We had the intradermal skin test done because the dermatologist we went to said that was her preference and she thought it was a much more exact test than the blood test.
The testing cost $440 and the first vial of allergy serum (which lasts about 5 months or so cost $200). Serum refills are about $160. This is what she looked like after the skin test:
