The iCARE One Step HBsAg Test is a colloidal gold enhancedimmunoassay for the determination of HBV surface antigen (HBsAg)in human whole blood, serum or plasma. Goat anti‐HBsAg antibodyis immobilized in the test region on nitrocellulose membrane. Duringthe assay specimen is allowed to react with the colored conjugate(antibody‐colloidal gold conjugate); the mixture then migrateschromatographically on the membrane by the capillary action. AnHBsAg positive specimen produces a distinct color band in the testregion, formed by the specific antibody‐HBsAg‐colored conjugatecomplex. Absence of this colored band in the test region suggests anegative result. A colored band always appears in the control regionserving as procedural control regardless of the test result.
