What does HBsAg negative mean?
If the HBsAg is negative it means you are protected and immune from infection. This protection can be the result of receiving the hepatitis B vaccine or of a successful recovery from a past hepatitis B infection. This test is not routinely included in blood bank screenings.
What does anti HBc negative mean?
A negative total anti-HBc result may indicate the absence of a recent or previous HBV infection (negative HBsAg and anti-HBs). However, a developing infection cannot be ruled out.
What is HBs antigen test?
HBsAg (Hepatitis B surface antigen) – A “positive” or “reactive” HBsAg test result means that the person is infected with hepatitis B. This test can detect the actual presence of the hepatitis B virus (called the “surface antigen”) in your blood.
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. During stage HBV DNA may still be detectable by PCR in serum and more often in the liver.
What is HBsAg test?
The “Hepatitis B Panel” of Blood Tests HBsAg (Hepatitis B surface antigen) – A “positive” or “reactive” HBsAg test result means that the person is infected with hepatitis B. This test can detect the actual presence of the hepatitis B virus (called the “surface antigen”) in your blood.
What does anti-HBs indicate?
The presence of anti-HBs is generally interpreted as indicating recovery and immunity from hepatitis B virus infection. Anti-HBs also develops in a person who has been successfully vaccinated against hepatitis B.
What is hepatitis B AG?
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 meaning of HBsAg?
Following infection with hepatitis B virus (HBV), hepatitis B surface antigen (HBsAg) is detectable in the serum before liver function tests become abnormal and before development of clinical features of hepatitis; HBsAg tests usually become negative shortly after illness subsides.
Can you test negative for hepatitis B and still have it?
Most adults who acquire HBV clear the virus within a few months, and their hepatitis B surface antigen test result will be negative after that time. Some people remain infected and continue to test positive for hepatitis B surface antigen.
Can hepatitis B go away?
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.
