To diagnose food allergies, you must perform a full physical skin test as well as other diagnostic procedures, such as interviews, evaluations and counseling. You may also need to do some other diagnostics on skin and substubation to make sure you have an allergic reaction. You may also need to measure hemoglobin A1c levels through hemoglobin A1c to eliminate other base diseases.
