Hepatitis A Blood Test
The Hepatitis A Blood Test is a laboratory test that detects the presence of the Hepatitis A virus (HAV) antibodies in your blood, to confirm the state of infection.

Who is this for?
Hepatitis A Antibodies IgG & IgM
Hepatitis A antibodies are proteins that the body produces in response to the hepatitis A virus. There are two types of hepatitis A antibodies: IgG and IgM.
IgG antibodies are the most common type of hepatitis A antibody. They develop after a person has been infected with the virus and typically remain in the body for life. IgG antibodies provide protection against future infection with the virus.
IgM antibodies are less common than IgG antibodies. They develop early on during an infection and typically disappear within six months. However, some people may continue to produce low levels of IgM antibodies for up to a year after infection.
Both IgG and IgM antibodies can be detected through a blood test. A positive result indicates that a person has been exposed to the hepatitis A virus at some point in their life.
Hepatitis A antibodies are important for two main reasons. First, they can be used to diagnose an infection with the virus. Second, they can be used to determine if a person is immune to the virus.
If you have been exposed to the hepatitis A virus, it is important to get tested for hepatitis A antibodies. This will help your doctor determine the best course of treatment and protect you from future infections.
Symptoms of Hepatitis A include:
- Jaundice (yellowing of the skin and eyes)
- Dark urine
- Abdominal pain
- Loss of appetite
If you experience any of these symptoms, it is important to see a doctor right away. Hepatitis A can be a serious infection, so early diagnosis and treatment are essential.
Why might I need a hepatitis A blood test?
You may need a hepatitis A blood test if you have symptoms of hepatitis A, such as jaundice (yellowing of the skin and eyes), dark urine, light-coloured stools, nausea, vomiting, diarrhoea, abdominal pain, or loss of appetite. The hepatitis A blood test may also be ordered as part of a routine health check-up.
What do the results of the hepatitis A blood test mean?
HAV antibodies are produced in response to infection with the hepatitis A virus. If you have HAV antibodies in your blood, it means that you have been infected with the hepatitis A virus at some point in your life. Most people who are infected with hepatitis A virus will recover completely and will not develop any long-term health problems. However, some people may experience chronic liver disease or even death. If you have questions about the meaning of your hepatitis A blood test results, be sure to speak with your healthcare provider.
The Hepatitis A Blood Test is a simple and painless way to find out if you have been infected with the hepatitis A virus. The test can be ordered as part of a routine health check-up or if you are experiencing symptoms of hepatitis A. A sample of your blood is collected and sent to a laboratory for analysis. If you have HAV antibodies in your blood, it means that you have been infected with the hepatitis A virus at some point in your life. Most people who are infected will recover completely, but some may experience chronic liver disease or death. Talk to your healthcare provider if you have any questions about your hepatitis A blood test results.

Is this test for you?
If suspect you might have ingested food or liquid that was contaminated by faeces you should be tested for Hepatitis A immediately. Most hepatitis cases are found in countries where there is poor sanitation. There is also an increased risk of hepatitis A for men who have sex with men and those who inject drugs. If you suspect that you might have been exposed to the virus, it is important to take a test.
