Hepatitis B: Should I Be Tested?

Get the facts

Your options

  • Have a blood test for hepatitis B.
  • Do not have the test.

Key points to remember

  • Hepatitis B often causes no symptoms, so many people don't know that they have it until they get tested.
  • People with hepatitis B may not need treatment if the disease hasn't caused any liver problems. But it can cause serious liver problems, such as cirrhosis, liver cancer, or liver failure. Treatment may prevent liver problems in some people.
  • You can get shots to keep from getting hepatitis A or B.
  • If you know that you have hepatitis B, you can take steps to keep from spreading it to others.
  • Having to tell friends and family that you have hepatitis B could affect your relationships.
FAQs

What is hepatitis B?

Hepatitis B causes inflammation of the liver. It is spread through infected blood and body fluids. Hepatitis B is spread most often during sexual contact and when people share needles to inject drugs.

Hepatitis B can also be spread when an infected person shares items such as razors or toothbrushes.

Sometimes a baby is infected at birth because the mother has hepatitis B.

Many people have hepatitis B for years without knowing it, because they have no symptoms.

Hepatitis B can cause serious liver problems, such as cirrhosis, liver cancer, or liver failure. But some people never have serious problems.

Most adults who get hepatitis B have it for a short time and then get better on their own.

What is the test for hepatitis B?

You can have a blood test to find out if you have hepatitis B. A small amount of blood is drawn from your arm. The blood is sent to a lab.

The test looks for hepatitis B antibodies. Having these antibodies means that you have been exposed to hepatitis B, but it does not mean that you now have an active infection.

If the test shows that you have been exposed to hepatitis B, your blood may be tested again to see if the virus is still in your blood. The second test shows whether you have an active hepatitis B infection. For the second test, the lab may use some of the blood that was already drawn, or you may need to have more blood drawn.

What are the benefits of getting tested?

  • Getting tested can lead to early treatment, which may help prevent a long-term infection.
  • If you know that you have hepatitis B, you may decide to tell people who may have given you the disease, so that they can get tested. People you may have infected also could be tested.
  • If you know that you have the infection, you can take steps to avoid spreading it.
  • If your test shows that you don't have hepatitis B, you can get a vaccine to keep you from ever getting it.

What are the risks of getting tested?

If you find out that you have hepatitis B, you have to decide whether to get treatment.

  • A new hepatitis B infection in adults usually does not need to be treated. It usually goes away on its own. But in some people it leads to long-term (chronic) infection and serious liver problems.
  • Some of the medicines used to treat hepatitis B have few or no side effects. But others can cause serious side effects, such as constant tiredness, headaches, a fever, nausea, thyroid problems, or depression.

Why might your doctor recommend that you get tested?

Your doctor might advise you to get tested for hepatitis B if:

  • Your job or your lifestyle puts you at risk for getting hepatitis. For example:
    • You have sex without using a condom with more than one partner.
    • You share needles to inject drugs.

Personal stories about hepatitis B testing

These stories are based on information gathered from health professionals and consumers. They may be helpful as you make important health decisions.

I have been sexually active for years and have had at least a dozen sex partners. I'm going to have a hepatitis B test. I have a friend who went through treatment a year or so ago. He was pretty miserable, but he came out all right. If he can do it, I can. I think I owe it to myself to find out if I have hepatitis B.

Jax, age 40

I had several sex partners when I was in my 20s, but I don't consider myself promiscuous. I sometimes worry that I could have hepatitis B, but I think the odds are in my favor that I don't have it, so I'm not going to be tested.

Karen, age 33

I did drugs in my teens and shared needles a couple of times. I just recently read an article about hepatitis B, and I think I'll get tested. I don't want to deal with the treatment decision right now, but I want to know if I have it.

Malik, age 29

I lived with a woman who had hepatitis B, and I watched her go through the treatment. She had a rough time of it for a year. I don't think I could handle feeling that sick for so long. So I'm not going to be tested, because I don't think I would go through the treatment even if it turned out I have hepatitis B.

Sam, age 44
