LOINC description : Hepatitis B surface antigen (HBsAg) rapid tests are available in test strip and cassette
formats from manufacturers in various countries including the US, Singapore, and China.
(As of 8/25/2014, no HBsAg rapid test kits are approved for use in the United States).
Hepatitis B surface antigen (HBsAg) rapid tests are intended to be used for screening
patients for hepatitis B infection and for screening blood donors and blood products.
HBsAg is the first serologic marker to appear in the blood of patients infected with
hepatitis B, prior to the onset of symptoms. HBsAg can be detected 2-4 weeks in advance
of alanine aminotransferase (ALT) liver enzyme levels becoming increased, and 3-5
weeks prior to symptoms. This makes HBsAg rapid tests particularly useful for screening.
Follow-up and supplementary testing of any positive samples with other analytical
methods (e.g. ELISA, WB)are required however, and negative results do not exclude
Hepatitis B virus (HBV) exposure or infection. This term was created for, but not
limited in use to, the OneStep HBsAG RapiCard InstaTest kit which uses a chromatographic
lateral flow device technique on whole blood, serum, or plasma. Test cassette must
be at room temperature prior to testing and then results can be read within 15 minutes.;
