Allergy Skin Testing
Allergy skin testing is the most sensitive form of allergy testing and continues to be the benchmark used by most allergists to diagnose the cause of allergies. A large number of allergy cells or mast cells reside in the skin providing a very accessible area to diagnose allergies. Allergy skin tests can identify allergic antibody to substances that can cause an allergic reaction (pollens, molds, dust mite, animal danders, foods and stinging insects). We use standard extracts from national companies and have the ability to make custom extracts for testing. Skin testing is done by the prick or intradermal method.
An alternative to skin testing is blood testing (RAST) which has a lower sensitivity but it is very useful in patients who have severe skin disorders or eczema on their back making skin testing difficult or if there is a history of severe, life-threatening reactions to certain substances.
