Allergy Testing Q&A

Allergy Testing Richardson Texas

What happens when a person suspects an allergy?

If a patient believes they have had an allergic reaction, he or she will meet with Dr. Rahimi to discuss the symptoms, potential causes, and what testing or treatment is needed. The doctor examines the patient and asks detailed questions about the allergic symptoms to understand the situation. He may order a variety of tests to gather more information about the potential allergy. The results of these tests, including the presence of certain proteins in the blood or any rash-like reactions on the skin, would indicate an allergy. Most doctors agree that additional testing and monitoring is necessary to identify food allergies. The doctor may ask the patient to follow an elimination diet or keep a food diary including details of what has been eaten and any subsequent symptoms. Treatment can begin once the allergy is identified.

What happens during allergy testing?

The first step in an allergy diagnosis is the collection of the patient’s medical history and asking questions to determine if an allergy is the cause of the symptoms.  Next, a number of tests will be carried out to test for sensitivities to specific allergens. The doctor may order any number of tests including a skin prick test, blood test, oral food challenge and/or trial elimination diet.

During the skin prick test, the skin is lightly scratched or pierced and a drop of solution containing the allergen will be placed on the patient’s skin to enter the bloodstream. The tested area is then monitored for a reaction. A blood test involves a sample being drawn to measure the presence of IgE antibodies to known allergens. The presence of these antibodies indicate potential allergies. However, when testing for food allergies specifically, approximately half of blood and skin prick tests can result in a false positive. A positive result will indicate to the doctor that an oral food challenge, or an elimination diet, could help in further diagnoses.

What allergy testing method is best?

Skin and blood tests both have strengths and weakness. Skin tests provide fast results, however, some medicines can affect these tests and the results are sometimes hard to read on darker skin. Blood tests only involve a single needle prick, which is popular with many patients, but it can take a long time for the results to be returned. These evaluations are not the sole diagnostic tool used by the doctor when investigating potential allergies, but provide supporting evidence to other information gathered during the doctor’s exam.
