    2019-3-28 · Background: Hepatitis is an inflammatory condition of the liver and viral hepatitis is a conventional term used to denote hepatitis caused by hepatotrophic viruses (Hepatitis A-G). High prevalence of these viruses are reported in Nigeria. Hepatitis B and C may cause liver cirrhosis and they can be contacted through contaminated blood and blood products. Many blood banks in Nigeria screen for hepatitis B and C using immune-chromatographic screening method (Rapid test strip). This is because these strips are readily available in the market, cheap, requires no electricity for storage, special training or equipment before use. The intent of our study is to compare the sensitivity of this method using an advanced immunological method.

    Hepatitis B Screening. Hepatitis B virus (HBV) antigens are proteins that appear in different areas of the virus. HBV has three antigens (surface, core, and e), some of which can be detected in the blood. The body’s immune response produces antibodies tailored to each type of antigen (surface antibody, core antibody, and e antibody), which can also be detected from a blood test.
