HBsAg screening involves testing for the presence of the Hepatitis B surface antigen (HBsAg) in the blood. Here’s a detailed overview:

What is HBsAg Screening?

• Purpose: HBsAg screening is used to detect current infection with the hepatitis B virus (HBV).
• Method: It involves a simple blood test to identify the presence of HBsAg, which is a protein on the surface of the HBV.

Why is HBsAg Screening Important?

• Early Detection: Helps diagnose acute or chronic hepatitis B infections.
• Prevention: Identifies individuals who may benefit from vaccination against hepatitis B.
• Monitoring: Monitors the effectiveness of treatment in individuals with chronic hepatitis B.
• Public Health: Plays a crucial role in preventing the spread of hepatitis B virus.

Who Should Get HBsAg Screening?

• High-Risk Groups: Individuals at higher risk include:
  • Healthcare workers exposed to blood or body fluids.
  • Individuals born to HBV-infected mothers.
  • People with multiple sexual partners or who engage in high-risk sexual behavior.
  • Injecting drug users who share needles.
  • People living with someone who has chronic HBV infection.
• Routine Screening: Some regions recommend routine HBsAg screening for all adults, especially in areas where HBV prevalence is high.
