H Bs Ag Test
Hepatitis B: If you have hepatitis b surface antigen in your circulation you have been infected with the virus. The duration or persistence of the surface antigen will determine whether this was acute or chronic infection. See a doctor to determine future testing and assessment techniques and possible need for treatment. There are now effective meds available. ...Read more
What is a normal value for the HBsAG test? Hbsag was negative, Value was less than 0.5, the report shows negative
Why my HBsAG test has a number value of 0.19? I know is negative but what does the number mean? Are those dead virus? Or ramping up to be positive?
With EIA testing...: EIA = enzyme immunoassay. With EIA, the number isn't a quanity but a ratio, the strength of reaction in the patient's specimen compared with a control reagent. It has to do with the chemistry of the test, not the amount of HBsAg in blood. The identical specimen tested 10 times can give 10 different numbers. Any result below the cut-off is totally negative, indicating zero HBsAg in the blood. ...Read more
Lft normal, HBV DNA 13 iu/ml and HBsAG (eliza test) austrailian antigen comes 1.36 (decreasing per yr) in how long can I be relieved of hepatitis b?
Depends: You are young and without knowing more information, hard to say. However, some can clear hepatitis b on their own, while most people have a lifelong chronic hepatitis b state that can be "active" or "inactive". That is why it is very important that you see a hepatitis b liver specialist to determine your course and if you need to be treated with antivirals or have lab tests occasionally! ...Read more
HBsAg serum test shows reactive (CMIA 1.35). What does this mean? Also I'm 37 weeks pregnant, will it affect my baby?
My hepb serology hbasg +ve, confirmatory test hbsag-ve, hbcab, hbsab, hbeag, hbeab are all -ve, this is 3rd tym same result, am I infected?
My vote is...: No, based on the confirmatory results that antigens and antibodies are negative. As the surface antibody (HBsAb) is currently negative, one can ask his primary care for Hepatitis B vaccines, to acquire protection. However, if one was exposed recently, and got a new infection, he could be in the brief window period, if the HBcAb test was for IgG only (thus missing HBcAb IgM). His Dr. Can explain. ...Read more

Baby born to mom HBV carrier. Soon he received hbig & 1st HBV vaccine and after 2&3 add when boy's 1-6 month and got test. Hbsag - but antihbs 8 miuml?
Male age 40 with hep b HBsAG +ve. Blood test show cholesterol 204, neutrophils 41.4% (2400), lymphocytes 49.1% (2840). Acute or chronic? Need treatment?
Hepatitis B Therapy:
In general, hepatitis b in a chronic form needs a full evaluation including hbsag, hbsab, hbeag/ab, viral dna, AFP and sonogram. Depending on these results, therapy may be indicated. Please review attached video for further info:

