This is used to evaluate for suspected environmental or seasonal allergies, food allergy, stinging insect allergy, and certain drug/medication allergies. During skin testing the suspected allergen is placed on the skin and the test results are read after 15 minutes. An allergen is a substance that can cause an allergic reaction. There are 2 methods for skin testing: prick skin testing and intradermal skin testing.

Prick skin testing: Individual solutions containing the suspected allergens are placed on the skin using a prick device. The test results are available 15 minutes later.

Intradermal skin testing: Individual solutions containing the suspected allergens are placed just underneath the surface of the skin using a small needle. The test results are available 15 minutes later.

Our allergist will determine which specific type of skin test is required.

All test results are interpreted by our allergist.

Avoid all antihistamines and sleep aids that contain antihistamines for 5 days prior to your appointment. The reason for this is that antihistamines will block positive skin test results, thereby making the results unreliable.

In addition to skin testing, some patients may require blood tests called specific IgE tests (also commonly known as RAST) to complete their allergy evaluation. Specific IgE tests can also be obtained in some situations where allergy skin testing is not appropriate. Such situations would include (a) when a patient cannot discontinue antihistamines or certain other medications that would affect skin test results, (b) patients with a condition called dermatographism (whereby scratching the skin causes hives), or (c) patients with skin rashes/lesions that prevent us from accurately reading the skin test results.

Your allergist will determine if you require blood tests and these test results will be interpreted by your allergist while taking into consideration your medical history and other findings from your evaluation.

Blood tests are also used to investigate certain other disorders of the immune system including angioedema (swelling episodes), chronic urticaria (hives),
and primary immunodeficiency disorders.

This is a type of lung function test that we use to specifically evaluate for asthma. Asthma often occurs in individuals who have allergies. Individuals who report symptoms or have exam findings that are suspicious for asthma will require spirometry.

During spirometry testing, you are asked to inhale deeply and then forcefully exhale quickly while blowing into a device that measures your lung function. You repeat this at least 3 times to ensure that the results are consistent. Lung function measures are recorded by the device (called a spirometer).
The results are interpreted by the physician.

This is performed in selected individuals to confirm a food allergy or to determine if they may tolerate a food that they are currently avoiding. Incremental doses of the food are given to the patient starting with a very small quantity. Each dose is followed by a period of observation and assessment prior to receiving the next dose. After receiving the final dose, the patient undergoes an additional observation period and final assessment. Due to the risk of developing an adverse reaction, all food challenges are performed under physician supervision.

This is performed in selected individuals to confirm a drug allergy or to determine if they may tolerate a drug that they are currently avoiding. Incremental doses of the drug are given to the patient starting with a very small dose. Each dose is followed by a period of observation and assessment prior to receiving the next dose. After receiving the final dose, the patient undergoes an additional observation period and final assessment. Due to the risk of developing an adverse reaction, all drug challenges are performed under physician supervision.
