What is normal range of HBsAg?
For example, a hepatitis B surface antigen (HBsAg) level of less than 1 s/c is considered negative, while a level of more than 5 s/c is considered positive. Any value between 1 and 5 s/c is indeterminate and should be repeated.
What is HBsAb concentration?
The titer level of hepatitis B surface antibody (HBsAb) higher than 10 IU/L is considered to offer immunocompetent individuals adequate protection. However, whether this level is enough to the tumor patients during chemotherapy remains unclear.
How do you read Hepatitis A results?
Diagnosis of Hepatitis A Infection
- IgM negative / IgG negative: Most persons with these results have never contracted hepatitis A.
- IgM positive / IgG negative: This result indicates acute hepatitis A.
- IgM positive / IgG positive: This result indicates that acute hepatitis A occurred within the last six months.
What is the full form 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.
What does hepatitis B surface antibody non reactive 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.
What is the diagnostic interpretation of this patient’s hepatitis serologic test result (+) Hbsag (-) IgM anti-HAV (-) IgM anti HBc?
The presence of anti-HBc indicates previous or ongoing infection with hepatitis B virus in an undefined time frame. IgM antibody to hepatitis B core antigen (IgM anti-HBc): Positivity indicates recent infection with hepatitis B virus (<6 mos). Its presence indicates acute infection.
What is hepatitis A IgG positive?
IgG (immunoglobulin G) antibodies. They protect you against hepatitis A. If you test positive for them but not for IgM antibodies, it means you had a hepatitis A infection in the past or had vaccinations to protect against it.
