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.

What does a negative HBsAg screen 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. In most cases this means that you will recover within 6 months.
When a patient is HBsAg negative and anti HBs positive What is the status of his or her hepatitis B infection?
HBsAg. If negative, acute HBV infection is ruled out (15). If positive, the patient is infected with HBV. A repeat test after six months will determine if the infection has resolved or is chronic.
What happens if you test negative for hepatitis B?
A negative test result indicates the virus may not be actively reproducing in the liver. In general, a person is considered very infectious when the test is positive, and less infectious when the test is negative. The loss of e-Antigen can occur naturally or as a result of drug treatment.
Is itching a symptom of hepatitis B?
Most people living with HBV have episodes with rashes that itch, or with an itch without the rash. Rashes can be caused by all kinds of things, but the skin truly does let us know when there is something going on with our body.
Can HBsAg become negative?
Patients who become HBsAg negative and develop antibody to HBsAg (anti-HBs) are diagnosed as having resolved hepatitis B [3,4]. This is an uncommon phenomenon in chronic HBV infection.
Can HBsAg positive become negative?
It can happen, especially in older adults after a long period of “inactive” hepatitis B infection. About 1 to 3 percent of people with chronic hepatitis B lose HBsAg each year, and about half of all people with chronic infections who live up to age 75 will lose HBsAg, depending on the amount of HBV DNA in their blood.
Can HBsAg turn negative?
What does a negative HBsAg test mean?
Higher levels of HBsAg are usually connected with a higher risk and lower levels of HBsAg are usually connected with a lower risk. However, negative results for serum HBsAg tests do not always represent a clearance or inactivating status of HBV viruses.
What is HBsAg (HBsAg)?
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. The body normally produces antibodies to HBsAg as part of the normal immune response to infection.

Does a negative HBV test mean that the virus is gone?
However, negative results for serum HBsAg tests do not always represent a clearance or inactivating status of HBV viruses. HCC could still develop in the absence of detectable HBsAg in serum.
