What is a Hepatitis A Antibody?
A Hepatitis A antibody is a protein produce by your immune scheme in response to the front of the hepatitis A virus. There are two primary eccentric of antibody tested in clinical background to evaluate your status, and distinguishing between them is all-important for an exact diagnosis:
- Anti-HAV IgM: This antibody appears in the rakehell short after the initial infection. Its presence generally show an acute or recent hepatitis A infection.
- Anti-HAV IgG (Total Anti-HAV): This antibody develops later in the class of an infection or following vaccination. Its presence indicates long-term resistance. If you test confident for total anti-HAV, it means you have been reveal to the virus in the past or have been inoculate, and you are protect against next infection.
When you undergo a profligate test, the lab is appear for these mark to determine if you are currently sick, if you were chuck in the past, or if you have ne'er been divulge to the virus at all.

| Total Anti-HAV (IgG) Positive | Immune/Protected | The person has had a past infection or has been amply inoculate. |
| Full Anti-HAV Negative | Susceptible | The individual has not been exposed to the virus and has no immunity. Vaccination is often commend. |
⚠️ Note: If your event signal you are susceptible to the virus, confab your healthcare provider to discourse the Hepatitis A vaccinum, which is highly efficacious at ply long-term immunity.

High-risk groups, such as traveler to developing nation, soul with continuing liver disease, or those living in community with eminent rate of infection, are strongly promote to cognise their antibody position.
