HBsAg Test kit (Colloidal Gold) is used for qualitative detection of Hepatitis B surface Antigen in human serum or plasma samples. Hepatitis B surface Antigen (HBsAg) is the hepatitis b virus coat protein. It's not contagious, only the antigenicity. But it is usually accompanied by the presence of hepatitis b virus, so it is a sign of the hepatitis b virus infection.
[Test principle]
HBsAg Test kit (Colloidal Gold) uses colloidal gold immune chromatography technology to qualitative detection of Hepatitis B surface Antigen in human serum or plasma samples.
The sample is dripped into the sample well and chromatographed under the capillary action. If there is HBsAg in the sample, the HBsAg in the sample will combine with gold-labeled HBsAg recombinant antibody to form a gold-labeled complex. The complex continued to move forward and specifically bound to another HBsAg recombinant antibody of the detection line, and a purple-red line appeared. lf there is no HBsAg in the sample, the gold-labeled complex will not be formed, and it will not specifically bind to another HBsAg recombinant antibody immobilized at the detection line during the chromatography process, so that it can be detected during the detection process. The line is not colored.
A purple-red line appears on the control line regardless of the presence or absence of HBsAg in the sample. If the control line is not colored, it means that the test result is invalid regardless of whether the test line is colored. The control line is the criterion for judging whether the test strip is valid.
