My serum test is negative for endomysial antibody  iga, ttg tissue transglutasminase iga, gliadin antibody igg. But positive for gliadin  antibody iga?

Treat the person: Lab tests mean nothing in isolation, and have many false positives and false negatives. The decision to make a trial of a gluten-free diet will be between you and your gastroenterologist or dermatologist based on the big picture. ...Read more

My ELISA anti rubella IgG negative(0.13 ul/ml) and ELISA anti rubella IgM positive(>400). Is it safe to pregnancy. ?

No: Igm rubella indicates recent exposure and body response to it. It does not refer immunity. Hence baby at risk for congenital rubella. ...Read more

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

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

Hepb surface antigen positive, confirmatory test negative, antibody and core negative, should I worry?

Hepb surface antigen positive, confirmatory test negative, antibody and core negative, should I worry?

Possibly: Do not understand how initial test was positive and "confirmatory" test negative. Need to repeat these, although you may be in the "window" period, when antigen is being consumed by forming antibody and neither is measurable. Wait 3 months and retest antibody titers. By then you may be hepb antibody and core antibody positive, in which case you are immune. ...Read more

What do these results mean? Hbsag positive, hbs ab negative, hbeag negative, hbeab positive and hbc ab positive?

What do these results mean? Hbsag positive, hbs ab negative, hbeag negative, hbeab positive and hbc ab positive?

This is serious: It is likely that you are infected with two different hepatitis viruses and need to be under the care of a physician who's willing to explain lab results and get you treated. Please don't let this go. Your life may well depend on your being appropriately assertive. ...Read more

Can an HIV antibody screening test be positive but the western blot negative?

Can an HIV antibody screening test be positive but the western blot negative?

Yes: There are 2 reasons for this kind of result: (1) a false positive, or (2) early infection before seroconversion. In someone at low risk for HIV without symptoms, another negative WB in 1 month means there's no infection. In someone at risk or with symptoms of acute infection, a viral load can be helpful. The new 4th generation antigen/antibody tests will eliminate this problem. ...Read more

Sm/rnp antibody- ANA choice- positive, speckled/titer: 1:1280; sm & rnp (done alone) negative; sm/rnp antibody (together?) positive 3.0 guessing mctd?

Sm/rnp antibody- ANA choice- positive, speckled/titer: 1:1280; sm & rnp (done alone) negative; sm/rnp antibody (together?) positive 3.0 guessing mctd?

Heads up: One of the things that's frustrating about these antibody tests looking for different connective tissue diseases is that they are difficult to do and are fraught with pitfalls. I suspect you've had at least one lab error to complicate your workup. Have you have a tube test for u1-rnp? Your clinical symptoms and signs actually tell more about your diagnosis ; best direction for treatment. ...Read more

ANA positive SSA SSB weekly positive SCL weekly positive RNP SM weekly positive. Any implications? What are the differential diagnosis? WaDoes it mean

Pos auto ab tests: You are describing positive tests for auto antibodies. The differential diagnosis can be extensive. I am assuming a rheumatologist has ordered these tests? You need f/u with them to educate you what they mean, what further tests may need to be done and review your symptoms. Proper rheum DX is not based only on test results, but exam findings and symptoms of patient. Good luck. ...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

What would cause a high positive ANA (1:640) speckled, nucleolar with a low positive smooth muscle antibody (1:40) but negative SS-A, SS-B, anti-Smith, RNP, SCL-70, Anti Jo antibodies? Liver disease?

What would cause a high positive ANA (1:640) speckled, nucleolar with a low positive smooth muscle antibody (1:40) but negative SS-A, SS-B, anti-Smith, RNP, SCL-70, Anti Jo antibodies? Liver disease?

Probably normal: Many people have a positive ANA without being sick. If you also have elevated liver enzymes, a workup for autoimmune hepatitis may be continued, but if there's nothing to suggest a liver problem biochemically, I'd not be in a hurry to diagnose despite anti-smooth-muscle. ANA means nothing apart from the clinical picture. Best wishes. ...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

Plz interpret. ANA via ELISA 74 units, strong positive (negative via IFA) Anti-Cardiolipin IgG 22 CU, moderate positive others neg. symptom fatigue?

Short answer is : Needing more info on labs and clinical symptoms. ANA positive is sensitive for possible autoimmune disease.but not very specific. Every lab on your ENA panel is important esp they are moderate positive and they all mean something different. Lab is never enough for diagnosis esp rheumatic condition. It is important for you to find a rheumatologist for thorough history and physical exam. ...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

4 hsv-2 type-specific IgG tests.1 partner for all. 1st=negative. 2nd test @7mo.=positive 3.3igg. 3rd test @11mo=negative. 4th test@21mo. = negative?

Lab Error: I would chalk this up to lab error, but in my patients we do not leave it there. There is a much better and more valid test to be done called a western blot test for herpes. This definitive test should have already been offered to you so that you can know for a fact whether you have herpes or not. ...Read more
