HBsAg (CLIA) Test

The HBsAg test stands for the Hepatitis B Surface Antigen Test, which is commonly performed to diagnose hepatitis B, a liver infection caused by the hepatitis B virus (HBV). Globally, hepatitis B affects a significant portion of the population, with 1 in 3 individuals affected and 300 million people currently living with chronic infection. Due to the high number of deaths associated with hepatitis B, prompt detection of the infection is crucial. The HBsAg CLIA (chemiluminescence immunoassay analyzer) test screens for the presence of a protein (Hepatitis B surface antigen) related to HBV in your blood sample, allowing for the early diagnosis of this life-threatening infection. The test is particularly useful to detect whether you have an acute (recent) or chronic (long-standing) infection. HBV, one of the five hepatitis viruses (A, B, C, D, and E), spreads through blood, vaginal secretions, and seminal fluid. Symptoms of hepatitis B can take several months to develop after infection. In most cases, the virus may clear up from the body within six months. However, a small percentage of adults and a higher percentage of children, especially newborns, may develop chronic infections, which can result in liver damage, fibrosis (formation of scar tissue in the liver), cirrhosis (severe scarring of the liver that impairs its function), or liver cancer., you can conveniently undergo the HBsAg test at home with Sun Pathology, ensuring timely and accurate results from the comfort of your home. Early detection through the HBsAg test is essential for initiating treatment and preventing the spread of hepatitis B.

What the 1 parameters cover

Typical reference ranges — your report marks anything outside them:

The HBsAg CLIA test is essential if your healthcare provider suspects you have a liver infection caused by HBV. It is particularly needed if you exhibit symptoms of hepatitis B, which often develop gradually and might not appear until the infection becomes severe or chronic. Many individuals either show no symptoms or experience mild flu-like symptoms. Common symptoms include: Extreme fatigue Nausea Loss of appetite Muscle aches Fever Jaundice (yellowing of the skin and eyes) Dark urine Abdominal pain Swelling and confusion (in severe cases) The test is also crucial if an individual has risk factors for hepatitis B infection, such as: Being born to a mother with the virus Sexual contact with a person infected with HBV Sharing needles for intravenous drug use Living with an HBV-infected individual. Working in a healthcare setting with exposure to blood

Understanding your report

What your results can mean — always review them with your doctor:

Understanding your HBsAg blood test results is crucial for determining your health status and the next steps in your care. Interpretation of the test results can be done as follows: *A negative test result does not guarantee the absence of exposure to or infection with the hepatitis B virus. HBsAg levels may be undetectable in both early and late stages of infection.
