Allergy Testing & Treatment: Get Relief with Expert Care at Health Express Clinics

At Health Express Clinics in Lewisville, we understand how frustrating and debilitating allergies can be. Whether it’s seasonal sneezing, food sensitivities, unexplained rashes, or recurring sinus issues—allergy testing and treatment can provide the clarity and relief you need.

As a board-certified family physician, I’ve spent over a decade diagnosing and treating allergies in children and adults. Our team works closely with local allergy specialists when needed, but many patients can get effective allergy care right here in primary care—without waiting weeks for a referral to an allergist.

What Are Allergies?

Allergies occur when your immune system overreacts to a harmless substance (an allergen), such as pollen, pet dander, certain foods, mold, or dust mites. This immune response causes inflammation in the nose, skin, lungs, or digestive system.

Common Allergens We See at Our Clinics:

  • Pollen (oak, cedar, ragweed—especially common in North Texas)
  • Mold spores (especially after rain/humidity)
  • Pet dander (cats and dogs)
  • Dust mites
  • Food allergens (milk, peanuts, shellfish, gluten, eggs)

“In the Dallas-Fort Worth area, I often see patients with year-round nasal congestion, itchy eyes, and fatigue caused by untreated environmental allergies. Most don’t realize how much better they can feel with proper testing and treatment.”
– Dr. Harveer Parmar, MD

    Top 5 Questions Patients Ask About Allergy Testing and Treatment

    1. Do I need to see an allergy specialist or allergist near me?

    Not always. Primary care doctors can manage many mild to moderate allergy cases—especially nasal, skin, and food allergies. At Health Express Clinics, we offer:

    • Initial allergy screening tests
    • Treatment for allergic rhinitis, sinusitis, eczema, asthma, and food sensitivities
    • Referrals to a board-certified allergist for complex or anaphylactic reactions

    We work with trusted allergy specialists in Lewisville and the greater DFW area for advanced testing and immunotherapy if needed.

    2. What types of allergy testing are available?

    There are several options, depending on your symptoms:

    • Skin Prick Testing (SPT) – Small amounts of allergens are placed on the skin to check for reactions (done by allergists)
    • Blood tests (IgE testing) – Available in-clinic; useful for food allergies, environmental allergens, or when skin testing isn’t possible
    • Patch Testing – Detects delayed skin allergies (e.g., to fragrances or preservatives)
    • Oral food challenge – Performed under supervision by a specialist when food allergy is suspected

    At our clinic, we typically start with IgE blood panels to screen for common allergens and interpret results based on clinical history and symptom patterns.

    3. Can I get allergy treatment online?

    Yes—online allergy treatment is possible for non-severe cases. Through our telehealth services, we can:

    • Review symptoms
    • Order blood tests at a nearby lab
    • Prescribe allergy medications (antihistamines, nasal sprays, etc.)
    • Send referrals to a local allergist if needed

    “Online allergy treatment has made care more accessible for working parents, students, and busy professionals. Many patients can get the help they need without stepping into a specialist’s office.”
    — Dr. Harveer Parmar, MD

    4. What treatments are available for allergies?

    Treatment depends on the type and severity of your allergies. Options include:

    • Avoidance strategies (e.g., using HEPA filters, dietary changes)
    • Antihistamines (cetirizine, loratadine)
    • Nasal corticosteroids (fluticasone, mometasone)
    • Leukotriene inhibitors (montelukast)
    • Allergy shots (immunotherapy) – through local allergy specialists
    • Sublingual immunotherapy (SLIT) – drops or tablets under the tongue (for certain allergens)

    We start with first-line treatment in primary care and escalate to allergy specialists when needed.

    5. How do I know if I have a food allergy vs. food intolerance?
    • Food allergy involves the immune system, often with hives, swelling, vomiting, or anaphylaxis
    • Food intolerance is non-immune (e.g., lactose intolerance), with symptoms like bloating or diarrhea

    We use a combination of clinical history, IgE blood tests, and in some cases, elimination diets or referral for oral food challenges to differentiate the two.

    Real-World Observations from Our Clinic

    At Health Express Clinics, we often see:

    • Children with eczema or chronic ear infections triggered by undiagnosed food allergies
    • Teens and adults with seasonal allergies worsening into sinus infections or asthma
    • Patients with chronic fatigue and brain fog later linked to uncontrolled environmental allergies

    One recent patient—a 32-year-old mother—was struggling with daily headaches, post-nasal drip, and sinus pressure. A blood allergy panel revealed sensitivity to mold and dust mites. We started nasal corticosteroids and advised bedroom environmental control—her symptoms improved within 2 weeks.

    “Many patients think they just have ‘bad sinuses’ when it’s actually allergy-related inflammation. Treating the root cause makes a world of difference.”
    – Dr. Harveer Parmar, MD

      When to Refer to an Allergy Specialist

      We refer to a board-certified allergist when:

      • Suspected anaphylaxis or severe food allergies
      • Poor response to standard medications
      • Need for allergy shots or oral immunotherapy
      • Evaluation of complex skin or medication allergies
      • Asthma not controlled by inhalers

      We have referral relationships with allergy clinics in Lewisville, Denton, Flower Mound, and Plano.

      Local Trends in Lewisville & North Texas

      Allergies are particularly common in our region due to:

      • Pollen seasons nearly year-round (cedar, ragweed, mountain juniper)
      • High mold counts following rain/humidity
      • Air pollution and construction dust
      • Pet ownership trends

      According to the Texas Allergy Index (2023), DFW ranks in the top 15 most challenging places to live with allergies in the U.S. That’s why allergy testing and treatment is a year-round service at our clinic.

      Addressing Common Misconceptions

      ❌ “I outgrew my allergies—I don’t need treatment anymore.”
      ✔️ Allergies can return or evolve over time. Adults can even develop new food allergies later in life.

      ❌ “Over-the-counter meds are enough for everyone.”
      ✔️ Not always. Chronic inflammation often requires daily prescription treatment or specialist care.

      ❌ “Online allergy treatment can’t be trusted.”
      ✔️ When done through licensed providers like ours, telehealth allergy care is safe and effective for many mild to moderate cases.

      Limitations of Current Allergy Testing

      While modern testing is helpful, it has limits:

      • False positives can occur, especially in blood IgE tests
      • Not all food reactions are IgE-mediated
      • Interpretation should always be combined with clinical history

      “I always tell patients—don’t panic if a test says you’re ‘positive’ for something. We look at the full picture before making any diagnosis or restriction.”
      – Dr. Harveer Parmar, MD
