Hepatitis b surface antigen non-reactive means what?

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

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

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

Is a core positive antibody for hepetitis b is dangerous. Igm antibody negetive. Surface antigen negetive with surface antibody positive. Explain?

Past infection: The results you described are consistent with a past infection with hepatitis b from which you have recovered. You body made antibodies to the constituents of the virus. These results are not a cause for concern. ...Read more

Urine Culture Results 50,000-100,000 CFU/mL Staphylococcus coagulase negative not S.saprophyticus 10,000-50,000 CFU/mL Multiple organisms Meaning?

Urine Culture Results
50,000-100,000 CFU/mL Staphylococcus coagulase negative not S.saprophyticus
10,000-50,000 CFU/mL Multiple organisms
Meaning?

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, the colony count, the dominant organism and multiple organism all suggest that this is not real urinary infection. The organisms are likely to be skin contaminants. ...Read more

Hi Doc, had UTI test. Result: Epithelial cells 1-2/HPF, pus Cells 2-3/HPF, colony count 100,000 cfu/ml. Organism Isolated:Staphylococcus saprophyticus?

Possible UTI: The organism you described is a skin contaminant and is not considered a pathological bacteria it is not the bacteria that has given you a bladder infection. If you have pain on urination or pain around the belly you may have a bladder infection these values in your urine analysis are not diagnostic of a UTI. ...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

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

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
