Polymerase Chain Reaction (Definition)

Polymerase chain reaction is a method of finding a specific piece of dna and copying it over and over again until there is enough to study. The technique allows a scientist to detect very small amounts of dna in a swab sample then reproduce enough of it to study it. It is very sensisitive for detecting the presence of certain bacteria and is also used in doing other ...Read more

What happens if HBsAG is positive,hbc antody positive ,hbe antibody positive ,hbe antigen not detected.am I hepatitis free?

What happens if HBsAG is positive,hbc antody positive ,hbe antibody positive ,hbe antigen not detected.am I hepatitis free?

Have hepatitis B, c?: HbsAg, is the antigen of the hepatitis B virus. You have antibodies to the core antigen of the virus (Hbc) and hepatitis e virus; absence of Hep e antigen means that you may have lost that virus. You were exposed to hepatitis C, or you have that infection too. See see a hepatologist (a gastroenterologist who has special interest/training in liver diseases. ...Read more

Ask who ordered: The test, but in general, they were suspecting EBV infection/Infectious mononucleosis, which looks negative, the final diagnosis is with the doctor who ordered the blood test. Clinical picture is important, finally we treat patients not lab results, good luck ...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

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

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

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

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

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

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

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

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

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

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
