2. How can a blood test help me know if I have allergies?
If you have allergies, your body produces an antibody called IgE that is specific to your allergic triggers. The blood test measures the amount of your IgE. Your healthcare provider can use your test results to identify the specific allergic triggers that may be contributing to your symptoms. Your specific IgE test results are as personal and unique as your fingerprint. After you receive your test results, you should review them with your healthcare provider and create a tailored plan to help reduce your exposure to your specific allergic triggers.
