i did, many years ago. for me the skin prick test was the best. i tried others involving blood like RAST, and either was negative or was positive to things I’m not allergic to. If you do the skin prick test, make sure you go to a doctor that has a large list of foods available. One Doc I went to only had like 15 foods. My allergies have gotten worse since I started killing candida. must have opened the holes up bigger. apparently you can heal them once you kill candida and heal the gut. Raster has done it. he’s awesome.
