Abstract:

Cut-off value is important for determining the results of qualitative determinations for infectious disease screen. However,there are no recommendations on whether cut-off value verification is necessary and how to verify it. This review comprehensively analyzes the performance verification relevant standards,guidelines and literatures,and discussed the significance of cut-off value verification of infectious disease screen items and the feasibility of verification scheme,in order to provide a reference for clinical laboratories.

Key words: Infectious disease screening, Cut-off value, Qualitative determination, Performance verification
