I have been reading about this test, I am supposed to go for one on day 8 after AF. Now I am worried though because years ago I was told that I am allergic to shrimp & other shellfish after I was having allergic reactions out of the blue. I am honestly really not sure that this is accurate. (I have Crohn's disease & my specialist thinks that my system was just whacking out- not actually true allergies). Now I'm nervous that I won't be able to have the test. What do you think? Any advice/info would be appreciated. I'll call my dr. on Monday. Thanks!
