Hepatitis A is a highly contagious viral infection that affects the liver. It is caused by the hepatitis A virus (HAV), which is typically transmitted through the consumption of contaminated food or water or through close personal contact with an infected individual.

The hepatitis A vaccine, commonly administered during childhood, is very effective at preventing infection. For those unsure about their vaccine status, immunity to the hepatitis A virus can be assessed with eNational’s blood test.

Who should take this test?

This test is used to assess immunity to the hepatitis A virus, either from a previous infection or vaccination. It is recommended for individuals who want to confirm their immunity to hepatitis A, especially those at higher risk of exposure or planning to travel to regions with a higher prevalence of the virus.

What is included in this test?

This blood test screens for:

• HAV IgG antibodies
• HAV IgM antibodies

This test detects total antibodies against the hepatitis A virus (HAV), but does not differentiate between IgG antibodies and IgM antibodies. It is not used to differentiate between vaccination, previously resolved infection, or active infection.

How will taking this test benefit me?

Hepatitis A is rarely life-threatening, but it can make you ill for several weeks or months. Confirming your immunity can provide peace of mind, especially ahead of travel.
