Histamine (Positive Control): A positive control is used to verify that the skin reacts normally.
Saline (Negative Control): A negative control ensures the skin doesn’t react to the liquid carrier itself.
What Conditions Does Skin Testing Diagnoses?
Skin prick tests are commonly performed to diagnose:
Allergic Rhinitis (Hay Fever): Sensitivities to tree/grass pollen, weeds, or mold.
Environmental Allergies: Reactions to dust mites, animal fur, or feathers.
Food Allergies: Reactions to peanuts, tree nuts, milk, shellfish, or eggs.
Insect Stings or Medication Allergies: Specific sensitivities to bee venom or certain drugs.
Treatment and Management After Testing
Once specific allergens are identified, a specialist can design an effective management plan, which may include:
Avoidance Strategies: Minimizing exposure to confirmed triggers.
Medication Management: Using antihistamines, nasal sprays, or emergency epinephrine (for severe food/sting allergies).
Immunotherapy (Allergy Shots or Drops): Gradual desensitization to train the immune system over time.
Disclaimer: Allergy testing should always be conducted and interpreted by a trained healthcare professional in a controlled medical environment to safely manage potential severe allergic reactions.
