Do not undertake genetic testing for coeliac genes as a screening test for coeliac disease

The value of testing for coeliac genes is primarily as a negative test – if the gene test is negative then coeliac disease may be excluded. However as a coeliac gene can be found in approximately one third of the population, a positive result does not make coeliac disease a certainty. Serological testing, in a patient consuming an appropriate amount of gluten, is the appropriate first line screening test for coeliac disease. A small bowel biopsy is then required if serology is positive.

How this list was made How this list was made

The Gastroenterological Society of Australia (GESA) initially engaged its members through its regular online communications, sharing the aims of the EVOLVE initiative, as well as background information on the US and Canadian versions of Choosing Wisely. Members were provided with a copy of the five recommendations made by the American Gastroenterology Association. GESA also consulted externally, with the EVOLVE Lead Fellow addressing the GUT club and the Inflammatory Bowel Disease Group on the initiative. All members of GESA were invited to submit proposed items for the Top 5 list. The GESA Council reviewed all items before reaching consensus on the recommended final list. A review of the evidence for the shortlisted items was then undertaken and the final list and its rationales were signed off by the GESA Council in May 2016.
