Today, with serological testing (determination of coeliac disease-specific antibodies in the blood) and duodenal biopsy with histological testing being available for diagnosing coeliac disease, patients with suspected coeliac disease are strongly advised to undergo both serological and biopsy testing before undertaking a gluten-free diet.

Iron tests; Celiac disease screening; Urinalysis for blood cells, protein and glucose; In addition to the CDC's recommendation, the NICE guideline recommends HbA1c and creatine kinase tests, and mentions that blood tests for vitamins D and B 12, infectious diseases, and adrenal insufficiency may be warranted.

The results of a 2017 study suggest that non-celiac gluten sensitivity may be a chronic disorder, as is the case with celiac disease. [ 42 ] For people with wheat allergy , the individual average is six years of gluten-free diet, excepting persons with anaphylaxis, for whom the diet is to be wheat-free for life.
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
Anti-gliadin antibodies were one of the first serological markers for coeliac disease. Problematic with AGA is the typical sensitivity and specificity was about 85%. Gliadin peptides which are synthesized as the deamidated form have much higher sensitivity and specificity, creating 2 serological tests for CD that approach biopsy diagnostic in ...
Tests for the antibodies in the blood can be used clinically to help screen for celiac disease, IgA blood tests for both tTG and endomysial tTG can be effective ways to determine whether someone has Celiac disease, especially in more severe cases, although for more common, mild forms of Celiac, these tests are less effective.
Most attention to anti-transglutaminase antibodies is given with respect to celiac disease. A recent study of children published in 2007 demonstrated that the level of ATA in correlates with the scalar Marsh score for the disease in the same patient. [9] High levels of ATA are found in almost all instances of celiac disease. [10]
In Europe, DQ8 is associated with Type 1 diabetes and coeliac disease (also known as celiac disease). The highest risk factor for type 1 diabetes is the HLA DQ8/DQ2.5 phenotype. In parts of eastern Scandinavia both DQ2.5 and DQ8 are high increases frequencies of late onset Type I and ambiguous Type I/II diabetes.
