Development of enzyme-linked immunosorbent assay for hepatitis B e antigen

Area of Science:

• Hepatitis B diagnostics
• Immunological assays
• Viral marker detection

Background:

• Hepatitis B e antigen (HBeAg) indicates infectivity and necessitates vaccination during pregnancy.
• Current sensitive HBeAg tests are often expensive, limiting accessibility in hospitals.
• A local development of an enzyme-linked immunosorbent assay (ELISA) for HBeAg and anti-HBe was deemed necessary.

Purpose of the Study:

• To develop a locally made, sensitive, and cost-effective ELISA test for Hepatitis B e antigen (HBeAg) and its antibody (anti-HBe).
• To evaluate the performance of the locally developed ELISA kit against commercially available kits.

Main Methods:

• Development of a local enzyme-linked immunosorbent assay (ELISA) for HBeAg and anti-HBe.
• Comparative analysis of the local ELISA test with Organon Teknika and Roche Diagnostic ELISA kits.
• Testing involved routine specimens and sera positive for Hepatitis B surface antigen (HBsAg).

Main Results:

• The locally developed ELISA test demonstrated high overall agreement (97.5-98.1%) with imported kits.
• The local test exhibited slightly higher sensitivity compared to commercial ELISA kits.
• The developed assay was found to be rapid, reproducible, and specific.

Conclusions:

• Successful local development of an ELISA test for HBeAg and anti-HBe provides a cost-effective and reliable diagnostic tool.
• This advancement promotes self-reliance in detecting Hepatitis B virus infectivity markers.
• The local ELISA test meets the need for sensitive and accessible HBeAg detection in healthcare settings.
