How is celiac sprue diagnosed?
Doctors use information from your medical and family history, a physical exam, a dental exam link, and medical test results to look for signs that you might have celiac disease and should be tested. Doctors typically diagnose celiac disease with blood tests and biopsies of the small intestine.
What labs diagnose celiac disease?
tTG-IgA and tTG-IgG tests The tTG-IgA test is the preferred celiac disease serologic test for most patients. Research suggests that the tTG-IgA test has a sensitivity of 78% to 100% and a specificity of 90% to 100%.

What is a positive tTG IgA result?
Positive results for tissue transglutaminase (tTG) IgA antibodies are consistent with a diagnosis for celiac disease and possibly for dermatitis herpetiformis.
What is the difference between tTG IgA and tTG IgG?
There is also an IgG tTG test but it is less accurate than the IgG DGP test. Conversely, IgA tTG is more accurate than IgA DGP. The Endomysial Antibody test (EMA) is an earlier version of the tTG test. It is not as widely available as tTG and is more expensive than tTG.
Is celiac sprue the same as celiac disease?
Celiac disease, sometimes called celiac sprue or gluten-sensitive enteropathy, is an immune reaction to eating gluten, a protein found in wheat, barley and rye. If you have celiac disease, eating gluten triggers an immune response in your small intestine.
What is a celiac sprue biopsy?
A skin biopsy is sufficient for diagnosis of both DH and celiac disease. This biopsy involves collecting a small piece of skin near the rash and testing it for the IgA antibody.
Does high IgG mean celiac?
What does it mean if your t-Transglutaminase (tTG) IgG result is too high? The finding of tTG IgG antibodies may indicate a diagnosis of celiac disease, particularly in individuals who are IgA deficient.
What is a normal tTG IgG level?
Optimal IgG-tTG threshold levels differed between the IgA-deficient subjects (5.5 U/ml) and the IgA-sufficient subjects (2.5 U/ml). The observed overlap in IgG-tTG levels in the range from 2 to 8 U/ml (Fig.
What does a positive tTG IgG mean?
The finding of tTG IgG antibodies may indicate a diagnosis of celiac disease, particularly in individuals who are IgA deficient. For individuals with moderately to strongly positive results, a diagnosis of celiac disease is possible and the patient should undergo a biopsy to confirm the diagnosis.
