Food Allergies

What’s your feeling regarding blood testing versus skin prick testing for IgE allergies? From what I’ve read, there can be false positives in both.

Male patient, 52 years old, three years out from traumatic brain injury after a skiing accident with three prior concussions. How do I treat balance and ringing in the ears as his primary complaint. Wanted to continue to eat gluten, so I ran Cyrex 4 and didn’t come back with anything. His cholesterol is low at 135. LDL is 77, HDL 41. I told him about fat and cholesterol for the brain.

Micronutrient testing low in B12 shown by no red meat and high MCV, also low folate B2 and B5 even though he’s on a B complex in addition to B12 methyltetrahydrofolate.

Chris: That’s a really good question, and I’ve asked Cyrex that a few different times, and their response is basically...
