What does a positive hepatitis B surface antibody QL mean?

What does a positive hepatitis B surface antibody QL mean?

A positive HBsAg test result means that you are infected and can spread the hepatitis B virus to others through your blood. anti-HBs or HBsAb (Hepatitis B surface antibody) – A “positive” or “reactive” anti-HBs (or HBsAb) test result indicates that a person is protected against the hepatitis B virus.

Does hepatitis B surface antibody mean immunity?

Having immunity against hepatitis B results in a positive hepatitis B surface antibody test. 6 It means you’ve either recovered from the infection or have been successfully vaccinated.

Why did I test positive for hepatitis B?

If the blood bank told you your test was “positive,” it is important to find out which test was positive. If the “HBsAg” was positive, this means that you are either chronically infected with hepatitis B or were recently infected.

Will you test positive for Hep B if you have been vaccinated?

Your body can make this antibody if you have been vaccinated, or if you have recovered from a hepatitis B infection. If this test is positive or “reactive,” then your immune system has successfully developed a protective antibody against the hepatitis B virus.

Can you lose immunity to Hep B?

All subjects responded with anti-HBs (mean titer, 143 mIU/mL). The duration of immunity after vaccination against HBV is not known. Ten percent of the patients who receive and respond to vaccination lose anti-HBs after 5 years and 50% lose anti-HBs after 10 years.

What does low immunity to hepatitis B mean?

Answer. This means that you are susceptible (can catch) hepatitis B. Often these words are used when the blood tests for hepatitis B do not show reactive, or levels of, hepatitis B surface antibody (sAb).

Can your body cure hepatitis B?

Most adults with hepatitis B recover fully, even if their signs and symptoms are severe. Infants and children are more likely to develop a chronic (long-lasting) hepatitis B infection. A vaccine can prevent hepatitis B, but there’s no cure if you have the condition.

When do you test for Hep B antibodies after vaccination?

Postvaccination testing should be done 1–2 months after the last dose of hepatitis B vaccine. If adequate anti-HBs is present (>10mIU/mL), nothing more needs to be done.

How do I know if I am immune to hepatitis B?

A hepatitis B surface antibody test is used to check for immunity to HBV. A positive test means you are immune to hepatitis B. There are two possible reasons for a positive test. You may have been vaccinated, or you may have recovered from an acute HBV infection and are no longer contagious.

What is borderline Hep B surface antibody?

Borderline results may indicate a low level of antibody that has clinical significance. Patient’s immune status should be further assessed by considering other clinical information or retesting another specimen drawn at a later time.

Can you lose immunity to hepatitis B?

The duration of immunity after vaccination against HBV is not known. Ten percent of the patients who receive and respond to vaccination lose anti-HBs after 5 years and 50% lose anti-HBs after 10 years.

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.

What is hepatitis B virus surface AB?

Hepatitis B virus (HBV) is a DNA virus in the Hepadnaviridae family. It has a lipoprotein-coated surface, which is called the surface antigen (HBsAg, previously called Australia antigen).

What does it mean if Hep B surface antibody is non reactive?

Hep B antigen “non-reactive”. My understanding is that surface antigen positive means you are infected regardless of any antibody status. If you clear the antigen and develop antibodies, then you are immune. So, get a hard copy of your lab results and then post them here. As a carrier you are “contagious” but…

What does hepatitis B surface antibody mean?

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. 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 .
