I’ve been tested several times in several ways for different forms of celiac and all have come back negative.
One problem is an on again, off again post nasal drip or chronic sinusitis ~ that's symptomatic of no lgE.
4-Way or other 2% solution nose sprays take care of the sinusitis. Then there's the wool allergy ~ it stinks! Literally. I've found other people don't smell the horrid odor of wool. Best to keep something between yourself and wool.
