Proficiency testing (PT)
A quality assurance mechanism in which laboratories analyse blind samples distributed by an external scheme coordinator and have their results compared against consensus or known-reference values. For F/A/E laboratories, CTS fire debris PT, ENFSI EWG PT, and CTS explosives PT are the principal schemes.
