium Plus control, ensuring accurate instrument performance at key decision levels and further reduces the number of individual controls required. CRP is available at elevated levels in the level three control.
Troponin T (TnT)
A troponin test measures the levels of troponin proteins in blood and is used when a patient is suspected to have suffered a heart attack. These proteins are released when the heart muscle has been damaged, such as with a heart attack. More damage to the heart would result in a higher level of Troponin T. As a highly consolidated contorol, the Liquid Assayed Chemistry Premium Plus includes Troponin T, meaning a separate control is not required.
The Importance of Meeting ISO 15189 Requirements
Laboratory accreditation provides formal recognition to competent laboratories, providing a means for customers to identify and select reliable services (CALA, n.d.). Use of accreditation standards by clinical laboratories enables them to drive gains in quality, customer satisfaction, and financial performance. This is essential at a time when laboratory budgets are shrinking.
Some key benefits include:
- Recognition of testing competence – as mentioned above, customers can recognise the competence of a lab with an internationally recognised standard.
- Marketing advantage – accreditation can be an effective marketing tool as labs can demonstrate their quality and overall competence.
- Benchmark for performance – laboratories can determine whether they are performing to the appropriate standards and provides them with a benchmark to maintain that standard.
To maintain the global recognition gained from accreditation, labs are evaluated regularly by an accreditation body to ensure their continued compliance with requirements, and to check that standards are being maintained. (CALA, n.d.).
In a comprehensive study conducted by Rohr et al. (2016) it was found that, while accounting for as little as 2% of total healthcare expenditure, in vitro diagnostics (IVD) account for 66% (two thirds) of clinical decisions. Despite such a small percentage of budget dedicated to it, IVD plays a huge role in patient care so it is vital that there is guidance in place to ensure quality standards are met. Poor performance of tests at any stage of care and treatment can reduce the effectiveness of treatment and deny appropriate care to patients in need (Peter et al., 2010).
ISO 15189 is an international accreditation standard that specifies the quality management system requirements particular to medical laboratories and exists to encourage interlaboratory standardisation, it is recognised globally.
Meeting ISO Requirements
Scroll through below to learn how ISO 15189 regulates aspects of a clinical laboratory and how Randox can help you meet these suggestions.
Review of QC data
“The laboratory shall have a procedure to prevent the release of patient results in the event of quality control failure. When the QC rules are violated and indicate that examination results are likely to contain clinically significant errors, the results shall be rejected…QC data shall be reviewed at regular intervals to detect trends in examination performance”
– ISO 15189:2012
Acusera 24∙7 will automatically apply QC multi-rules, alert you to or reject any results that violate the QC multi-rules or performance limits, generate a variety of charts allowing visual identification of trends and provide access to real-time peer group data to assist with the troubleshooting process.
Calculation of MU
“The laboratory shall determine measurement uncertainty for each measurement procedure in the examination phases used to report measured quantity values on patients’ samples. The laboratory shall define the performance requirements for the measurement uncertainty of each measurement procedure and regularly review estimates of measurement uncertainty.”
– ISO 15189:2012
Acusera 24∙7 is the only QC data management platform that incorporates the automatic calculation of Measurement Uncertainty (MU) as well as other performance metrics, including Total Error.
More about Measurement Uncertainty and how Acusera 24∙7 can help
Commutability
“The laboratory shall use quality control materials that react to the examining system in a manner as close as possible to patient samples”
– ISO 15189:2012
Acusera True Third Party Controls are fully commutable, behaving like a real patient sample, reducing the need to re-assign QC target values when the reagent batch is changed, reducing labour and costs.
Medical decision levels
“The laboratory should choose concentrations of control materials, wherever possible, especially at or near clinical decision values, which ensure the validity of decisions made”
– ISO 15189:2012
Acusera True Third Party Controls are designed to challenge instruments across the entire clinical reporting range.
Comparison of results across instruments
“Laboratories with two or more analysers for examinations, should have a defined mechanism for comparison of results across analysers”
– ISO 15189:2012
Acusera 24∙7 is capable of combining multiple data sets on a single Levey-Jennings, Histogram of Performance Summary chart, enabling at-a-glance performance review and comparative performance assessment. A unique multi-instrument report is also available via our RIQAS EQA programme allowing performance of each instrument to be compared.
Third Party Control
“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”
– ISO 15189:2012
Acusera True Third Party Controls are manufactured completely independently of and calibrators and assigned values through a pool of instruments across the world, making them true third party controls.
At a conference in Belgium in 2016, data, which highlighted the most common areas of non-conformance in laboratories, showed that nonconformities were most prevalent in sections 5.5 and 5.6 of ISO 15189. This data is visualised in fig. A below. Furthermore, a study by Munene et al. (2017) has had similar findings, as visualised in fig. B. The greatest number of nonconformities occur in the sections that are concerned with insufficient assay validation and quality of examination procedures. These studies specifically identified the lack of independent controls, QC not at clinically relevant levels, commutability issues, and a lack of interlaboratory comparison as major issues.
Randox Quality Control products are designed to target these areas, making it easier to conform to ISO 15189 standards.

