How to measure anti-dna antibody using farr assay?

How to measure anti-dna antibody using farr assay?

Radioactivity: The farr assay is a radioimmunologic assay. It uses radiolabeled antigens to detect specific antibodies in serum. The antigens are allowed to react with the serum and then precipitated using a special reagent such as protein a sepharose beads. The bound radiolabeled immunoprecipitiate is commonly analzyed by gel electrophoresis. ...Read more

Is Lab Corp ANA direct as accurate as ANA IF?

Is Lab Corp ANA direct as accurate as ANA IF?

Accurate?: The ANA is fraught with technical difficulties, but it's also critical that you understand how nonspecific a positive ANA is, even at a fairly high titer like 1:160. Perhaps one older person in 4 has a positive ANA and it proves nothing -- the vast majority of healthy. It's only one piece of a diagnostic puzzle. Hope this helps -- if not please repost and let us know exactly what' s up. ...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.

My rubella IgM ELISA value is 0.05 UI/ML, CMV IgM ELISA value is 0.16 UI/ML, CMV IgG value is 6.8 UI/ML, and Rubella IgG value 39.8 UI/ML. is it safe?

My rubella IgM ELISA value is 0.05 UI/ML, CMV IgM ELISA value is 0.16 UI/ML, CMV IgG value is 6.8 UI/ML, and
Rubella IgG value 39.8 UI/ML. is it safe?

Depends on range: If the IgM values are within the lab's normal range, then this means you have had previous exposure or vaccination. If the IgM is well above the lab's normal range, then possibly you have recently been infected or vaccinated. Talk to the doctor who ordered the tests, and make sure to discuss the issue of false positives. ...Read more

Which of these 3 hep c antibody screening  tests(methodology)is the most accurate: Architect Anti-HCV,  Advia Centauer HCV or Roche Eclia?

About equal: All three methods are FDA approved and about equally accurate. If you have concern about active Hep C infection, get a Hep C nucleic acid test. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually.

What is HIV antibody test accuracy?

What is HIV antibody test accuracy?

HIV testing: Yes. Of course it is. That is as long as you have allowed enough time to past for your body to produce antibodies against the HIV if you are infected. If you are not infected then if you only test with the HIV antibody test, you must wait six months after exposure for it to be fully reliable and accurate if you test negative. The situation in reality is that no one need wait that long ...Read more

Ebvab VCA IgM <36 (range 0-35.9), ebvearly antigenab IgG 37 (0-8.9), ebvab VCA IgG >600 (0-17.9), EBV nuclearantigenab IgG 409 (0-17.9) mono? No mono?

You had mono...: Your mono-like symptoms likely prompted the testing- i hope you are starting to feel a little better. Testing for different antibodies (igm and igg) against ebv, requires careful interpretation. In early phases of infection, the igm level peaks first followed by a decline; levels of igg peak afterwards, and may remain elevated for quite a while. ...Read more
