Celiac Genetic Test

Celiac disease is lifelong intolerance to gluten, which damages the lining of small intestine. But it resolves once gluten is removed from the diet.

Celiac is highly restricted to those with DQ2 or DQ8 genes. Although not everyone who tests positive for the genes will have the disease, almost all celiac patients carry either one or both genes. The gluten intolerance test is an important step to identify this risk, especially in families with a history of celiac.

The celiac genetic test is an at-home test that checks for high-risk (DQ2, DQ8), medium risk (DQA1*05), and low risk (DQA1*03) genes. It uses a simple saliva swab that is rubbed against the cheek, inside the mouth, to collect a sample.
