Aim of College of American Pathologists (CAP) Accreditation & Proficiency Testing (PT)

When hospital and reference laboratories[1] achieved CAP accreditation, they are being recognized as high quality[2] by being able to produce accurate patient results by constantly assessing their performance through PT[1] and provide patient care at lowest possible cost[2].

PT assesses the accuracy of results and is part of quality control[3]. Participating laboratories report results to CAP for assessment after carrying out necessary tests on blind samples of unknown values given to them[1]. PT results obtained allow detection of analytical, clerical and interpretation errors and they must be investigated and documented[3]. A target standard deviation index (SDI) of 0 is desired.
