What this test is
This is a blood test that looks for immunoglobulin E antibodies tied to oranges, limes, lemons, tangerines, and grapefruits. It is used to help evaluate possible citrus allergy when symptoms suggest a reaction. Results are reported as allergen-specific IgE levels for each fruit.
What it measures
- Orange-specific IgE — reflects sensitization to orange proteins
- Lime-specific IgE — reflects sensitization to lime proteins
- Lemon-specific IgE — reflects sensitization to lemon proteins
- Tangerine-specific IgE — reflects sensitization to tangerine proteins
- Grapefruit-specific IgE — reflects sensitization to grapefruit proteins
What the test involves
A healthcare professional collects a small blood sample, usually from a vein in your arm. The sample is sent to a laboratory for analysis, and no special preparation is typically required beyond what the collection site advises.
Why it is often ordered
A clinician may order this panel when a person reports symptoms after eating or handling citrus fruits, such as itching, hives, or digestive upset. It can also be used to help clarify whether citrus is a likely trigger among several possible allergens.
Preparation
Follow the instructions provided by the laboratory or collection site, as preparation can vary. If you take medications or have other health conditions, ask the lab or your clinician whether any changes are needed before testing.
How results are reported
Results are reported as a level for each citrus allergen, often with a qualitative interpretation such as negative, low, or elevated. Reference ranges and reporting formats differ by laboratory, so results should be reviewed with a clinician who knows your history.

FAQ
Frequently asked questions
Does a positive result mean I am definitely allergic to citrus?
No. A positive result shows sensitization, which means your immune system has made IgE antibodies to that fruit, but it does not always cause symptoms. A clinician interprets the result together with your symptoms and history.
Can this test tell me how severe a reaction will be?
No. The level of specific IgE does not reliably predict how severe a future reaction might be. Severity depends on many factors, and only a clinician can assess your risk.
Do I need to avoid citrus fruits before this test?
Usually no special avoidance is needed for an IgE blood test. Follow any instructions from the laboratory or your clinician, since they may have specific guidance for your situation.
How long does it take to get results?
Typical turnaround is a few business days after the sample reaches the laboratory. Actual timing can vary by laboratory and collection site, so ask them for an estimate.
