How much you can expect to pay out of pocket for allergy testing, including what people paid in 2017. For a patient not covered by health insurance an allergy test typically costs $150 to $300 for a consultation with an allergist, plus $60 to $300 total ($3 to $5 per allergen) for the much more commonly used skin prick test, or $200 to $1,000 total ($10 to $20 per allergen) for a blood test known as a RAST test. Allergy testing usually is covered by health insurance. For patients covered by health insurance, typical out-of-pocket costs involve a copay for the doctor's visit. For example, this BlueChoice plan has a copay of $20 for a family doctor and $35 for a specialist. And this Aetna plan has a $35 copay for testing.
