The HBsAg Test at Pamel Laboratories is a screening test for Hepatitis B, used to detect the presence of the Hepatitis B surface antigen (HBsAg) in the blood. A positive result indicates that a person is currently infected with the Hepatitis B virus (HBV), either in the acute or chronic phase of the infection, and may be capable of transmitting the virus to others.
This test is essential for blood donation screening, antenatal care, pre-surgical evaluations, and general liver health assessments.
What the Test Detects:
-
HBsAg (Hepatitis B surface antigen) – the first detectable sign of active Hepatitis B infection
-
A positive result means the person is infected and contagious
-
A negative result means no current infection, but does not rule out previous exposure
Purpose of the Test:
-
Screen for active Hepatitis B infection
-
Part of routine antenatal screening
-
Required before blood transfusion, organ donation, or surgery
-
Monitor liver function and viral load in known hepatitis cases
-
Identify chronic carriers of Hepatitis B
Sample Type: Blood sample (serum)
Turnaround Time: Same day (within a few hours)
Important Notes:
-
A positive result may require further testing (e.g., HBV DNA, HBeAg, liver function tests)
-
Individuals who test positive should avoid sharing personal items, and seek medical care for follow-up
-
The test does not differentiate between acute and chronic infections
