Allergy Testing at Freedom Allergy

At Freedom Allergy, we provide a full range of testing to accurately diagnose allergies and sensitivities in both children and adults. Identifying the right triggers is the first step toward lasting relief.

Skin Prick Testing (Allergy Skin Testing)

Skin prick testing is the most common way to diagnose environmental and food allergies. A small drop of allergen extract is placed on the skin (usually the forearm or back), and the skin is gently pricked.

• Quick results: Reactions typically appear within 15–20 minutes.

• What it diagnoses: Pollen, dust mites, mold, pet dander, and food allergies.

• Why it matters: Helps confirm triggers that may be causing asthma, allergic rhinitis, eczema, or food reactions.

At Freedom Allergy, we use pediatric-friendly techniques to keep children comfortable during testing.

Blood Testing (Allergen-Specific IgE Testing)

For patients who cannot undergo skin testing, blood tests provide another reliable way to detect allergies.

• When it’s used: If you have eczema, take antihistamines, or cannot stop certain medications before testing.

• How it works: A small blood sample is sent to the lab to measure allergen-specific IgE antibodies.

• What it diagnoses: Food allergies, environmental allergies, medication allergies, and more.

• Benefits: Convenient, safe, and does not involve exposure to allergens during testing.

Blood testing can also help track allergy severity over time and monitor progress during treatments like oral immunotherapy (OIT) or allergy shots (immunotherapy).

Patch Testing

Patch testing is used to identify delayed allergic reactions, often linked to contact dermatitis. Instead of pricking the skin, allergen patches are applied to the back and left in place for 48 hours.

• What it diagnoses: Reactions to metals (like nickel), fragrances, preservatives, hair dye, latex, and other chemicals.

• Process:

  1. Patches are applied on Monday.

  2. Removed and checked on Wednesday.

  3. Final reading is done Thursday or Friday.

• Why it matters: Patch testing helps uncover hidden triggers of rashes, skin irritation, or eczema flares.

Sensitivity Testing (Food and Environmental Sensitivities)

Some patients experience symptoms that are not caused by classic IgE-mediated allergies. In these cases, we offer sensitivity testing and a thorough evaluation to uncover less obvious triggers.

• Food sensitivities: May cause bloating, headaches, or fatigue.

• Environmental sensitivities: May worsen asthma, eczema, or chronic sinus symptoms.

• Approach: We combine history, elimination diets, and lab testing to create a personalized care plan.
