What does a high hepatitis B surface antigen mean?
Hepatitis B surface antigen (HBsAg): A protein on the surface of hepatitis B virus; it can be detected in high levels in serum during acute or chronic hepatitis B virus infection. The presence of HBsAg indicates that the person is infectious.
What is a hepatitis B surface antibody titer?
The hepatitis B surface antibody test (HBsAb), looks for antibodies that your immune system makes in response to the surface protein of the hepatitis B virus. The hepatitis B surface antibody is also referred to as anti-HBs and should not be confused with HBsAg, which stands for hepatitis B surface antigen.
How do you get hepatitis B surface antigen?
HBV is spread through blood, seminal fluid, and vaginal secretions. It can take several months to develop symptoms of hepatitis B after you become infected. The virus causes an infection in the liver.
What is Hep B surface AB non reactive?
Normal results are negative or nonreactive, meaning that no hepatitis B surface antigen was found. If your test is positive or reactive, it may mean you are actively infected with HBV. In most cases this means that you will recover within 6 months.
Can CBC detect hepatitis B?
Diagnostic Tests It is also common for a patient with hepatitis B to have a low white blood cell count, so your doctor may also request a complete blood count. If the blood tests show the presence of hepatitis B surface antigen (HBsAg) for longer than six months, that is a sign of chronic hepatitis B.
What does non reactive Hep B surface mean?
Normal results are negative or nonreactive, meaning that no hepatitis B surface antigen was found. If your test is positive or reactive, it may mean you are actively infected with HBV.
What is the normal range for hepatitis B surface antibody?
Reference Range. Any value between 1 and 5 s/c is indeterminate and should be repeated. For hepatitis B surface antibody (anti-HBs), a level less than 5 mIU is considered negative, while a level more than 12 mIU is considered protective. Any value between 5 and 12 mIU is indeterminate and should be repeated.
Can I infect with hepatitis B?
Hepatitis B is really contagious. It’s transmitted through contact with semen (cum), vaginal fluids, and blood. You can get it from: having vaginal, anal, or oral sex (using a condom or dental dam during sex can help prevent it) getting stuck with a needle that has the Hep B virus on it.
How easily is hepatitis B (HBV) transmitted?
Hepatitis B (HBV) can spread up to 100 times more easily through sexual contact than HIV, the virus that causes AIDS. HBV can be in vaginal fluids, saliva, and semen. It can be transmitted by oral sex and especially anal sex. It is not transmitted by holding hands, hugging, or even dry kissing on the lips.
What test checks for hepatitis B immunity?
He is Verywell’s Senior Medical Advisor. The HBsAb test, or hepatitis B surface antibody test, looks for antibodies that your immune system makes in response to the surface protein of the hepatitis B virus.
