INTENDED USE

Hepatitis B Surface Antigen (HBsAg) Rapid Tesk Dipstick (Whole Blood/serum/plasma) is a rapid chromatographic immunoassay for the qualitative detection of Hepatitis B Surface Antigen in whole blood , serum and plasma.

SUMMARY

Hepatitis is inflammation of the liver tissue. The most common cause worldwide is viruses.Most cases of acute viral hepatitis are caused by Hepatitis A virus, Hepatitis B virus (HBV) or Hepatitis C virus. Hepatitis B is transmitted through contact with infectious body fluids, such as blood, vaginal secretions, or semen, containing the hepatitis B virus (HBV). Injection drug use, having sex with an infected partner, or sharing razors with an infected person increase your risk of getting hepatitis B. Hepatitis B surface antigens can be found in your blood within several weeks (2 to 4 weeks) after the infection starts. They are one of the earliest signs of a hepatitis B infection.The presence of HBsAg in (WB/S/P) is an indication of an active Hepatitis B infection, either acute or chronic. HBsAg has four principal subtypes: adw, ayw, adr and ayr. Because of antigenic heterogeneity of the determinant, there are 10 major serotypes of Hepatitis B virus.
Atlas HBsAg Hepatitis B Surface Antigen Rapid Tesk Dipstick is a rapid test to qualitatively detect the presence of HBsAg in Whole Blood/serum/plasma specimen. The test utilizes a combination of monoclonal and polyclonal antibodies to selectively detect elevated levels of HBsAg in whole blood, serum and plasma.

PRINCIPLE

Hepatitis B Surface Antigen Rapid Tesk Dipstick is a qualitative, solid phase, two-site sandwich immunoassay for the detection of HBsAg in whole blood/serum /plasma. The membrane is pre-coated with anti-HBsAg antibodies on the test line region of the Device. During testing, the specimen reacts with the particle coated with anti-HBsAg antibodies. The mixture migrates upward on the membrane chromatographically by capillary action to react with anti-HBsAg antibodies on the membrane and generate a colored line. The presence of this colored line in the test region indicates a positive result, while its absence indicates a negative result. To serve as a procedural control, a colored line will always appear in the control line region indicating that proper volume of specimen has been added and membrane wicking has occurred.
