Serum HBsAg Test at Chughtai Lab

The Serum HBsAg (Hepatitis B Surface Antigen) test is a blood test used to detect the presence of the Hepatitis B virus (HBV) in the body. HBsAg is a protein found on the surface of the Hepatitis B virus and is one of the earliest markers of infection. Detecting HBsAg in the blood indicates that a person has a current Hepatitis B infection, which may be acute (recent) or chronic (long-term). This test is widely used for screening, diagnosis, and monitoring of Hepatitis B virus infection.

Hepatitis B is a viral infection that primarily affects the liver and can lead to serious complications such as chronic hepatitis, liver cirrhosis, liver failure, and hepatocellular carcinoma (liver cancer) if left untreated. Since many infected individuals may have no symptoms during the early stages, timely screening is essential for early diagnosis, treatment, and prevention of transmission.

Doctors commonly recommend a Serum HBsAg test for individuals with abnormal liver function tests, pregnant women during routine antenatal screening, healthcare workers, blood donors, people with a family history of Hepatitis B, patients undergoing dialysis, individuals with high-risk exposure, and those experiencing symptoms such as jaundice, fatigue, abdominal pain, dark urine, nausea, or loss of appetite.

At Chughtai Lab, the Serum HBsAg test is performed using advanced immunoassay technology to ensure highly accurate and reliable results. Supported by experienced laboratory professionals, qualified pathologists, and stringent quality assurance protocols, Chughtai Lab provides trusted Hepatitis B screening services through its nationwide network of collection centers across Pakistan.

High-Risk Exposure Assessment

Individuals with occupational exposure, household contact with infected persons, dialysis patients, or those with other HBV risk factors may require HBsAg screening.

Serum HBsAg Reference Interpretation

Result	Interpretation	Clinical Significance
Non-Reactive (Negative)	HBsAg Not Detected	No laboratory evidence of a current Hepatitis B infection. If recent exposure is suspected, repeat testing may be recommended after the window period.
Reactive (Positive)	HBsAg Detected	Indicates a current Hepatitis B virus infection (acute or chronic). Additional tests such as HBV DNA (PCR), HBeAg, Anti-HBs, and Anti-HBc may be recommended to assess the stage of infection and guide treatment decisions.

Note: A reactive HBsAg result should always be confirmed and interpreted by a qualified healthcare professional in conjunction with the patient’s medical history, liver function tests, and additional Hepatitis B investigations.
