What is the normal result of anti-HBs?
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 does high anti-HBs mean?
A positive anti-HBs (or HBsAb) test result means you are “immune” and protected against the hepatitis B virus and cannot be infected. You are not infected and cannot spread hepatitis B to others.
What does positive hepatitis B IgG mean?
A positive/reactive anti-HBc IgG test usually indicates a chronic infection. Other Tests: Liver Enzymes (ALT / SGPT), AST / SGOT) – These blood tests measure potential liver damage (or liver inflammation)caused by the hepatitis B virus.
What does a negative anti-HBs 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 HBs antibody?
The hepatitis B surface antibody (HBsAb) test detects and measures antibodies produced by the immune system in response to the hepatitis B virus. It is one of several tests used to diagnose hepatitis and is used specifically to determine your level of immunity to the virus.
What is anti HBs qualitative test?
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 does anti-HBs appear?
A positive anti-HBs result is consistent with a previous HBV infection. A result ≥ 10 International Unit/Liter (≥ 10 IU/l) also appears between 1 and 6 months following a successful vaccination against hepatitis B.
What is anti-HAV IgG reactive?
The presence of anti-HAV (IgG or IgM) in human serum or plasma is indicative of past or present infection with hepatitis A virus (HAV) or vaccination against HAV. The test for total anti-HAV is primarily used to determine exposure to HAV either naturally or due to vaccination.
Is anti-HBs IgM or IgG?
Anti-HBc IgG and IgM appear shortly after the symptoms and onset of the virus surface antigen (HBsAg). IgM arrives first and is then replaced by IgG. Anti-HBc IgG are interpreted in light of clinic factors and the results of other hepatitis B markers, particularly HBsAg and anti-HBs.
Is anti-HBs an IgG?
IgG1 is the predominant anti-HBs antibody after HBV infection, in either chronic carriers or in HBV-cured individuals. This finding is partly inconsistent with data reported from other group who suggested in individuals naturally infected, the anti-HBs IgG consists mainly of IgG3 and IgG1.
What is the normal range of hepatitis B viral load?
HBV: Hepatitis B virus. # Normal values: ALT: Males: 10-40 U/L; Females: 7 – 35 U/L; AST: Males: 15 – 40 U/L; Females: 13 – 35 U/L. HBeAg-positive patients had significantly higher ALT levels (mean 170.3 ± 391 IU/L) compared to HBeAg-negative patients (mean 53.9 ± 169.4 IU/L), p < 0.0001 (Table 2).
What is normal range of hepatitis B?
The ranges for hepatitis B surface antibodies are: Anti-HBs greater than 10-12 mIU/mL: Protected against hepatitis B virus (HBV) infection, either from vaccination or successful recovery from a previous HBV infection.
What does a positive anti-HBc IgG mean?
A positive anti-HBc IgG result may indicate that the individual has eliminated the virus and is now immune (negative HBsAg/positive anti-HBs) or is in a recovery phase (negative HBsAg and anti-HBs / negative or positive IgM, anti-HBc). When combined with a positive HBsAg, an active chronic infection may be suspected.
What do anti HBs mean?
antibody (anti-HBs): 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. Total hepatitis B core
What does a negative HBc IgG and HBsAg result indicate?
The combination of negative anti-HBc IgG and HBsAg results, but positive anti-HBs results indicates an individual that has been vaccinated against hepatitis B.
What is HBsAg antigen?
HBsAg is the antigen used to make hepatitis B vaccine. Hepatitis B surface antibody (anti-HBs): 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.
