proficiency testing schemes

Proficiency testing schemes are organized evaluations where laboratories or testing facilities analyze the same samples to assess their accuracy and consistency. By comparing results across different labs, these schemes help identify strengths and weaknesses in testing processes, ensuring reliable and standardized results. They are essential for maintaining quality, compliance with regulations, and improving overall testing performance. Essentially, it's a quality check for labs, confirming they produce trustworthy results comparable to others in the field.
