Yes, you can perform an at-home allergy test. Several companies offer at-home allergy test kits. These kits typically involve a simple finger-prick blood sample that you collect and mail to a laboratory for analysis. Results are usually available online within a few days.
Types of At-Home Allergy Tests
While most at-home tests utilize a blood sample (measuring IgE antibodies, a key indicator of allergic reactions), it's crucial to understand that these tests don't cover all possible allergies. They usually focus on common allergens, such as those found in food or the environment. A skin prick test, while possible to perform a simplified version at home (using products you suspect as allergens), is not recommended without professional guidance.

Blood tests: These are the most common type of at-home allergy test. They require a small blood sample, often obtained via a finger prick. The sample is sent to a lab for analysis of IgE antibodies. Examples include tests from YorkTest and Everlywell. YorkTest and Everlywell offer such kits. These tests typically measure your IgE reactivity to numerous common allergens.

Patch tests (for skin allergies): While a simplified version can be done at home using a potential allergen on your skin, a proper patch test is best conducted by a healthcare professional.
Important Considerations:
- At-home tests are convenient but may not be as comprehensive as tests performed by a doctor or allergist.
- Results from at-home tests should be reviewed with a healthcare professional.
- At-home tests primarily focus on IgE-mediated allergies; they might not detect other types of allergies.
How At-Home Allergy Tests Work:
- Order a kit: Purchase an at-home allergy test kit online or from a pharmacy.
- Collect a sample: Follow the instructions to collect a sample, usually a finger-prick blood sample.
- Mail the sample: Return the sample to the laboratory using the provided prepaid envelope.
- Receive results: Access your results online once the lab completes the analysis.
