HBsAg Rapid Test (Whole Blood/Serum/Plasma) is a rapid visual immunoassay for the qualitative presumptive detection of HBsAg in human whole blood, serum, or plasma specimens. This kit is intended to be used as an aid in the diagnosis of HBV infection.

Hepatitis B virus (HBV) is the prototypic member of the hepadnaviruses. In the lipid envelope of this small DNA virus the hepatitis B surface antigen (HBsAg) is located. During the replicative phase of the virus this surface antigen is produced in excess and detectable in the blood of infected person. The antigens HBcAg and HBeAg are parts of the nucleocapsid. The incubation period of HBV is 6 weeks to 6 months

The HBsAg Rapid Test (Whole Blood/Serum/Plasma) has been designed to detect the HBsAg through visual interpretation of color development in the strip. The membrane was immobilized with anti-HBsAg antibodies on the test region. During the test, the specimen is allowed to react with colored anti-HBsAg antibodies colloidal gold conjugates, which were precoated on the sample pad of the test. The mixture then moves on the membrane by a capillary action, and interact with reagents on the membrane. If there were enough HBsAg in specimens, a colored band will from at the test region of the membrane. Presence of this colored band indicates a positive result, while its absence indicates a negative result. Appearance of a colored band at the control region serves as a procedural control. This indicates that proper volume of specimen has been added and membrane wicking has occurred.
