Understand more about Hepatitis B s (Surface) Antigen

Hepatitis B virus is one of five main hepatitis viruses, referred to as types A, B, C, D and E and is the causative agent of Hepatitis B (infection in the liver). Hepatitis B Surface Antigen (HBsAg) is present on the surface of the Hepatitis B virus (HBV). HBsAg is present in the blood of patients with viral hepatitis B (with or without clinical symptoms).

HBsAg is the first marker appearing in the blood at 6 to 16 weeks following exposure to HBV. In most cases after an acute infection, this virus clears up on its own in 1 to 2 months after the onset of symptoms. but in some people, the virus does not go away and results in chronic infection which over the years may lead to liver damage (scarring or cirrhosis) or liver cancer. Persistence of HBsAg for more than 6 months in duration indicates the development of either a chronic carrier state or chronic HBV infection.



What Results of Hepatitis B s (Surface) Antigen mean?

A "Reactive" or "Positive" HBsAg test result means that the person is infected with Hepatitis B virus. If a person tests “positive,” then further testing is required to determine if this is a new “acute” infection or a “chronic” Hepatitis B infection or chronic HBV carrier state.

A "Non-reactive" or "Negative" HBsAg test result means that the person is not infected with Hepatitis B virus.



Patient Concerns about Hepatitis B s (Surface) Antigen

Frequently Asked Questions about Hepatitis B s (Surface) Antigen

Q. How is this test performed?
This test is performed on a blood sample. A syringe with a fine needle attached is used to withdraw blood sample from a blood vessel in your arm generally from the inner side of the elbow area. The doctor, nurse or the phlebotomist will tie an elastic band around your arm which will help the blood vessels to swell with blood and hence makes it easier to withdraw blood. You may be asked to tightly clench your fist. Once the veins are clearly visible, the area is cleaned with an antiseptic solution and then the needle is inserted into the blood vessel to collect the sample. You may feel a tiny pinprick during the procedure. Blood sample once collected is then sent to the laboratory.
Q. Is there any risk associated with this test?
There is no risk associated with the test. However, as this test involves a needle prick to withdraw the blood sample, rarely, a patient may experience increased bleeding, hematoma (blood collection under the skin) formation, bruising or infection at the site of needle prick.
