Why timing matters
Coeliac serology and the usual diagnostic pathway depend on the person consuming gluten. Coeliac Australia explicitly warns that avoiding or restricting gluten before testing can produce inaccurate results [1]. Coeliac Australia puts a number on it: gluten avoided for more than about six weeks before testing is enough that gluten has to be eaten again before the tests mean anything. How much, and for how long, is a decision for the clinician arranging the testing.
That creates an unusual boundary for a gluten-free cooking site: helping someone cook after diagnosis is useful, but persuading an undiagnosed reader to remove gluten “to see what happens” can interfere with the very testing needed to establish the diagnosis.

A positive blood test is not the finish line
Coeliac Australia notes that antibody results on their own should not be used to diagnose coeliac disease, and that diagnosis is made by a gastroenterologist; diagnosis should be confirmed through the appropriate specialist pathway [1]. The ACG guideline similarly addresses formal diagnosis and ongoing management [3].
A recipe site therefore does not interpret antibody values, gene tests or biopsy results. Its role starts with food support, not diagnostic adjudication.

If gluten has already been removed
People who have already restricted gluten may need a clinician-guided approach to testing. The appropriate gluten challenge, if any, is a clinical decision rather than a recipe instruction.
The site can explain why the problem exists but should not prescribe bread quantities or challenge duration to an individual reader.

After diagnosis
Once coeliac disease is established, strict gluten-free eating becomes the relevant food-management framework and practical cooking guidance has a clear purpose [2].
That is where the future cookbook will operate: ingredient eligibility, normal household cross-contact controls and satisfying recipes, while medical monitoring stays with the reader’s care team.
