Comprehensive Allergy Testing in Richardson: How Johnson Medical Associates Finds the Root Cause of Your Symptoms
If you’ve been dealing with unexplained symptoms — recurring sinus issues, skin reactions, digestive problems, or respiratory flare-ups — allergies may be the hidden culprit. Many patients in the Richardson and Dallas–Fort Worth area spend years cycling through treatments without ever identifying what they’re reacting to, because standard testing only scratches the surface.
At Johnson Medical Associates, Dr. Alfred Johnson takes a comprehensive, root-cause approach to allergy diagnosis and treatment. With over 35 years of experience in internal and environmental medicine, he and his team use advanced testing methods to pinpoint the specific substances triggering your symptoms — so you can finally get real, lasting relief.
Watch: Dr. Johnson Explains Our Approach to Allergies
Why Traditional Allergy Treatment Often Falls Short
Conventional allergy care usually involves a basic skin scratch test and an antihistamine prescription. But for many patients, symptoms persist because the full spectrum of allergic triggers has never been identified. Standard scratch tests can miss subtler sensitivities, and over-the-counter medications only mask symptoms without addressing the underlying cause.
As Dr. Johnson explains, allergies can be the underlying cause of many unexplained symptoms — affecting your ears, nose, throat, lungs, skin, and even your gastrointestinal tract. The key is identifying exactly which substances you react to so treatment can be targeted and effective.
Our Comprehensive Approach to Allergy Diagnosis and Treatment
At Johnson Medical Associates, we go well beyond standard allergy testing to build a complete picture of your sensitivities:
1. Intradermal Skin Testing
Unlike standard scratch tests, our intradermal technique tests one item at a time, allowing us to observe cause-and-effect relationships and measure the severity of each reaction with precision. This method is significantly more sensitive and provides a clearer picture of your specific environmental allergies — including pollens, dust, and molds (both indoor and outdoor).
2. Food Sensitivity Testing
Many patients don’t realize that the foods they eat every day could be driving their symptoms. Food sensitivities can trigger reactions in your ears, nose, throat, lungs, and gastrointestinal tract. At JMA, we use specialized blood testing to identify food-related immune responses that standard allergy panels miss entirely.
3. Chemical and Metal Sensitivity Testing
Through stool testing, blood testing, and patch testing, we identify sensitivities to chemical substances and metals you may encounter in your daily life — from workplace exposures to cosmetics, fragrances, and other chemical products. These often-overlooked sensitivities can be the missing piece for patients with persistent, hard-to-explain symptoms.
4. Personalized Treatment Plans
Once we’ve identified your specific triggers, we develop a targeted treatment plan. This may include allergen avoidance strategies, immunotherapy to build tolerance over time, and environmental modifications — all tailored to your unique sensitivity profile and daily life.
