Ana (Definition)

An "ana" is a blood test used to screen a person for the possibility of several autoimmune diseases.

What is the difference between the anachoice screen and the ANA screen, ifa? The first one came back positve, but the second came back negative.

IFA better: For a screen the ifa is much better. It is the gold standard. The ANA choice is not a screening test and should not be offered as a screening test. Your question is somewhat counter intuitive. The ifa is a better test and if choice is positive - it can be subseted into 12 antigens and the lab can tell you. I would follow your test results with ANA subsets per your rheumatologist. ...Read more

What is the difference between the anachoice screen and the ANA screen, ifa? The first one came back positve, but the second came back negative.

Diff. lab techniques: Different labs have different ANA tests, which is a test for antibodies a person makes that attach to his own body's tissues, that end up causing auto-immune disease. Modern tests use "reflex" or "cascade" techniques, meaning one test is done first, and then if positive, another test is done, and then if positive again, a third test is done. Tests have various "positive" ranges (gets complicated). ...Read more

What does titer with 180H with ANA IFA positive and homogeneous pattern mean?

ANA explanation: ANA are antinuclear antibodies which are seen in Systemic Lupus and some other disorders. Titer means how many dilutions in the test are still positive.

Why would ANA direct be positive 3 years, but then IFA method be negative? Scl70 antibodies were elevated and still are at 5.2! Direct false then?

ANA are being check : With two methods currently, one with ELISA, which is cheaper and more commercially available and read by machine. The other one with IFA, which is less prevalent, more expensive, more labor intense as it is interpreted by trained technician and of course the accuracy is better with latter. Scl70 antibody is important but without positive history and physical finding it is almost meaningless. ...Read more
