Hepatitis B Surface Antigen CLIA Blood Test is used to detect the presence of Hepatitis B surface antigen (HBsAg) in the blood. This test helps to determine whether a person has Hepatitis B infection or not.
Hepatitis B infection is an infection of the liver caused by the hepatitis B virus (HBV). This infection can spread from one person to another through contact with infected blood or body fluids. Common symptoms of this infection are dark urine, fatigue, fever, abdominal discomfort, weakness, loss of appetite, yellowing of eyes, joint and muscle pain. Symptoms usually appear about one to four months after the occurrence of infection.
Normally in most of the cases, this infection does not last for a long time. Your immune system fights it off within a few months. However, if you have it for more than six months, you are called as a carrier. Mostly, adults may recover from this infection fully within a short period of time. Infants and children are more likely to develop a long-lasting infection.
Hepatitis B virus (HBV) has proteins on its surface. These proteins are called hepatitis B surface antigens. It is found in your blood within several weeks (4 weeks) after the infection starts. Presence of hepatitis B surface antigens causes the immune system to make antibodies. Therefore the hepatitis B surface antigens are the first marker for determining the presence of Hepatitis B infection.
This test is performed to screen or diagnose the presence of Hepatitis B infection. Your doctor may ask you to perform this test if he suspects a Hepatitis B infection or if you experience any signs or symptoms of Hepatitis B infection. This test may also be recommended to individuals with severe liver disease due to the risk of developing this infection. You may be advised to perform this test if you come in contact with a person with Hepatitis B infection or if in case of a direct contact with infected blood. It is an aid that helps in the diagnosis of Hepatitis B infection.
Inform your doctor if you are on any medications, have any allergies or underlying medical conditions before your HBsAg CLIA. Your doctor will give specific instructions depending on your condition on how to prepare for HBsAg CLIA.
No specific preparation is required for this test.
The test results may be different depending on gender, age, health conditions, and other factors.
If the test results show the presence of Hepatitis B surface antigen in the blood, this may indicate that you are infected with Hepatitis B infection.
If the test results are negative, it indicates that no Hepatitis B surface antigen is found in the blood. Therefore you are very unlikely to have a Hepatitis B infection.
