Window for hcv ab test and hcv rna test?

Window for hcv ab test and hcv rna test?

HCV: Nowadays with polymerase chain reaction technology it is making "window" periods a less discussed issue. In my practice if I suspected a recent infection (say days to weeks old)..this test would show virons in your blood. Once this virus hits your bloodstream it explodes exponentially. Some people are fortunate that their bodies contain the infection..most do not. ...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?

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

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

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

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

What can cause false positive ELISA HIV test? 2 confirmatories neg and viral load neg. No bands detected.

Many things: An elisa test for HIV is very sensitive which basically means it is a good test for ruling out HIV and is only reliable when negative. A positive elisa test does not mean someone has HIV and is frequently called a "false positive" there are many causes of a false positive which include liver disease, blood tranfusions, infections, autoimmune disease and dumb luck! ...Read more

Hep B Virus (HBV) DNA Qualitative (Detection) - COBAS TaqMan , Hep C RNA Detection by Taqman detection will be conclusive on 47 days? Any retest need?

Dr. John Fung Dr. Fung
3 doctors agreed:
Hep B Virus (HBV) DNA Qualitative (Detection) - COBAS TaqMan , Hep C RNA Detection by Taqman detection will be conclusive on 47 days? Any retest need?

No: Both Hepatitis B and C viruses may be detected 30 to 60 days after infection by antigen detection or 60-120 days with antibody testing. Direct HBV DNA and HCV RNA testing can potentially detect infection earlier, within 2-4 weeks after infection, so being tested at 47 days post-exposure with a negative nucleic acid test for both is very likely to be a true negative ...Read more
