What this test is
This test measures the amount of specific IgE antibody in the blood that reacts to shrimp proteins. It is a type of allergy blood test, sometimes called a specific IgE test or RAST. The result is used with a person's history and other findings, not by itself, to assess sensitivity.
What it measures
- Shrimp-specific IgE antibody — Reflects the amount of IgE in the blood that binds to shrimp proteins.
- Total IgE (if included) — Reflects the overall level of IgE antibody in the blood, which can be elevated in allergic conditions.
- Other shellfish-specific IgE (if panel) — Reflects sensitivity to related shellfish such as crab, lobster, or scallops when tested together.
What the test involves
A healthcare professional collects a small blood sample, usually from a vein in the 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 a person reports symptoms after eating shrimp or other shellfish, such as hives, swelling, stomach upset, or breathing trouble. It can also be used to help evaluate whether shrimp should be avoided or whether further allergy testing is needed.
Preparation
No special preparation is usually required for this blood test, but follow any instructions given by the collection lab or your clinician. If you take medications, ask the lab whether any of them could affect the test.
How results are reported
Results are reported as a numeric level of shrimp-specific IgE, often with a qualitative category such as negative, low, moderate, or high. Reference ranges and cutoffs vary by laboratory, so results should be interpreted in the context of your symptoms and medical history.
