What does a non reactive hep b surface antibody mean?
HBsAg non-reactive does NOT mean immune to hepatitis B. To understand this we have to discuss what exactly HBsAg is. The hepatitis B virus has several components. It is an encapsulated virus, meaning that its central DNA core is protected by an outer shell. This shell is sometimes called the "surface". On this surface are some antigens, which are simply proteins that induce an immune response in the body. We abbreviate these antigens as HBsAg, which is shorthand for "hepatitis B surface antigen". If a blood test reveals that there are no detectable hepatitis B surface antigens, this simply means that the individual has no evidence of being currently infected with hepatitis B. Otherwise, there would be some hepatitis B surface antigens (with hepatitis B DNA inside them) floating around in the bloodstream. To determine if a person is immune to hepatitis B, we must draw a different test. This test checks for the presence of antibodies to the hepatitis B surface antigens. Sometimes this is abbreviated as HBAb, or as Hepatitis B IgG. If the patient has antibodies to Hepatitis B surface antigens, and has no detectable HBsAg in their bloodstream, then it is likely that they are immune. But be careful! Simply having Hepatitis B surface antibodies does not indicate immunity! It may mean that the person is actually infected with Hep B. This is why both tests are necessary to document immunity.
Who identified the Hepatitis b virus and developed the diagnostic test and vaccine for it?
Identification by symptoms,enlargement of liver,yellow eyes, vomiting ,dyspepsia, etc diagnostic test ,(hb antigen serfice test) HBsAg test,securing test. vaccination ,we have vaccine for hepatitis b,it safe us against hepatitis b.
What is Australian antigen test?
Australia antigen,1 an envelope antigen known as hepatitis B surface antigen (HBsAg), found in acute or chronic hepatitis B.2 a serologic marker on the surface of the hepatitis B virus.It is commonly referred to as the Australia Antigen. This is because it was first isolated by the American research physician and Nobel Prize winner Baruch S. Blumberg in the serum of an Australian Aboriginal person.It was discovered to be part of the virus that caused serum hepatitis by virologist Alfred Prince in 1968.Heptavax, a "first-generation" hepatitis B vaccine in the 1980s, was made from HBsAg extracted from the blood plasma of hepatitis patients. Current vaccines are made from recombinantHBsAg grown in yeast.
What is HBSAG Elisa test normal range?
The normal range for HBsAg (Hepatitis B surface antigen) in an ELISA test is typically less than 0.05 IU/mL. Values above this range may indicate a presence of Hepatitis B infection. It is important to consult with a healthcare provider for interpretation of test results.
Can hepatitis B be spread by sex and can a baby be infected?
Hepatitis B can be spread by sexual means.
How HBsAg will be negative?
It will be negative if there has never been any exposure to hepatitis B virus. ALSO , in the inactive carrier state (3-6 months) it is negative. In most cases in a matter of months HBsAg disappears and failure to clear it within 6 months is a sign of chronic infection.
What is the difference between chronic hepatitis b and carrier of hepatitis B?
Chronic hepatitis B is a liver disease caused by a virus. Being a carrier of hepatitis B means that you are infected with the virus and can transmit it to others, but you may not have the disease
What pathogens cause hepatitis b?
The causative agent for Hepatitis B is Hepatitis B virus.
What means Anti-HBs non reactive?
Anti Hbs is a titer measuring antibodies to the hepatitis B surface antigen. Anti Hbs reactive means that you are immune to hepatitis B, either due to previous immunization or recovery from hepatitis B.
What does no evidence of immunity mean in a blood test for hepatitis b?
It means that the patient has not been exposed to hepatitis B (ie is not and has not ever been infected with it) and that the patient has not received a vaccine against hepatitis b.
If someone had the HBs Ag Quantitative test and the result was Reactive 250 IUml what does that means?
This stands for Hepatitis B Surface Antigen. It means that you have Hepatitis. If the HBsAB was positive, it would have meant that you have had hepatitis B in the past and have built antibodies.
Can you give hepatitis b vaccine to someone with hepatitis B?
There is no harm or benefit from giving hepatitis B vaccine to someone with hepatitis B.
