Proficiency testing (PT): The tool in quality assurance of testing laboratories

Abstract

The proficiency testing (PT) is the ideal approach for the assessment of laboratory efficiency by evaluating their results by using external resources. The foremost objective of PT is to examine the accuracy of the results attained by a laboratory and which allows the laboratory to determine their gross errors and eventually overcome the incorrect procedures. Therefore, proficiency testing is the tool for quality assurance of the laboratories. Apart from this, laboratories are required to participate in a proficiency test scheme to obtain the scores and reduce notable inaccuracies of the laboratory by documenting.
