HBsAg Rapid Test Dipstick(S / P)

【SUMMARY】
Viral hepatitis is a systemic disease primarily involving the liver. Most cases of acute viral hepatitis are caused by Hepatitis A virus, Hepatitis B virus (HBV) or Hepatitis C virus. The complex antigen found on the surface of HBV is called HBsAg. Previous designations included the Australia or Au antigen .1 The presence of HBsAg in serum or plasma is an indication of an active Hepatitis B infection, either acute or chronic. In a typical Hepatitis B infection, HBsAg will be detected 2 to 4 weeks before the ALT level becomes abnormal and 3 to 5 weeks before symptoms or jaundice develop. 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.

The HBsAg Rapid Test Dipstick is a rapid test to qualitatively detect the presence of HBsAg in serum or plasma specimen. The test utilizes a combination of monoclonal and polyclonal antibodies to selectively detect elevated levels of HBsAg in serum or plasma.

【DIRECTIONS FOR USE】
1. Remove the test dipstick from the sealed foil pouch and use it as soon as possible. Best results will be obtained if the assay is performed immediately after opening the foil pouch.
2. For Serum or Plasma specimen:
With arrows towards pointing toward serum or plasma specimen, immerse the test Dipstick vertically in the serum or plasma for at least 10-15 seconds. Do not pass the maximum line (MAX) on the test Dipstick when immersing the Dipstick. See illustration below.
3. Place the Dipstick on a non-absorbent flat surface, start the timer and wait for the color line (s) to appear. The result should be read at 15 minutes.
Note: A low HBsAg concentration might result in a weak line appearing in the test region (T) after an extended period of time; therefore, do not interpret the result after 30 minutes.
