What is ISO/TS 20914 - Guidance for the estimation of measurement uncertainty in medical laboratories about?

ISO/TS 20914 discusses guidance for medical laboratories. ISO/TS 20914 is an international standard that provides practical guidance for the estimation of measurement uncertainty in medical laboratories.

ISO/TS 20914 provides practical guidance for the estimation and expression of the measurement uncertainty (MU) of quantitative measurand values produced by medical laboratories. Quantitative measurand values produced near the medical decision threshold by point-of-care testing systems are also included in ISO/TS 20914.

ISO/TS 20914 also applies to the estimation of MU for results produced by qualitative (nominal) methods which include a measurement step.

ISO/TS 20914 encourages you to achieve standardization among medical laboratories.

Note: It is not recommended that estimates of MU be routinely reported with patient test results but should be available on request.

Who is ISO/TS 20914 - Guidance for the estimation of measurement uncertainty in medical laboratories for?

ISO/TS 20914 on guidance for the estimation of measurement uncertainty in medical laboratories is useful for:

• Medical laboratories
• Healthcare providers

Why should you use ISO/TS 20914 - Guidance for the estimation of measurement uncertainty in medical laboratories?

Improved standardization and harmonization of medical laboratory practices worldwide benefits society as patients and healthcare professionals increasingly move within and between healthcare services in the global economy.

ISO/TS 20914 guideline assist you with measurement uncertainty for medical laboratories and steps for estimating the uncertainty of measurand values.

For medical laboratories and healthcare providers, measurement uncertainty (MU) estimates indicate that multiple values are possible for a given measurement, provide evidence that the term ‘true value’ of a quantity is a theoretical concept, quantify the quality of a result relative to its suitability for use in making medical decisions, allow the combination with other sources of uncertainty, support interpretation of patient results close to medical decision limits, etc.

ISO/TS 20914 ensures that measurement results are useful and safe in medical practice and permits meaningful comparison with medical decision limits and previous results of the same kind in the same individual.
