Allergy test results indicate whether you have a specific allergy. A positive result means you're allergic to a particular substance, while a negative result means you're not. However, false positives and negatives can occur, so it's crucial to discuss your results with a healthcare provider.

The numbers on allergy test results range from 0.00 to 100.00, indicating the level of specific IgE antibodies in your blood. A result above 0.35 is generally considered positive, while higher numbers indicate a stronger allergic reaction. Each allergen is measured individually.

Allergy testing identifies allergens, like mold, pet dander, bee stings and peanuts, that can cause allergies. A skin prick test, blood test and oral food challenge are common allergy tests. The results can help diagnose allergies and help you take steps to manage allergy symptoms.

Takes days or weeks to get results because the blood sample must be sent to a laboratory for evaluation; skin testing provides immediate results. These tests can be hard to interpret and are often reported as low to high-probability allergies.
