Celiac Disease Screening Test

This test is only for adults aged 18 and older.

An estimated 2% of people with celiac disease also have selective immunoglobulin A (IgA) deficiency. If someone has IgA deficiency and celiac disease, the IgA deficiency can cause a false negative on a celiac disease antibody test. However, those with IgA deficiency should be tested for celiac disease because they are 10 to 20 times more likely to develop an autoimmune response to gluten than the general population.

To navigate a false positive, those with IgA deficiency should be tested for IgG-tTG antibodies instead of IgA-tTG. That's why we include the IgG-tTG antibodies testing in our celiac screening test. Please note, like any celiac disease blood test, you will have to go back to eating gluten regularly for at least 6 weeks prior to testing - of course, please see a doctor if you are suffering a severe allergic reaction when consuming gluten.

 No, at this time you can only be diagnosed with an upper endoscopy biopsy, which is prescribed and carried out by a medical professional. A positive celiac disease screening result with imaware™ provides accurate likelihood based on a lab analysis of 4 key biomarkers. If likelihood is high, your results report can be used to engage with a gastroenterologist to continue along on your path to a diagnosis.

Unfortunately, yes. Your blood test (and subsequent small intestinal biopsy) will not be accurate if you are not eating enough gluten. You'll need to go back to a gluten-containing diet for at least 6 weeks for any blood test to be valid. If you have an allergy to wheat or consuming any amount of gluten makes you very ill, please consult with a physician first.

The celiac disease screening test is for those that are still eating gluten, designed to provide a scale of likelihood that someone has the disease. The celiac disease monitoring test, on the other hand, is for those already diagnosed with celiac disease who want to make sure their biomarker levels are declining into a normal range with a strict gluten-free diet. The monitoring test measures the effectiveness of a gluten-free diet based on your biomarkers trending down over a period of time¹².

Your imaware™ celiac screening test results will tell you how likely you are to have celiac disease. A blood test is only the first step to diagnosis, but it will provide a clear indicator of likelihood. Results that indicate a high likelihood of having celiac disease can be used to engage with a gastroenterologist for an endoscopy and biopsy to confirm active celiac disease.

This test is ideal for anyone experiencing:

• Regular digestive distress
• Unexplained weight loss
• Fatigue
• Itchy skin rash 
• Unexplained anemia 

Anyone with a family history, specifically a first-degree relative with celiac disease, should be screened for celiac disease regularly since it increases your risk of having the disease.

Yes. All of our tests are performed by CLIA-certified labs, the gold standard in lab testing quality regulation. Within your results report you will also find detailed information intended for your healthcare professional. They can use this information to interpret your test results clearly.