Benefits of High-Sensitivity Troponin I (hs-TnI)
Benefits of High-Sensitivity Troponin I (hs-TnI)
Chest pain is a common symptom; 20% to 40% of the population will experience chest pain during their lifetime. There are many causes of chest pain, some of which are benign, while others are potentially life threatening. Importantly, in patients with chest pain caused by an acute coronary syndrome (ACS) or angina, there are effective treatments to improve symptoms and prolong life, emphasising the importance of early diagnosis in patients where chest pain may be of cardiac origin (Skinner et al, 2010). Chest pain is one of the most common reasons for emergency admission to hospital and is a heavy burden on health-care resources. A strategy to identify low-risk patients suitable for immediate discharge would have major benefits (Shah et al., 2015).

Product Spotlight: Liquid Lipid Control
Cardiovascular disease (CVD) is a general term for conditions affecting the heart or blood vessels. It is usually associated with a build-up of fatty deposits inside the arteries and increased risk of blood clots. It can be associated with damage to arteries in organs such as the brain, heart, kidney and eyes. Some types of CVD include coronary heart disease, strokes and aortic disease. Some of the main causes of CVD are smoking, high cholesterol, diabetes and high blood pressure (NHS, 2016).
These diseases can be extremely dangerous and lead to permanent damage or even death, therefore, it is vitally important for laboratories to be confident in their analyser’s ability to accurately diagnose and monitor the risk of these diseases.
The Randox Acusera Liquid Lipid quality control includes assayed target values and ranges for 8 analytes covering the complete lipid profile. With a 30 day open vial stability the Acusera Liquid Lipid control will reduce waste, whilst remaining easy and convenient to use. Three distinct levels are available covering low risk, borderline risk, and high risk concentrations of HDL and LDL cholesterol, ensuring the clinically relevant decision levels are tested, eliminating the need to purchase additional high and low level controls. Containing no Sodium Azide, which can interfere with direct clearance methods for detecting HDL and LDL cholesterol, ensuring ultimate accuracy and confidence in results.

Analytes
Apolipoprotein A | Apolipoprotein B | Cholesterol (HDL) | Cholesterol (LDL)
Cholesterol (Total) | C-Reactive Protein (CRP) | Lipoprotein (a) | Triglycerides
HDL Cholesterol
High-Density Lipoproteins (HDL) are one of the major classes of plasma lipoproteins. HDL is often referred to as ‘good cholesterol’ because it transports cholesterol from the tissues of the liver for removal from the body. High levels of HDL can indicate a lower risk of developing heart disease.
Apolipoprotein A-1
Apolipoprotein A-1 is one of the main protein forms found in High Density Lipoproteins (HDL). The chief role of Apolipoprotein A-1 is in the activation of lecithin cholesterol acyltransferase (LCAT) and the capture and removal of free cholesterol from extra hepatic tissue. Studies have shown that there is an inverse relationship between Apolipoprotein A-1 and coronary artery disease (CAD).

Meeting ISO 15189:2012 Requirements for Multiple Instruments
Approximately 70% of clinical decisions are based on laboratory test results. Poor laboratory quality can result in unreliable test results ultimately leading to misdiagnosis, inappropriate treatment and may even impact the overall quality of life for the patient. Having multiple instruments can often add to the difficulties faced in labs. The importance of quality medical services is recognised globally with several bodies existing internationally including ISO (International Organisation for Standardisation) who have developed a set of guidelines and quality systems to ensure reliable test results – ISO 15189:2012.
About ISO 15189:2012
ISO 15189:2012 was designed to outline the “requirements for competence and quality that are particular to medical laboratories”. Laboratory competence and quality are critical in patient diagnosis and care to ensure they meet the need of the clinicians & patients. Gaining accreditation to ISO 15189:2012 will assure clinicians employing your services that they will be benefitting from accurate results which have been measured against a consistent standard. You could benefit too from cost savings and enhanced end-user satisfaction.
Gaining Accreditation
ISO 15189:2012 divides the quality requirements of the laboratory into two distinct areas; Internal Quality Control (IQC) and External Quality Assessment (EQA). By combining both you can comprehensively review and monitor the overall performance of your laboratory, including personnel, equipment, and procedures.
A particular requirement of ISO 15189:2012 is:
“Laboratories accredited according to ISO 15189 that have two or more analysers for examinations, should have a defined mechanism for comparison of results across analysers”
How Randox can help labs with multiple instruments?

The Randox Acusera Urinalysis Quality Control is designed primarily to ensure accurate test system performance however offer the laboratory additional benefits that will help them to meet regulatory requirements whilst also reducing costs and time.
Background
It is estimated that 1 in 2 people will be affected by a urological condition at some point in their lifetime. Conditions and diseases related to kidneys, bladder and prostate, among others, are commonplace and can be devastating for millions of men, women and children across the globe.
Urological conditions can be common, such as urinary tract infections, or they can be much more serious, for example, prostate or testicular cancer.
Urinalysis is used as a screening or diagnostic tool because it can detect kidney and metabolic disorders. Often, substances such as glucose or protein will appear in the urine before a patient is aware that they have a problem. In some conditions, urinalysis also provides an easy and economical test to track patient progress, for example, if you want to know if a condition is improving.
