HBsAg Test

HBsAg Test is based upon the principle of immuno-chromatography, a two-site immunoassay on a nitrocellulose membrane. Each test card contains a strip composed of sample pad, conjugate pad, nitrocellulose membrane and absorbent pad. When an adequate volume of specimen is dispensed into the sample well of the test device over the sample pad, the specimen migrates immuno-chromatographically by capillary action across the nitro cellulose membrane along with complex of colloidal gold conjugate with HBsAg present in the test specimen. Appearance of pink / purple lines at test line region ‘T’ in addition to pink / purple line at control line region ‘C’, indicates that test specimen has detectable level of HBsAg. Highly sensitive, specific and reliable test, packed individually having shelf life of 24 months from date of manufacturing if stored at 2-40°C under sealed conditions away from the direct sunlight.
