Profeciency testing and international comparison

SNAS assesses the fulfillment of requirements of the standards ISO/IEC 17025 for

testing and calibration laboratories, ISO 15189 for medical laboratories and

these standards require that laboratories shall have a system for assurance

of quality of test and/or calibration results and medical examination within this system they participate in proficiency testing (external quality assessment) or in other interlaboratory comparisons.

Proficiency tests and interlaboratory comparisons are an important tool for monitoring of laboratory performance. SNAS considers the participation of laboratories in the PT and ILC programs as an important part of demonstrating the fulfillment of the accreditation criteria of accredited laboratories.

SNAS requires the active participation of laboratories in PT/ILC programs organized in Slovakia or at the international level in accordance with the relevant EA and SNAS regulations. The participation of laboratories in PT and ILC is governed by the SNAS policy for participation in proficiency tests PL-23 and the methodological guideline for determination of the level and frequency of the participation in proficiency testing MSA-L/14.

If PT/ILC is not available (practicable), the laboratory must ensure quality control by other adequate procedures (MSA-L/14 and PL23).

Calibration, testing and medical laboratories are obliged to insert the current version of the implementation of the participation strategy in PT /ILC in the completed relevant form TL 71 before each assessment into AIS, in the section Documentation, PT/annual analyses.
