Hiv ab,1/2, eia with relx result repeatedly reactive. HIV 1/2ab differentiation w/refl hiv1 antibody negative hiv2 antibody negative. pos or neg hiv?

It depends: In a situation like this you have one positive test and one negative test. The lab should run a tie-breaker test (HIV RNA) to give you a real answer. Also, the first test may be an older test 2nd or 3rd generation) instead of the latest 4th generation) test. It also depends on if you have flu-Like symptoms. Seek help from a specialist in HIV who can help you understand. ...Read more

Hepatitis c (HCV) antibody is reactive. The hepatitis C Recombinant Immunoblat Assay(riba) confirmation test is non reactive.Is antibody false positiv

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. Do a Healthtap visit or see a primary care physician for specific diagnosis ...Read more

Test results: hepatitis Be Ab non-reactive Hepatitis Be Ag: negative Hepatitis Bs Ag: non reactive Quantitative HBV PCR : detected What it means?

Test results:
hepatitis Be Ab non-reactive
Hepatitis Be Ag: negative
Hepatitis Bs Ag: non reactive 
Quantitative HBV PCR : detected 
What it means?

See below: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, from what you provided, you could have an early stage infection with hepatitis B. More than 80% of the people recover from the infection on their own. Discuss it with the doctor who ordered the test. ...Read more

Clostridium difficile toxin b gene present
clostridium dificile antigen presen. Would u no how severe the c diff is?

Have diarrhea or no?: C.Difficile is pathogenic in older children & adults (whose colonic microflora are altered by antibiotics, chemotherapy, salmonella/shigella). C.Diff causes diarrhea w/pseudomembranous & other colitis, complicates inflammatory bowel disease, causes fulminant transmural extension, perforation with peritonitis, toxic megacolon. Treatment, & confirmation of post-treatment eradication, is recommended. ...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

05/05/2016 Siemens Advia Centaur hep C antibody result positive.08/10/2016 Abbott Architect (cmia) hep C antibody result negative.Who is telling truth?

It's not really: a question of truth telling. No test is perfect: the proteins and reactants used in each test will respond to an individual's blood/biologic material, potentially, in a different way. Falsely positive or falsely negative results are not very unusual. You need to decide on a confirmatory strategy with your doctor. Retesting is necessary and an expert can help you weigh the evidence to decide result ...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

Had EBV test came back EBV nuc IgG ser qi eia positive and EBV vac IgG eia postive. Ebv capsid IgM eia negative. I'm so tired what do this mean?

Makes perfect sense: Igm antibodies rise only during the actual, acute infection. They then fade away and are replaced by the various igg antibodies, which are the ones that provide lifetime protection against the same strain of the virus. So your numbers are consistent with the fact you had mono years ago. There is no igm, and positive igg levels. So you are immune and do not currently have mono. ...Read more

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
