The cost of an allergy test will depend on what kind of allergy test you're getting.
For a blood allergy test it can cost from as low as $200.00 and as high as $1,000.00 and if you're getting tested for Chronic Allergies or Hives it can go up to $2,000.00 or more.
A skin allergy test is much cheaper and can cost from $60.00 to $300.00
Most health insurance will not cover these tests although some will. Be sure to check with your health insurance company to see if your health insurance will cover the cost of allergy tests because they can be expensive out of pocket.
