Skin Testing With Carefree
Skin allergy testing identifies how your immune system reacts to specific allergens by introducing small, controlled amounts to the skin and observing localized reactions. This in-office testing provides same-day results and helps pinpoint environmental and select food triggers so treatment decisions can be made without delay.
At Carefree Allergy, skin testing is performed and interpreted by our nurse practitioner, Lindsey Forstie, who has specialized education and clinical training in allergy and asthma care. Her expertise ensures testing is purposeful, accurately interpreted, and directly connected to personalized treatment planning.
Types of Skin Allergy Testing We Offer
The type of test used depends on your symptoms, history, and the suspected allergy type.
Skin Prick Testing
The most common method for evaluating immediate allergic reactions. Small amounts of allergen are placed on the surface of the skin to assess reactions to environmental allergens and certain foods. Results are available during the visit and help guide same-day treatment decisions.
Intradermal Injection
A more sensitive form of skin testing used when additional diagnostic clarity is needed. A small amount of allergen is injected just beneath the skin — most often to further evaluate environmental allergies when skin prick testing results are inconclusive.
Each testing method serves a specific purpose, and results are always interpreted in the context of your symptoms to ensure an accurate and clinically meaningful diagnosis.
How Skin Testing Works
Clear, accurate answers in a single visit whenever possible.
Focused Evaluation
Your visit begins with a review of symptoms, reaction timing, and medical history to determine which skin testing method is most appropriate.
Targeted Skin Testing
Testing may include skin prick testing for common environmental or food allergens, and intradermal testing for more detailed environmental assessment. Testing is performed in the office with close monitoring.
Same-Day Results & Next Steps
Results are reviewed the same day and used to guide treatment decisions, with findings incorporated into a personalized care plan.
How to Prepare for Skin Testing
Proper preparation helps ensure accurate results. Certain medications and conditions can interfere with skin reactions.
- 1
Stop antihistamines prior to testing
Antihistamines can suppress skin responses and lead to inaccurate results. This includes many over-the-counter allergy medications and some cold or sleep aids. Our office will provide a specific list and timeframe before your visit.
- 2
Continue other medications unless directed otherwise
Most asthma inhalers, nasal sprays, and prescription medications can be continued. Always confirm with our office if you are unsure.
- 3
Wear comfortable clothing
Choose something that allows easy access to your arms or back, where testing is typically performed.
- 4
Eat, drink, and arrive well hydrated
If you are ill, experiencing a skin flare, or have had a recent severe allergic reaction, testing may need to be rescheduled.
Understanding Your Skin Test Results
Both skin prick testing and intradermal testing require a short observation period, typically 15 to 20 minutes, to monitor the skin's response. During this time, the skin is evaluated for raised, red, itchy areas known as wheals. The size of the wheal helps indicate the degree of sensitivity to a specific allergen.
After testing, results are reviewed with you in detail. Lindsey Forstie will explain how your findings relate to your symptoms and daily exposures, review which allergens are most relevant, and outline practical next steps.
Based on your results and symptom severity, a personalized treatment plan is recommended. This may include environmental strategies, medication adjustments, or long-term allergy treatment options like sublingual immunotherapy.
