What this test is

This test measures immunoglobulin E (IgE) antibodies that your immune system may make in response to lime proteins. It is a blood test used to evaluate possible allergy to lime or related citrus fruits. The test does not diagnose allergy by itself; it is interpreted alongside your symptoms and history.

What it measures

  • Lime-specific IgE antibody — Reflects immune system sensitization to lime proteins.
  • Total IgE (if included) — Provides a general measure of allergic antibody levels, though it is not specific to lime.
  • Citrus cross-reactive markers (if included) — May indicate sensitivity to related citrus fruits such as lemon or orange.

What the test involves

A healthcare professional collects a small blood sample, usually from a vein in your arm using a standard blood draw. The sample is then sent to a laboratory for analysis.

Why it is often ordered

A clinician may order this test when someone reports symptoms such as itching, hives, swelling, or digestive upset after consuming or handling limes. It is typically used as part of a broader evaluation for food or citrus allergy.

Preparation

Preparation is usually minimal, but you should follow the instructions provided by the collection laboratory. Ask the lab if any medications or foods need to be avoided before your sample is taken.

How results are reported

Results are reported as a numerical level of specific IgE antibody, often with a qualitative interpretation such as negative, low, or high. Reference ranges and reporting formats vary by laboratory, so your clinician will interpret your result in the context of your symptoms.

Before you go

  • Whether any medications or foods should be avoided before the blood draw.
  • How and when you will receive your test results.
  • Whether additional citrus or food allergy tests are being ordered at the same time.
