If you live in North Texas, you know that allergy season is not just a season. It is practically a year-round event. From cedar fever in the winter to pollen in the spring and ragweed in the fall, dealing with a constant runny nose, itchy eyes, and sinus pressure can drain your energy. Many Highland Village residents rely on over-the-counter antihistamines just to get through the day. But if you want longer-term relief, you need to know exactly what is triggering your symptoms. That is where environmental allergy testing comes in.
The Process: How Long Does It Take?
A lot of patients put off allergy testing because they assume it will be a long, painful, and drawn-out process. The good news? An environmental allergy test usually takes less than 30 minutes.
Here is what the appointment looks like:
Step 1: The Skin Prick Test (5 to 10 Minutes)
The most common and effective way to test for environmental allergies (like pollen, dust mites, mold, and pet dander) is a skin prick test.
- Your provider will clean an area on your back or forearm.
- Using a tiny, plastic device, they will gently prick the surface of your skin with small amounts of different allergens.
- Note: It is not a needle injection. It usually feels like a quick scratch.
Step 2: The Waiting Game (15 Minutes)
Once the allergens are applied, you will sit and relax for about 15 minutes. During this time, your provider is waiting to see how your skin reacts. If you are allergic to a specific substance, a small, raised bump (like a mosquito bite) will appear in that specific spot.
Step 3: Immediate Results
The best part about skin prick testing is that you do not have to wait days for a lab to call you back. The results are immediate. Before you leave the clinic, your provider will review which allergens you reacted to and discuss a customized treatment plan.
Before Your Appointment: A Simple Checklist
Most of your visit is the test itself, but a little planning helps you avoid delays or a rescheduled appointment.
- Call ahead and ask whether any of your current medications should be paused before skin testing. Antihistamines in particular can affect results. Never stop a prescription medication without talking to your clinician first.
- Bring a list of every medication, supplement, nasal spray, and eye drop you use.
- Jot down when your symptoms flare. In North Texas, it helps to note whether winter, spring, or fall is hardest for you.
- Wear a short sleeved or loose top so the testing area is easy to reach.
- Plan to stay for the full observation period so your provider can read each reaction accurately.
What You Might Feel During and After the Test
Most people describe skin prick testing as mildly uncomfortable rather than painful. The spots that react may itch or look like small mosquito bites for a while. Try not to scratch them so your provider can see each reaction clearly, and ask your care team how to look after the area once you leave.
Tell the staff right away if you feel lightheaded or short of breath, or notice swelling beyond the test area. Testing is performed under medical supervision so the team can respond if you have a stronger reaction. If you develop trouble breathing or throat swelling after you get home, call 911 or go to the nearest emergency room.
Is Allergy Testing Right for You?
Testing may be worth discussing with a provider if:
- Your symptoms last for weeks at a time or return every season
- Over-the-counter options help less than they used to
- Congestion or sinus pressure is affecting your sleep or work
- You want to know whether pollen, dust mites, mold, or pet dander is the main issue before making changes at home
If you are not sure, a short consultation can help you decide. Book an allergy testing visit online, or call a clinic with questions first. Revive also offers food allergy testing, which you can discuss with your provider. Learn more on our allergy testing page, or read about the symptoms that often lead people to get tested.
Finding Real Relief
Knowing your triggers is the first step. From there, your provider might recommend lifestyle changes, prescription medications, or immunotherapy (allergy shots/drops), which is designed to help your immune system become less reactive to specific allergens over time.

Questions Highland Village Patients Often Ask
How long does an allergy skin test take?
A skin prick test usually takes less than an hour, according to Cleveland Clinic. Placing the allergens takes about 5 to 10 minutes, according to the American College of Allergy, Asthma and Immunology, and reactions usually appear within 15 to 20 minutes, according to MedlinePlus. Most people get their skin test results during the same visit.
Do you have to stop taking antihistamines before an allergy test?
Yes, antihistamines can change skin test results, according to MedlinePlus. The American College of Allergy, Asthma and Immunology advises not taking them for 3 to 7 days before the test. Medicines such as asthma inhalers, montelukast, and nasal steroids usually do not need to be stopped. Ask your provider before pausing any prescription medicine.
Does an allergy skin prick test hurt?
Most people find it only mildly uncomfortable. The lancet does not go deep into the skin, and most people describe the feeling as a tiny pinch, according to Cleveland Clinic. MedlinePlus notes the test may cause very mild discomfort when the skin is pricked, and spots that react can itch for a while.
Is an allergy blood test or skin test better?
Skin testing is the method allergists prefer and is usually the most accurate, according to the American College of Allergy, Asthma and Immunology. Blood tests can still help because medicines do not affect their results. Skin prick results are usually ready during the visit, while blood test results sent to a lab may take a week or longer, according to Cleveland Clinic.
What does a positive allergy skin test mean?
A positive skin test means you may be allergic to that allergen, according to the American College of Allergy, Asthma and Immunology. A raised, red bump called a wheal forms at the test spot, and a stronger reaction suggests greater sensitivity, according to MedlinePlus. A positive result alone does not confirm an allergy, so a clinician reads it alongside your symptoms and history.
How long do allergy skin test bumps last?
Most symptoms from an allergy skin test clear up within one to two hours, although redness or bumps may last several hours, according to Cleveland Clinic. In some people the raised spots, called wheals, can last up to several days, according to Cleveland Clinic’s allergy skin test guide. Ask your provider how to care for the area afterward.
Can children get allergy skin testing?
Yes. Adults and children of any age can be tested for allergies, according to the American College of Allergy, Asthma and Immunology, and in children the allergens are usually placed on the back. Providers typically do not do skin prick testing on babies younger than 6 months, according to Cleveland Clinic, and a numbing cream is sometimes used for young children.
