Allergy Blood Test

In addition to skin testing, allergies can be diagnosed using a blood test. Examples include the radioallergosorbent test (RAST) or the ImmunoCap. They give information similar to the skin test. However, they are more expensive, may miss identifying some allergies, and also take longer to determine the results. The blood test can be used when a skin test would not be suitable. For example, it can be used when a person has a skin disease which does not allow skin tests to be done, or when taking an antihistamine or other medication that might affect skin test results.

Both skin and blood allergy test results must be interpreted by a physician who is experienced in diagnosing and treating allergies and who is familiar with your medical history.
