The Ultimate Guide To Allergy Testing In Adults: What To Expect, Prep Tips & Results - McGovern Allergy And Asthma Clinic

If you’re experiencing chronic congestion, sneezing, itchy skin, or unexplained reactions, getting an adult allergy test is one of the most effective ways to understand what’s triggering your symptoms. At McGovern Allergy and Asthma Clinic in Houston, the board-certified allergists help adults pinpoint allergens and create personalized treatment plans based on science-backed testing.

What Is Allergy Testing?

Allergy testing identifies substances—called allergens—that trigger your immune system. For many adults, symptoms develop gradually over time, making professional allergy testing in Houston essential for accurate diagnosis.

Allergy tests can identify sensitivities to:

  • Pollen
  • Dust mites
  • Pet dander
  • Mold
  • Foods
  • Insect stings
  • Medications

Types of Allergy Tests

Understanding the right test for your symptoms is key. At McGovern Allergy, our board-certified allergists choose the most effective method based on your history.

  1. Skin Prick Testing

One of the most common and reliable test types, SPT involves placing a tiny amount of allergen on your skin—usually your forearm or back—and lightly pricking the surface. If you’re allergic, a small bump (similar to a mosquito bite) appears within 15–20 minutes.

Best for:

  • Environmental allergies (pollen, mold, pet dander)
  • Some food allergies
  • Dust mite allergies

 

  1. Blood Testing (Specific IgE Tests)

A simple blood draw measures allergen-specific IgE antibodies. This test is ideal for people who can’t undergo skin testing.

Best for:

  • Patients on antihistamines
  • Those with skin conditions like eczema
  • Those with a high risk of severe reaction

 

  1. Patch Testing

Patch testing checks for delayed allergic reactions—mainly contact dermatitis. Small patches containing potential allergens are placed on your skin for 48 hours.

Best for:

  • Metal allergies
  • Fragrances
  • Preservatives
  • Latex

How to Prepare for an Adult Allergy Test

  1. Stop Antihistamines Ahead of Time

Most antihistamines must be stopped 3–7 days before skin testing (your allergist will give exact timing). They can interfere with results.

  1. Bring a List of Symptoms

Logging when your symptoms flare—season, location, foods eaten—helps your allergist pinpoint patterns.

  1. Wear Comfortable Clothing

Some tests require access to your arms or back.

  1. Share Your Full Medical History

Be sure to tell your provider about:

  • Current medications
  • Past reactions
  • Asthma history
  • Skin conditions

 

What Happens During the Appointment?

Consultation, History, and Exam

Your allergist will review your symptoms, medical history, and environmental factors (home, work, exposures). Your allergist and medical team will then perform a physical examination.

Testing Procedure

Depending on the type of test, you may undergo one or multiple methods during your visit.

Results & Personalized Plan

Skin test results appear within minutes. Blood test results return within days.

Your provider will discuss:

  • Identified allergens
  • Avoidance strategies
  • Medication options
  • Whether immunotherapy (allergy shots) is recommended

 

When to Consider Adult Allergy Testing

Consider testing if you experience:

  • Long-term congestion or sinus infections
  • Unexplained rashes or itching
  • Worsening seasonal allergies
  • Suspected food reactions
  • Asthma flare-ups
  • Chronic cough
  • Reactions to pets or mold

The right diagnosis can dramatically improve your quality of life.
