Unproven
allergy testing. The following are examples of unproven allergy
testing. This list is NOT intended to be all-inclusive:
• In vitro
histamine release.
• Provocative and neutralization
testing for food, environmental chemicals, inhalant allergens, and
endogenous hormones.
• Sublingual
testing.
• Cytotoxic leukocyte test for
food and inhalant allergies.
• Rebuck
skin window test.
• Passive transfer (Prausnitz-Kustner)
test.
• Serial skin-test end point
titration for routine testing.
• Kinesiology
testing. This test involves muscle strength measurements after food
ingestion or sublingual application of food extracts.
• Reaginic
Pulse test. This test measures the increase of pulse rates after
ingestion of a suspected allergic food substance.
• Enzyme-Linked
Immunoabsorbent Assay (ELISA).
• Electrodermal
diagnosis.
• Chemical analysis of body tissue.
• Recall
skin tests.
• In vitro lymphocyte proliferation.
• Food challenge
testing performed in connection with clinical ecology programs.
• Nitric
oxide expired gas determination (Current Procedural Terminology
(CPT) procedure code 95012) for asthma is unproven.
