What does reactive results mean in hep b?

Reactive results in a hepatitis B (HBV) test mean that the person has antibodies to the hepatitis B virus. This means that the person has been exposed to the virus and their immune system has responded by producing antibodies.

There are two types of antibodies that are tested for in a hepatitis B test:

* HBsAg (hepatitis B surface antigen): This antibody is present in people who are currently infected with HBV.

* HBcAb (hepatitis B core antibody): This antibody is present in people who have been infected with HBV in the past, regardless of whether or not they are still infected.

A reactive result for HBsAg means that the person is currently infected with HBV. A reactive result for HBcAb means that the person has been infected with HBV in the past, but it is not clear whether or not they are still infected.

If a person has a reactive result for HBsAg, they should be tested for HBV DNA to confirm the diagnosis of HBV infection. If a person has a reactive result for HBcAb, they should be tested for HBsAg to determine if they are still infected with HBV.

What does it mean to be reactive to hepatitis B?

Being reactive to hepatitis B means that you have antibodies to the hepatitis B virus (HBV) in your blood. This means that you have been exposed to the virus and your body has produced antibodies to fight it off.

There are two types of antibodies that can be tested for in a hepatitis B test:

* HBsAg: This antibody is present in people who are currently infected with HBV.

* HBcAb: This antibody is present in people who have been infected with HBV in the past, regardless of whether or not they are still infected.

If you test reactive for HBsAg, it means that you are currently infected with HBV. This is a serious condition that can lead to liver damage and liver failure. If you test reactive for HBcAb, it means that you have been infected with HBV in the past, but it is not clear whether or not you are still infected. You may need to have further testing to determine if you are still infected.

What should I do if I test reactive to hepatitis B?

If you test reactive to hepatitis B, you should see a doctor right away. Your doctor will recommend the best course of treatment for you. Treatment for hepatitis B may include:

* Antiviral medications: These medications can help to slow down the progression of the disease and prevent serious liver damage.

* Liver transplant: In some cases, a liver transplant may be necessary.

It is important to follow your doctor's instructions carefully if you are diagnosed with hepatitis B. Early diagnosis and treatment can help to prevent serious complications.
