HBV test results: Hepatitis B Surface Antigen: Nonreactive; Hepatitis B Core Antibodies: Reactive; HBV PCR: Negative. Need any medication or vaccine?

HBV test results: Hepatitis B Surface Antigen: Nonreactive; Hepatitis B Core Antibodies: Reactive; HBV PCR: Negative.  Need any medication or vaccine?

Excellent question: and your story stumps many a doctor, often! :) a lot of the recommendations depend on - are you someone with risk factors for HBV? is this the first time that it has been checked? are your liver enzymes normal? are you about to undergo any procedures/ treatments that could put you at risk for HBV? If you have no sig risk factors, yes, I'd vaccinate you if there's potential for exposure. ...Read more

IMy HBV test results (red cross): Hepatitis B Surface Antigen: Nonreactive; Hepatitis B Core Antibodies: Reactive; HBV PCR: Negative.  Do I have HBV?

Cured, but...: If a person's Hep B surface antigen is nonreactive, that means the lab does not find pieces of the surface of the virus. If her Hep B virus PCR is negative, that means the lab does not find the virus's DNA (genes). If the core antibody is reactive that means her immune system REMEMBERS being infected with Hep B. She is cured, but some viral DNA might be attached to her own human DNA in her liver. ...Read more

Test result was "Hepatitis Surface Antibody - Nonreactive" and "Hepatitis B Surface Antigen  - Reactive", "HBS AG Confirmation - Nonconfirm".

Hmmmm: Got me beat. A reactive Hep B antigen indicates that you have Hepatitis B. However, It looks like the test was NOT confirmed. My experience with labs is that their report format could use some improvement and you may be misreading this. Talk to the doc who ordered the test. ...Read more

Hi please help, hepb surface antigen positive, hep b surface antigen confirmatory negative, antibody negative and anti core negative.What does it mean?

Hepatitis B testing: You should have it rechecked. Hbsag or surface antigen tests are the same, not like in HIV which has screening and confirmatory test. Normally, in the window period after an acute infection, all test for surface antigen or its antibodies are negative except for antibody to core antigen. Hbsag or surface antigen appears right after infection or exposure and disappears in recovery. ...Read more

Elevated EBV ab VCA IgG <8 and EBV nucleaer antigen ab IgG test 4.2. & anti-dna(ss)igg ab qn ( 119)& c react protien(5.6) what are implications?

Elevated EBV ab VCA IgG <8 and EBV nucleaer antigen  ab IgG test 4.2. & anti-dna(ss)igg ab qn ( 119)& c react protien(5.6)  what are implications?

Nothing.: Ebv antibodies indicate you had a previous infection, but not active. The c-reactive protein needs a units indicator - that is either normal or somewhat elevated. The anti ss dna is extremely nonspecific and very rarely indicated; I have no idea why that was ordered, discuss with your doctor. ...Read more

Well : A positive hepatitis C antibody test with a negative or in a test usually is not a false positive that usually means someone had hepatitis C infection and their body cleared the infection and they are now immune to hepatitis C.

Hepatitis b surface antigen non-reactive means what?

No active infection: When people have reactive hepatitis b surface antigen, they have proteins from hepatitis b in their blood. These people have active infection and may need treatment. If there is no reactive hbsag, then most likely there is no active infection. Rarely, people who have hepatitis b core antibody detected, but no hepatitis b surface antibody, can have chronic active infection. ...Read more

What is hepatitis b surface antigen in general?

What is hepatitis b surface antigen in general?

Infection is active: If you are surface antigen postive = protein on the surface of the virus is in its active form which is still floating in your blood and indicates active/on going infectious state. This protein triggers body to produce antibody which can help rid off the infection or preventing it as in case of hepb vaccines. In your case, no antibody or not enough to rid of the antigen. Consult doc. Good luck. ...Read more

Help please? What is the hepatitis b surface antigen?

Hepatitis B: If you have a positive hepatitis B surface antigen, then you have active hepatitis B infection. You can see a hepatologist (liver doctor) to check some other labs in order to determine if you need to be on treatment with oral medications or if a liver biopsy should be considered based on other laboratory results. Having hepatitis B can be controlled with medications. ...Read more

Wondering if hepatitis b e antigen reactive can be cured?

Wondering if hepatitis b e antigen reactive can be cured?

Yes and no: It's possible to convert from e antigen (hbeag) to e antibody (hbeab) with treatment of hepatitis b. This is a good thing, as it means your hepatitis is less active and you are less infectious to others. However, hepatitis b itself is not considered to be 'curable, ' and conversions from surface antigen (hbsag) to surface antibody (hbsab) rarely happen. ...Read more

If my husband has hepatitis b core antigen & i drink from koolaid jug after him, could i catch it?

Forgive my frankness: Hopefully you've been immunized against hepatitis b, and were immunized before you got married. That'll protect you. Even more, i would hope that you and your husband are doing all kinds of wonderful things together that involve far more intimate exchanges than drinking kool aid. If not, why not? It's well worth the risk. Best wishes to you both. ...Read more

"having core antigen" isn't a standard lab -- have you been told she's infectious? Even if she is, hopefully as her husband you have been and are more intimate with her than sharing glassware. Have your physician explain this. ...Read more

Does a hEPATITIS B SURFACE                        ANTIGEN W/REFL CONFIRM mean you have the virus?

It sounds like it: I'm not entirely certain about the terminology you report but I would interpret what you have given as confirming that the specimen is positive for hepatitis B surface antigen (a confirmation of which was done "reflexly" when initial test looked positive). This indicates the presence of the active hepatitis B virus and suggests the presence of infectivity. Discuss next steps with your doctor! ...Read more

My hepatitis b surface antigen test was nonreactive and my hepatitis b surface antibody test was equivocal do I have hepatitis b or not? I'm worried

No worries unless...: No worries, until one's primary care doctor looks at the patient's details. If a person has negative HepB surface Antigen, and is at low risk for having HepB, then he does not have HepB. However, if he is medium or high risk for HepB, then his Dr. would likely have also checked HepB core Antibody. If core Antibody also negative, he should not have HepB. Details matter. If worried, ask primary Dr. ...Read more
