Possible limitations in new celiac testing methods
Dr. Maureen Leonard of the Center for Celiac Research and Treatment of Harvard Medical School in Boston said studies are being conducted on screening celiac disease for people who are on a gluten-free diet, but these tests may be beneficial for people with a specific genetic background. This may be due to the hereditary characteristics of celiac disease. In this light, it is important for people to have themselves tested for celiac disease before they go on a strict gluten-free diet.
Dr. Leonard added that the tests are not yet clinically available. Due to this, additional work is needed to make them more accurate and make them available for clinical use. Dr. Leonard also said a duodenal biopsy may be necessary to confirm the presence of celiac disease. It should be noted that Dr. Maureen Leonard was not a part of the team of Dr. Sarna.
