Interkit Reproducibility of the Indirect Immunofluorescence Assay on HEp-2 Cells Depends on the Immunofluorescence Reactivity Intensity and Pattern

Abstract

Interkit nonreproducibility in HEp-2/IFA is prevalent and occurs with the highest frequency with weakly reactive samples. International initiatives with the engagement of <i>in vitro</i> diagnostic industry are encouraged to promote the harmonization of the properties and performance of HEp-2/IFA commercial kits.
