Hepatitis A Virus Tests: About Your Child's Tests

What are hepatitis A tests?

Hepatitis A virus tests are blood tests that check for a substance (antibodies) in your child's blood. They show whether your child has hepatitis A now or had it in the past. The tests also can show if your child is protected from getting the disease.

Why are these tests done?

Your child may need these tests if:

• He or she has symptoms of hepatitis.
• He or she may have been exposed to the hepatitis A virus. Children have a greater chance of being exposed to the virus if:
  • They have been to a country where the disease is common.
  • They have not been vaccinated for hepatitis A.
  • They live with someone who has the disease.
• Your child had other tests that show signs of liver problems.
• You or your doctor wants to know if your child is protected from getting the disease.

How do you prepare for the tests?

You don't need to do anything before your child has these tests.

How is the test done?

A health professional uses a needle to take a blood sample, usually from the arm.

What happens after the tests?

Your child will probably be able to go home right away. And your child can go back to their usual activities right away.
