What does it mean if anti-HBs is positive?
HBsAg (hepatitis B surface antigen): when this is “positive” or “reactive,” it means the person is currently infected with hepatitis B and is able to pass the infection on to others.
What is anti-HBs negative?
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 anti-HBs quantitative?
This automated assay on the Abbott Architect system provides a quantitative determination of Anti-HBs. The test is indicated for assessing the response to HBV vaccination, determination of HBV immune status and for the diagnosis of HBV infection when used in conjuction with clinical and other laboratory data.
When is anti-HBc positive?
Anti-HBc or HBcAb (hepatitis B core antibody) – this blood test remains positive indefinitely as a marker of past HBV infection. HBeAg (hepatitis B e-antigen) is generally detectable in patients with a new acute infection; the presence of HBeAg is associated with higher HBV DNA levels, thus, increased infectiousness.
How did my husband get hepatitis B?
Hepatitis B is an infection caused by a virus found in the blood. It can be spread during sex or through items that may have come in contact with infected blood, such as razors, toothbrushes, nail clippers, needles and syringes, and glucose meters.

- Vomiting.
- Abdominal pain.
- Dark urine.
- Clay-colored bowel movements.
What happens if my hep B titer is negative?
A Word From Verywell. If all of your hepatitis tests are negative, it indicates that you have not been exposed to the virus and are not immune. If this is the case, talk to your healthcare provider about getting vaccinated whether or not you are at risk of hepatitis B.
