From: Fluorescence polarization assay improves the rapid detection of human brucellosis in China
Interactive dot diagram of fluorescence polarization immunoassay (FPA) results for 200 confirmed (positive) cases of brucellosis and 120 control (negative) cases. n1 = 93 mP (reference standard upper limit for reagents). n2 = 88 mP (negative group maximum). n3 = 80 mP (positive group minimum). n4 = 72 mP (reference standard lower limit for reagents)
