The RAST is a radioimmunoassay test to detect specific IgE antibodies to suspected or known allergens for the purpose of guiding a diagnosis about allergy. [10] [11] IgE is the antibody associated with Type I allergic response: for example, if a person exhibits a high level of IgE directed against pollen, the test may indicate the person is allergic to pollen (or pollen-like) proteins.
Allergy testing can help confirm or rule out allergies and consequently reduce adverse reactions and limit unnecessary avoidance and medications. [1] [2]Correct allergy diagnosis, counseling and avoidance advice based on valid allergy test results is of utmost importance and can help reduce the incidence of symptoms, and the need for medications and improve quality of life.

A commonly known and very basic test is the arm-pull-down test, or "Delta test," where the patient resists as the practitioner exerts a downward force on an extended arm. [16] Proper positioning is paramount to ensure that the muscle in question is isolated or positioned as the prime mover, minimizing interference from adjacent muscle groups.
Candidates must have a minimum of an associate degree from a respiratory therapy education program supported by the Committee on Accreditation for Respiratory Care (CoARC) to be eligible for the TMC Examination. Credentialed practitioners may then apply for state licensure. [4] [5]
A person receiving a skin allergy test. A microscopic amount of an allergen is introduced to a patient's skin by various means: [1] Skin prick test: pricking the skin with a needle or pin containing a small amount of the allergen. [2] Skin scratch test: a deep dermic scratch is performed with help of the blunt bottom of a lancet. [3]
