hepatitis B surface antigen (HBsAg)
Anti-HBs or HBsAb (hepatitis B surface antibody)
Anti-HBc or HBcAb (hepatitis B core antibody)
Hepatitis B E antigen
Anti-HBe or HBeAb (hepatitis b e antibody)
But in the process of roughly judging infectious diseases, only referring to the first three indicators, we can roughly analyze the situation of hepatitis B infection. These three indicators refer to:
hepatitis B surface antigen (HBsAg)
Anti-HBs or HBsAb (hepatitis B surface antibody)
Anti-HBc or HBcAb (hepatitis B core antibody)
Let me give you a detailed introduction to the specific meaning of these three indicators.
HBsAg (hepatitis B surface antigen) represents a special substance on the surface of hepatitis B virus. The test results show that "positive" or "reactive" means that the patient is infected with hepatitis B. If someone is positive, further tests are needed to determine whether this is a new "acute" infection or a "chronic" hepatitis B infection. Simply put, a positive HBsAg test means that you have been infected and can spread hepatitis B virus to others through blood.
Composition of hepatitis B virus
Anti -HBs or HBsAb (hepatitis B surface antibody) Anti -HBs or HBsAb test results show that the person's body has been protected by hepatitis B virus and will not be infected again. This protection comes from two aspects:
1, probably vaccinated with hepatitis B vaccine.
2. It may also be the result of the recovery of antibodies obtained after the body is infected with hepatitis B virus.
In other words, anti -HBs (or HBsAb) test is positive, indicating that the body has been "immune" to hepatitis B virus infection, and the virus can not infect the body, nor can it spread hepatitis B to others.
Anti-HBc or HBcAb (hepatitis B core antibody) The results of anti-HBc or HBcAb test show that "positive" or "reactive" indicates that you have been infected with hepatitis B virus in the past or now. This blood test can remain positive indefinitely as a sign of past HBV infection. This core antibody does not provide protection for the body like the hepatitis B virus surface antibody above. Therefore, only on the premise of HBsAg and anti -HBs can we fully understand the results.
Therefore, according to your medical report:
HBsAg (hepatitis B surface antigen) = = = = >; Negative; Negative; Negative; negative
Anti-HBs or HBsAb (hepatitis B surface antibody) = = >; active
Anti-HBc or HBcAb (hepatitis B core antibody) = = >; Positive (low)
The results show that your hepatitis B infection has recovered naturally at this time, and it is not contagious at this time, which is a characteristic manifestation of the improvement of your condition.
I hope it will help everyone.
