Recently, my health has been a bit tricksy: my Reynaud's Syndrome has been acting up in the evenings, not just when it gets really cold outside; I have a low-grade headache almost every day, beginning about 2 hours after I wake up; I'm now intolerant to milk; and my the left-hand gland in my neck - the one just below the jawline, you know where - is swollen and tender as a... um... tender gland.
So I went to my internist at the Baylor Healthcare Cartel, today to calmly present her with a laundry list of bothersome symptoms - including inability to comprehend and remember information like architectural theory, severe fatigue coupled with an inability to sleep, etc. - and she sat there for a minute and stared at me. Just stared.
I then informed her that, when I was tested for celiac disease by my neurologist over year ago, I tested negative. But OF COURSE I would test negative, because - in order for that test to work - the tested person has to be consuming gluten, something I had ceased to do some two months prior to the test. (I almost referred to myself as a test-ee, but that just sounded wrong, particularly when used in the plural).
After the little "IgA test doesn't work if you're not eating gluten" discussion, she decided to send me to a rheumatologist, because she's stumped. Also, it would be incredibly harmful to my health if I were to begin eating gluten, again, in order to take the IgA test, so that's out of the question.
