HBV Immunity Profile

HBV Immunity Profile measures several markers in the blood that show whether you are infected with the hepatitis B virus. These markers include surface antigen, core antibody, and surface antibody.

• To detect whether you have been exposed to the hepatitis B virus
• To evaluate the effectiveness of previous or ongoing treatment for hepatitis B
• To determine whether you need to get vaccinated against hepatitis B
• To assess your risk of developing liver cancer or other liver diseases

Your doctor may recommend this test if you

• have symptoms of acute or chronic liver disease, such as abdominal pain, nausea, vomiting, fatigue, or jaundice,
• have risk factors for hepatitis B, such as unprotected sex with an infected person, sharing needles or syringes with an infected person, or being born to a mother with hepatitis B, or
• want to determine your immune status and whether you need to get vaccinated against hepatitis B.

Abnormal results may indicate acute or chronic hepatitis B infection, past exposure to the virus, the presence of antibodies from vaccination or treatment, or false-positive results.

During this test, a healthcare professional will draw a sample of your blood from a vein in your arm. The sample will be sent to a laboratory for analysis.

To prepare for this test, you do not need to fast or follow any dietary restrictions. Inform your doctor if you are taking any medications, especially antiviral drugs, which can affect the test results. Also, tell them if you have any specific requirements.

• Liver function tests: These blood tests measure liver enzymes and other substances to assess liver health.
• Hepatitis B viral load test: This test measures the quantity of hepatitis B virus in your blood to monitor treatment and disease progression.

Hepatitis B is a virus that causes inflammation of the liver. Many people with hepatitis B have no symptoms, but some experience fatigue, abdominal pain, loss of appetite, and jaundice. Chronic hepatitis B can lead to liver failure, cirrhosis, and liver cancer.
