Skin prick testing: Tiny drops of allergen extracts (like grasses, trees, molds, dust mites, and pet dander) are placed on your skin and gently pricked. Results appear within 15–20 minutes.
Intradermal testing: A small amount of allergen is injected just beneath the skin; used when skin prick tests are negative but suspicion remains high.
Patch testing: Patches containing potential contact allergens (e.g., fragrances, metals) are worn for 48 hours; used for rashes due to contact dermatitis.
Blood testing (specific IgE): A lab test useful when skin testing isn’t possible (e.g., extensive eczema, certain medications, pregnancy).

Many clinics ask you to pause for 3–7 days; confirm timing with the office.
Some antidepressants (e.g., tricyclics) and certain sleep aids have antihistamine effects; discuss with your clinician before stopping anything.

Skin testing: The clinician will place a panel of allergens carefully selected for LA’s environment. Mild itching or small hives at positive sites are common and temporary.
Observation: You will be monitored for 15–30 minutes. Results are read during the visit.
