Intented Use:
Compass CLEAR PATH ™ HBsAg Rapid Card Test is a lateral flow chromatographic immunoassay for the qualitative detection of Hepatitis B surface antigen (HBsAg) in human serum/plasma/whole blood to aid in the diagnosis of infection with hepatitis-B virus.
Test Principal:
HBsAg Rapid Card Test is a lateral flow chromatographic immunoassay. The test cassette consists of a coated conjugate pad containing anti-HBsAg antibody conjugated with colloidal gold (HBsAg Ab conjugates) and a control antibody conjugated with colloidal gold, and a nitrocellulose membrane strip containing a test line (T line) and a control line (C line). The T line is pre-coated with non-conjugated HBsAg antibody, and the C line is pre-coated with a control line antibody. When an adequate volume of test specimen is dispensed into the sample well of the cassette, the specimen migrates by capillary action across the test cassette.
HBsAg, if present in the specimen, will bind to the HBsAg Ab conjugates. The immunocomplex is then captured on the membrane by the pre- coated non-conjugated HBsAg antibody forming a burgundy-colored T line, indicating a HBsAg positive test result. Absence of the T line suggests a negative result. The control line acts as a procedural control. Control line should always appear if the test is performed as per the procedure. If the C line does not develop, the test result is invalid.