Elisa hbsag was negative in may 2013 befr my dnc. Now another lab test shows hbsag positive during blood test fr fertility treatmnt. Can tis be true?
Yes, but...: If a person converts from HepBsAg negative to HepBsAg positive, her primary care doctor can evaluate her and order a larger panel of Hepatitis B tests to see what is going on. If HepBsAg is confirmed to be positive, the patient is contagious with HepB viruses (which are spread through blood and bodily fluids contact). That means all household contacts should have their HepB immunity confirmed. ...Read more
Negative for HbSag: Initial screening tests are set at high sensitivity and generate some false positives. If the confiramtory test was negative and you do not have any other indication of hep b infection, then the results of the confimatory tests are the definitive results. ...Read more
Check for immunity: Hbsag (surface antigen) tests for active hepatitis. If it's negative, you don't have it and don't need retesting unless you get exposed. However, you should get a hbsab (surface antibody) to see if you're immune. If the antibody is negative, you should be vaccinated, and then you'll never need to worry about getting hepatitis b. ...Read more
Should I be concerned if my partner got a result of HBsAG non reactive for hepa test. Is she already infected?
Hepatitis B: I may be misreading your question, but I need clarification. Why is your partner testing? Do you have hepatitis b? Have you not been vaccinated for this common and dangerous virus? Most americans are vaccinated now against hepatitis b. The test results you share show that she is not positive or immune to hepatitis b. ...Read more
Hbsag possitive suspected in my blood due to elissa test count is 3.9. have any problems for my future life, should I be concerned?
If you are hepatitis b reactive, and then you are test again for HBsAG and the result is non reactive what does it mean? You don't have hbv?
Reactive to what?: Hbv markers are used to distinguish actively infected from immunity, the latter include antibody to surface antigen (hbsab) and to the core antigen (hbcab). Some tests detect part of the virus, such as surface antigen (hbsag), the core antigen, or hbv dna. The presence of hbsag indicates that the person is potentially infectious. Hbsab replaces hbsag as the hbv infection evolves to immunity. ...Read more
Age m 31 bp140/90 under medic amlodopine 5mg and telmasrine 20mg. Have hbsag+ ve non reactive. How save my liver. 2 year before liver funct test ok?
Amlodipine/Hepatitis: With the limited information you've given, hbsag negative means you do not have liver disease caused by hepatitis b. Amlodipine has small chance of causing hepatitis. If you are taking this medication, not routinely need to check liver function test. Should have annual blood work up as you routinely would. ...Read more
I wonder what my test results means, here they are HBsAG screening positive, hbeag negative, anti hbs negative pls. Help me?
Acute hepatitis B: These test results are as follows: hepb surface antigen - a protein seen on the surface of hepatitis virus-if it is positive, but the anti- hepatitis b surface antibody is negative, then the infection is relatively recent because there has not been enough time to develop antibodies. In this stage it is possible to spread the virus to others. However, e antigen is low, so less infectious. ...Read more

I have donated blood and it was screened to have a positive in hbsag. Then I went to have my blood test and the results were 3986.57 what should I do?
Which additional tests do I require to be diagnosed with hep b? Last year I got HBsAG positive, DNA HBV negative results. Which other markers of HBV tests should I be tested for to know whether I am a carrier and can infect others?
There are a number of hepatitis b virus (hbv) markers that are used to determine whether one is actively infected, latently infected, immune, or vaccinated. Some are tests to detect antibody, for example, antibody to hbv surface antigen (sometime referred to as hbsab), antibody to the hbv core antigen (referred to as hbcab) [and a subset of the core antigen is the "e" antigen, so antibody to that is referred to as the hbeab]. Some tests detect part of the hbv itself, so the surface antigen is referred to as hbsag, the core antigen - hbcag, the e antigen - hbeag, or the dna itself or hbv dna.
Hbsag can be detected in the blood from several weeks before onset of symptoms to months after onset. Hbsag is present in serum during acute infections and persists in chronic infections. The presence of hbsag indicates that the person is potentially infectious, regardless of the hbv dna level.
Hepatitis b virus, hbv dna, hbcag and hbeag are also evidence of ongoing infection. The presence of hbeag is associated with relatively high infectivity and severity of disease.
Anti-hbc is the first antibody to appear. Demonstration of anti-hbc in serum indicates hbv infection, current or past. Igm anti-hbc is present in high titre during acute infection and usually disappears within 6 months. Igg anti-hbc generally remains detectable for a lifetime.
Anti-hbe appears after anti-hbc and its presence correlates to a decreased infectivity. Anti-hbe replaces hbeag in the resolution of the disease. Nowadays, hbv dna has often been used to replace testing for hbeag.
Anti-hbs replaces hbsag as the acute hbv infection is resolving. Anti-hbs generally persists for a lifetime in over 80% of patients and indicates immunity. It is the only antibody which appears in normal patients who are vaccinated with the hbv vaccine. The presence of other antibodies suggest that the immunity was acquired thru a prior active infection rather than vaccination. ...Read more

Hepatitis b blood test shows both anti-hbs (i was vaccinated 13 years ago) and hbsag. Does that mean I was recently exposed or that I am chronic?
The latter: It is likely, if the test results are confirmed, that you were a chronic carrier of HBV before you were vaccinated. Some people have both HBsAG and antihbs and behave as other chronic carriers. ...Read more
