A broad autoimmune screen in one draw: ANA, rheumatoid factor and anti-CCP; celiac antibodies (tTG IgA) with total IgA to confirm the result is reliable; and thyroid antibodies with free T3. Antibody screens are reported as negative or positive rather than scored. A positive result is not a diagnosis — it is a finding to review with your provider.
ANA screen, rheumatoid factor, anti-CCP, tTG IgA, total IgA, TPO antibodies, thyroglobulin antibodies and free T3.
A positive antibody screen is a finding, not a diagnosis. Some antibodies, including ANA, are found in a share of healthy people. Any positive result should be reviewed with a licensed provider, who can decide whether further testing is needed.
The celiac test (tTG IgA) relies on IgA. If your total IgA is very low, the celiac test can read falsely negative, so total IgA confirms the result is reliable.
Yes. For the celiac antibodies to be accurate, keep eating gluten as normal before the test. If you have already cut gluten out, discuss timing with your provider first. No fasting is required.
