Most Lyme-Literate physicians recommend a gluten-free diet during Lyme treatment anyway, no matter whether a person has Celiac/Gluten Sensitivity or not.
I was diagnosed with Gluten Sensitivity based on stool testing prior to being diagnosed with Lyme, but have had the Lyme for a long time. I personally believe, in those who have genetic susceptibility, that Lyme can turn "on" the genes and this can lead to gluten related issues...and I believe the same can be true for other autoimmune conditions as well.
If you tested that high and have been avoiding gluten, then you may still be getting exposed to gluten through some other means, such as hidden gluten ingredients, skin care products, cross-contamination with non-gluten-free foods (shared use of utensils, toaster ovens, nonstick pans, etc.), etc.
Here is a link to a list of where gluten can hide on ingredient lists:
Chronic Lyme Disease, Chronic Bartonella (clinical dx only), Gluten & Sulfite Sensitivity, Many Food/Inhalant/Medication/Chemical Allergies & Intolerances, Asthma, Gut issues (dysmotility, non-specific inflammation), UCTD ("Secondary Lupus-Like Syndrome"), Osteoporosis, chronic Lymphopenia, etc.; G-Tube; Currently weaning off TPN.
Meds: Pulmicort, IV Doxycycline, Heparin (to flush PICC line), Claritin, Singulair, Domperidone, Colloidal Silver (topically & nasally), probiotics, Liver support herbs, Ailanthus, digestive enzymes, homeopathy.
