Insurance may cover the cost of an allergy test, so that can make the test much more affordable for many patients. You can contact us here at Suburban Healthcare Associates to see whether we work with your particular health insurance provider. We likely do, as we work with most major providers. Also, keep in mind that costs vary depending on the provider and the number of allergens being tested for. With insurance coverage, a test will likely cost somewhere around $70. Again, this cost varies depending on many factors. The cost of a blood test can be around $250, but this test is often more thorough and precise.
