Negative celiac blood work when on a gluten-free diet

Katarina Mollo MEd, RDN, LDN
Q: If you have been gluten-free for 6 years after being diagnosed with celiac disease, can your blood work come back negative?


Yes, if you are on a gluten-free diet you ideally would want your blood work to come back at negative levels. Elevated antibodies indicate ongoing damage in the intestine; the most common cause of elevated levels is continued gluten exposure. Having undetectable levels indicate that the gluten-free diet is working well. Since you have been gluten-free for six years, it is not unusual to have undetectable levels of celiac-related antibodies. Note that having a negative blood result with a previously established diagnosis of celiac disease does not mean your celiac disease has resolved, but that it is well-controlled.
