What does this test do?

This test determines the total amount of antibodies to the Hepatitis A virus circulating in the bloodstream.

Why is this important?

Hepatitis is a general term that means inflammation of the liver. This condition can result from many different causes including excessive alcohol use, medications, chemicals, poisons, toxins, or by infection.

One of the organisms that can infect the liver and cause hepatitis is called Hepatitis A virus (Hep A virus). This virus is transmitted through exposure to contaminated food or water, and from close contact with a person who is carrying the infection such as sharing household items like toothbrushes.

Although millions of people around the world are infected by Hep A virus every year, its incidence in the U.S. is relatively low due to water treatment standards as well as the availability of a vaccine to the virus. Mild cases of hepatitis A don’t require any treatment except for supportive care, and most people who do become infected with Hep A virus recover completely with no permanent liver damage.

Preventing infection is still the best way to avoid complications however, and practicing good hygiene (including washing your hands frequently) is one of the best ways to protect against contracting hepatitis A.

What do the results mean?

This test does not detect the Hep A virus itself; rather it checks for the total amount of antibodies to Hep A virus. As such, this test by itself cannot be used to distinguish between someone who has an active, ongoing infection and someone who has had Hep A virus in the past. Likewise, the test does not provide any information about the duration of a particular Hep A viral infection or the amount of liver damage, if any, that may have resulted.

positive test means that your body is producing antibodies to the Hep A virus. This can result either from an infection with the Hep A virus, or in those who have been vaccinated against Hep A virus in the past. If your test is positive for antibodies and you have never received a Hepatitis A vaccination, it is vital that you follow up with your physician to discuss what steps should be taken next, if any.

It is important to note that it may take some time after exposure to Hep A virus for your body to generate antibodies to the virus. This means that even if your test result is negative, if you think you may have been recently exposed to the Hepatitis A virus then you should likewise follow up with your physician to discuss what steps should be taken next, if any.
