Product Description

HEPAVIEW – one step test for HBsAg is a rapid, qualitative, two site sandwich immunoassay for the detection of Hepatitis B surface antigen, a marker for Hepatitis B infections, in serum/plasma specimen. Blood containing the Hepatitis B Virus (HBV) is potentially infectious. Hepatitis B surface antigen (HBsAg), earlier known as Austrailia antigen is among the first serological markers that circulate in the blood of infected persons even two to three weeks prior to appearance of clinical symptoms. The levels of HBsAg are especially elevated during the symptomatic phase and decline thereafter. Detection of HBV using HBsAg as a marker to screen blood donors is essential to reduce the risk of transmission of Hepatitis B by blood transfusion. HBsAg detection is also useful for screening high risk groups for HBV and for differential diagnosis of Hepatitis infection. HEPAVIEW – one step test for HBsAg detects the presence of HBsAg in serum/plasma specimens, qualitatively, at concentrations as low as 0.5 ng/ml. HEPAVIEW – one step test for HBsAg utilizes the principle of agglutination of antibodies/ antisera with respective antigen in immuno-chromatography format along with use of nano gold particles as agglutination revealing agent. As the test sample flows through the membrane assembly of the device after addition of the clearing buffer, the colored colloidal gold conjugate of the Agglutinating Sera for HBsAg complexes with the HBsAg in the sample. This complex moves further on the membrane to the test region where it is immobilized by another Agglutinating Sera for HBsAg coated on the membrane leading to formation of a pink-purple coloured band which confirms a positive test result. Absence of this coloured band in the test region indicates a negative test result.
