Good to knowOne result rarely tells the whole story. Your provider looks at your results together with your symptoms, exam, and other tests.
What the test is
A positive test doesn't always mean a true allergy; results are read with your history. Large food panels without symptoms can be misleading.
Why it's done
- Allergy symptoms that are hard to control
- Reactions to foods, insect stings, or medicines
- Planning allergy shots
Getting ready and what happens
- Stop antihistamines several days before skin testing, if asked.
How the test is done
- Skin test: tiny amounts are pricked into the skin, and bumps are checked after 15 minutes.
- Blood test: a regular draw.
What the results mean
Positive
Shows sensitization. Your allergist decides whether it explains your symptoms.
When a result needs quick action
Call 911Trouble breathing, throat swelling, or fainting after exposure. Use epinephrine if prescribed.
Questions to ask your provider
- What do my results mean for me?
- Do I need to repeat this test or have other tests?
Risks
A blood draw is very safe. You may have slight pain or a small bruise where the needle went in.
