Hepatitis B Surface Antibody anti-HBs Blood Test

Also Known As

HBsAb

The Purpose of an Anti-HBs Test

Hepatitis B is one of several forms of viral hepatitis that infects the liver. This disease is highly contagious if you come into contact with the bodily fluids of someone who has hepatitis B. Some people only have a brief bout of illness, where they feel fatigued or nauseous, or they are jaundiced or lack an appetite. But others have a chronic form of hepatitis B, which elevates their risk of liver disease or cancer. It’s important to note that there is a hepatitis B vaccine that can prevent you from contracting the disease.

What Does the Anti-HBs Lab Test Measure?

The anti-HBs blood test detects the presence of antibodies produced by the immune system to fight a hepatitis B infection.

Who Should Take a Hepatitis B Surface Antibody Anti-HBs Test?

You should get tested if you suspect you’ve been in close contact with someone who has hepatitis B and have been exposed to their bodily fluids. You may also want an anti-HBs lab test if you have the following symptoms:

• Loss of appetite
• Jaundice
• Fever
• Fatigue
• Stomach pain and nausea

Anti-HBs Antibody Test Preparation

You don’t have to follow any special instructions prior to taking the anti-HBs test.

Anti-HBs Blood Test Results

In this case, a positive result is a good thing: It means you have antibodies, either from being vaccinated against hepatitis B or from previously having the disease and clearing it from your body. In those circumstances, you can’t get hepatitis B or pass it on to anyone else.
