What it measures
- Shrimp-specific IgE — reflects immune sensitivity to shrimp proteins
- Crab-specific IgE — reflects immune sensitivity to crab proteins
- Lobster-specific IgE — reflects immune sensitivity to lobster proteins
- Clam-specific IgE — reflects immune sensitivity to clam 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.

FAQ
Frequently asked questions
Does a positive result mean I am allergic to shellfish?
Not necessarily. Sensitization on a blood test can occur without symptoms, so a clinician considers your history, exam, and sometimes other testing before making a diagnosis.
Can this test tell the difference between crab, shrimp, clam, and lobster allergies?
The panel reports results for each shellfish separately, which may help identify which ones are more likely to be relevant. However, cross-reactivity is possible, and a clinician interprets the pattern.
Is this test safe?
This test uses a standard blood draw, which has minor risks such as bruising or discomfort at the collection site. It does not involve exposing you to shellfish.
When will results be ready?
Turnaround times vary by laboratory and test volume, but results are often available within a few business days. Your ordering clinician or lab can provide the expected timeline.
