Does cytotoxicity testing diagnose food allergies?

ANSWER

That's controversial. Scientists have done several studies on this and found that it doesn’t work. In cytotoxicity testing, a food allergen is added to a sample of someone's' blood. A technician then examines the sample under the microscope to see if white cells in the blood die.
