Interlaboratory comparative tests are an important tool for ensuring the quality and reliability of laboratory test results. They contribute to checking the qualifications of laboratories and improving their competence.
What are interlaboratory comparative tests?
Interlaboratory comparison tests provide for simultaneous testing by several laboratories to compare their results. This allows you to identify possible deviations and accuracy of measurements. Conducting such tests is carried out in accordance with the ISO 17043 standard, which defines general requirements for the competence of providers of qualification verification.
The importance of comparative tests
Comparative tests are necessary to confirm the accuracy and reliability of laboratory results. They help identify system errors and increase the level of quality and accuracy of research. Laboratories that regularly participate in PC demonstrate competence and reliability to clients and regulatory authorities.
Standardization and qualification verification
An important aspect of interlaboratory comparative tests is the standardization of measurement methods. The use of standardized methods ensures comparability of results between different laboratories. Testing the qualifications of laboratories helps confirm their ability to conduct accurate and reliable tests in accordance with ISO 17043 standards.
Qualification verification procedure
Conducting interlaboratory comparative tests includes several stages:
- Preparation: determination of test parameters and selection of control materials.
- Testing: simultaneous testing in different laboratories.
- Analysis of results: Comparison of test results and identification of possible deviations.
- Report: Preparation of a report on test results and recommendations for improvement.
Advantages for laboratories
Participation in interlaboratory comparative tests provides laboratories with a number of advantages:
- Confirmation of competence: PCs allow to confirm the qualification of the laboratory to clients and regulatory authorities.
- Quality improvement: analysis of test results helps identify and correct system errors.
- Reduction of costs: Timely detection of deviations allows to reduce the costs of repeated tests and corrective measures.
Interlaboratory comparison tests are an important tool for ensuring the quality and reliability of laboratory tests. They contribute to checking the qualifications of laboratories and increasing their competence, which is an important factor in successful accreditation and trust on the part of clients.
