SUMMARY AND PRINCIPLE OF THE TEST

Hepatitis B is an infectious illness caused by hepatitis B virus (HBV) which infects the liver ofhominoidea, including humans, and causes an inflammationcalled hepatitis. HBV is excreted in body fluids such as semen, saliva, blood and urine in persons with acute or chronic infection. The hepatitis B virus is known as a blood-borne virus because it is transmitted from one person to another via blood or fluids contaminated with blood.

About 7.*8% carry hepatitis B Virus surface antigen. About *3 million people are chronic carriers of HBV among which about *0 million are suffering Hepatitis B around the country. Transmission of hepatitis B virus results from exposure to infectious blood or body fluids.

When HBV invades the body it causes liver damage through induction of auto-immunity. Three immunity has been found, surface antigen (HBsAg)/HBsAb, core antigen (HBcAg)/HBcAb and e antigen(HBeAg)/HBeAb. As it is difficult to detect the core antigen in the serum, the other five are been done to diagnosing HBV. The surface antigen contains the determinant “a”, common to all known viral subtypes and immunologically distinguished in two distinct subgroups (ay and ad). HBV has *0 major serotypes and four HBsAg subtypes have been recognized (adw, ady, ayw, and ayr). HBsAg can be detected 2 to 4 weeks before the ALT levels become abnormal and 3 to 5 weeks before symptoms develop. The serological detection of HBsAg is a powerful method for the diagnosis and prevention of HBV infection and ELISA has become an extensively used analytical system for screening of blood donors and clinical diagnosis of HBV in infected individuals

SPECIMEN COLLECTION AND PREPARATION

Serum should be prepared from a whole blood specimen obtained by acceptable medical techniques. Either serum or plasma can be used in this test.  Remove serum or plasma from the clot or blood cells as soon as possible to avoid hemolysis.  Specimen with extensive particulate should be clarified by centrifugation prior to use.  Specimen frozen at **0°C or colder may be used.  Avoid repeated freeze thaw.

STORAGE OF TEST KITS

Unopened test kits should be stored at **8°C. DO NOT FREEZE KIT COMPONNETS.  The microtiter plate should be kept in a sealed bag to minimize exposure to damp air. Use up the reagents as soon as possible after the kit is unpacked.
