About This Test
Allergy testing helps identify whether nasal, sinus, and eye symptoms are driven by specific allergens such as dust mites, pollens, molds, or pet dander. By turning general suspicion into specific information, testing supports clearer decisions about avoidance, medications, and whether immunotherapy is worth considering.
Testing is most useful when symptoms are persistent or hard to control, when triggers are unclear, or when immunotherapy is being discussed. At Norelle Health in New York City, allergy testing is offered as part of integrated ear, nose, and throat care, so results are interpreted alongside the nasal and sinus examination rather than in isolation.
This page explains what testing involves and how results guide care. It does not promise a cure; the plan depends on the examination, the testing results, medical history, and personal goals.
What Allergy Testing Is
Allergy testing identifies the specific environmental and seasonal substances that may be triggering nasal, sinus, and eye symptoms. By pinpointing triggers such as pollen, dust mites, mold, and pet dander, testing turns general suspicion into actionable information. The results help shape both avoidance strategies and targeted treatment, including whether immunotherapy may be appropriate.
Considering allergy testing? The next step is a quiet, unhurried conversation.
Why Patients Consider Testing
Patients often want to know whether their symptoms are truly allergic, which triggers are involved, and whether more than medication is needed. Testing is particularly helpful when symptoms are persistent or difficult to control, when avoidance has not been enough, or when immunotherapy is on the table. A positive test does not always explain every symptom, which is why results are interpreted in the context of the full evaluation.
How Norelle Health Evaluates Before Testing
Evaluation begins with a detailed history of when symptoms occur, what makes them worse, and what treatments have been tried, along with an examination of the nasal passages that may include nasal endoscopy. Because allergy frequently overlaps with sinus disease and nasal obstruction, the nose and sinuses are considered together. Testing is added when it will meaningfully change the plan rather than as a routine step for every patient.
How Testing Is Performed
Allergy testing is typically done in the office and may involve skin testing, in which small amounts of allergens are applied to the skin, or blood testing, depending on the situation. The approach is chosen based on history, current medications, and individual factors. Some medications, such as antihistamines, can affect skin testing, so you may be asked to pause them beforehand.
From Results to a Treatment Plan
Care is usually presented in escalating steps. Once triggers are identified, the plan may start with avoidance strategies and medications such as nasal sprays and antihistamines. When symptoms remain bothersome despite these measures, immunotherapy may be considered to reduce sensitivity to specific allergens over time. The goal is treatment tailored to the triggers that matter for you.
Risks, Limitations, and Alternatives
Allergy testing is generally low risk. Skin testing can cause brief itching or redness where allergens are applied, and significant reactions are uncommon when testing is performed under supervision. Testing identifies likely triggers but does not, on its own, dictate the entire plan, and a normal result does not always rule out a contributing cause. For some patients, a trial of treatment based on history is a reasonable alternative to formal testing.
What to Expect Afterward
Our New York City team reviews the findings and uses them to guide next steps, which may include avoidance measures, medications, or immunotherapy. Allergy care is usually managed over time rather than resolved in a single visit, with follow-up to confirm that the plan is working and to adjust it as needed.

Frequently Asked Questions
Skin testing typically involves brief, minor discomfort and itching where allergens are applied, and blood testing involves a standard blood draw. Most people tolerate testing well.
Some medications, such as antihistamines, can affect skin testing, so you may be asked to pause them beforehand. Your care team will give specific instructions based on your situation.
The choice depends on your history, current medications, skin condition, and individual factors. Your care team will recommend the approach that is most appropriate and reliable for your situation.
Testing identifies likely triggers, which helps guide avoidance and treatment, but the overall plan also considers your symptoms, examination findings, and preferences.
Not always. Many people do well with avoidance strategies and medications. Immunotherapy is considered when triggers are confirmed and symptoms are not adequately controlled by those measures, or when a patient prefers to address the allergy more directly.
Bring a list of your medications, any prior allergy test results, and notes on when and where your symptoms occur. Let the office know about your medications in advance, since some may need to be paused before skin testing.
Coverage varies by plan and medical necessity. We recommend confirming your benefits with your insurer, and our team can help guide the process.
