Proficiency Testing: reliability for the analytical performance of laboratories

Far beyond the legislative obligation, Proficiency Testing is essential in the process of continuous improvement of the laboratory

Looking for a new path in the day-to-day improvement decisions within the laboratory is considered a fundamental strategy for growth, recognition and excellence in laboratory analysis.

In this sense, one of the main tools that leverage the strategies, is the participation in Proficiency Testing Programs (EP), also known as External Quality Control. The main characteristic of the Program is to indicate the analytical accuracy of the laboratory. The tool is efficient for evaluating the technical quality and to guarantee the reliability of the results.

Moreover, the Program guarantees market comparison and the identification of trends that are not perceived otherwise. The Proficiency Testing is responsible for taking important information to the routine of laboratories, such as: identifying failures and enabling corrective or preventive actions to be taken.

The laboratory that joins the participation in a proficiency program finds in the solution the continuous improvement of its process, and not only the fulfillment of a legal requirement. This is because the EP is a regular external evaluation, which compares the performance of the participant with laboratories of similar systems, providing information about the performance of the analytical methods.

Furthermore, it allows obtaining guidance on problems and pointing to analytical solutions, provided that the laboratory has the ability to interpret and use the data provided by the provider.

Practice Proficiency Testing

It is a fact that the laboratories will occasionally present unsatisfactory results, due to the variation that is characteristic of the analysis process. However, the demand for EP occurs precisely so that variations are minimized, keeping them under control so as not to impact the results of the routine.

To ensure a better use of the benefits that the EP can provide, it is important that the results are analyzed and that the laboratory seeks to identify the causes of the observed deviations. Discarding the possibility of “coarse” errors (incorrect transcription of results, inadequate selection of the analytical system or failure to follow the procedure), it is important to check the steps of the process that may be related to the failures observed in the EP.

Laboratories that analyze their reports, observing trends and improvements, have a notable evolution in the analytical routine, obtaining quality services and providing security to citizens. Consequently, these laboratories remain competitive and sustainable.

By adopting this practice in its routine, the laboratory already fulfills the necessary requirement for laboratory accreditation processes (ISO 15189, ISO 17025, PALC-SBPC/ML, DICQ-SBAC, etc.) and regulatory bodies.

PRM 0009

Accreditation Cgcre/Inmetro - Certified Reference Material Producer

Controllab has been accredited as a Certified Reference Material Producer (MRC) since 2016 by Inmetro’s General Coordination for Accreditation (CGCRE), under the PMR 0009 number. The assessment of this conformity is carried out according to the requirements established in ABNT NBR standards ISO 17034 and Inmetro, thus ensuring competence for the production of MRCs, according to the Scope of Accreditation.

CAL 0214

Accreditation Cgcre/Inmetro - Calibration Laboratory

In December 2002, the Calibration Laboratory was accredited by Inmetro’s General Coordination for Accreditation (CGCRE). With this recognition, it became an integral part of the Brazilian network of accredited laboratories, under nº214. Since then, it is periodically evaluated for the maintenance and/or extension of accreditation.

PEP 0003

Accreditation Cgcre/Inmetro - Control Laboratory

In September 2011, Controllab was accredited by Inmetro’s General Coordination for Accreditation (CGCRE) as a proficiency test provider, under nº PEP0003. Initially as part of a pilot project by Inmetro, this accreditation was based on ILAC G13: 2007 and included several clinical and hemotherapy tests. In the periodic evaluations of this accreditation, new segments and tests are included and the evaluation is now conducted according to ABNT NBR ISO/IEC 17043.

This accreditation attests to Controllab’s technical competence to develop and conduct proficiency tests in accordance with international requirements and enables it to be recognized in other countries, in accordance with mutual recognition agreements signed by Brazil in Mercosur, the Americas and Europe.
