Hepatitis B & C

About the Tests

There is no swabbing involved, the Hepatitis B and C test only requires a single blood sample.

The test for Hepatitis B detects the presence of Hepatitis B antibodies which are produced in response to exposure to the virus and found in the blood of someone who is infected. This test is selected as it is able to identify the presence of a Hepatitis B infection before symptoms appear.

The test for Hepatitis C detects the presence of the protein that immune systems make in response to the Hepatitis C virus.

How to Prepare for the Test

You do not need to fast before the test.

Possible Outcomes


A normal test result means that there is no evidence of either infection at the time of the test. Antibodies can take between three to six months to develop in the blood, so if testing for a specific incident, initial tests may be negative if they are inside this window - read more about 'testing windows'.

It is important for those who are at increased risk of infection to have screening tests performed on a regular basis to check for possible exposure. Increased risk would include any sexual encounter with a partner whose STI status is unknown.


An abnormal result for either of these tests will mean a diagnosis of Hepatitis B or C infection, or both.

Hepatitis B is treatable and in most cases can be cured. A treatment plan for Hepatitis B should be developed by a doctor and will usually involve bed rest and fluids.

Hepatitis C is also treatable and curable, and is usually best managed with a healthy diet, fluids and rest.

Who Should Have This Test?

The test for Hepatitis B and C is recommended for those who believe they may have been exposed to either or both of these infections.

For anyone who has had a recent sexual encounter with an individual whose STI status is unknown, we recommend the more comprehensive ‘Routine Screen’, which tests for the presence of six of the most common STIs that are detectable through blood and urine analysis.

When to Have This Test?

If you are concerned about a sexual encounter with a partner whose STI status is unknown, please use the 'window period' guidelines to determine when you should be tested (the 'window period' is time during which an infection has been passed, but may be undetectable - so even though it may be present it cannot be diagnosed).

If you've been notified or are concerned about exposure to Hepatitis B or C, we suggest that you stop engaging in sexual activity and see a doctor as soon as possible.


Recent HIV and Hepatitis B Exposure

If you believe you have been exposed to HIV or Hepatitis B in the last 72 hours you should stop engaging in sexual activity and immediately see a doctor, hospital or specialised clinic in order to receive preventive post-exposure treatment (PEP). Click here to learn more about PEP.


If you have genital, oral or anal symptoms such as sores, rashes, lumps, itching, unusual discharge or bleeding, discomfort when urinating, lower pain or a sense of general un-wellness, it is important that you stop engaging in sexual activity and see a doctor as soon as possible.
