Skin tests are more sensitive than blood tests, but we might use a blood test to diagnose allergies if:
Your blood sample will be tested for the antibodies of specific allergens that show if you have allergies. It takes a few days to receive blood test results.
Our allergists are experts at choosing which allergens should be tested, examining the results, and helping you find the right treatment for relief.
The skin prick test is used for treatment purposes, whereas the blood test has many false positives along with being tremendously expensive.
