Tissue transglutaminase IgA resulted in 2.26. Igg resulted in .47. Does that necessarily mean I have celiac disease?

Looked normal: Iga ttg below 19 u is considered normal. Unless you had an IgA deficiency, i wonder why igg ttg was ordered? If you indeed had an IgA deficiency, then even the slightly positive igg titer would warrant hla genetic testing. If the figures provided were in units, then you do not have celiac disease.

Highly likely: Do note that your symptoms may not improve noticeably for weeks or months after avoiding gluten. So don't be impatient.
