First, you need to know what’s in your blood that could be the source of your allergies. 2 labs are used to isolate the problem:

1. CBC with Diff for Eosinophil count. Looking for a high count. Can indicate allergy exposure or parasites.
2. Immunocap or RAST Test to isolate your allergens. Then avoid or make lifestyle changes

Probiotics help with cell immunity from the gut.
