A shrimp allergy test is a blood test that checks for allergic antibodies to shrimp proteins. It is ordered when a person has had allergic symptoms after eating shrimp or other shellfish, or when a clinician needs to confirm or rule out a shrimp allergy.

What it measures

  • Shrimp-specific IgE — Antibodies made by the immune system that target shrimp proteins.
  • Total IgE — A general measure of allergic antibody levels in the blood.
  • Component allergens (e.g., tropomyosin, arginine kinase) — Specific shrimp proteins that can help show which part of shrimp triggers reactions.

Who it is for

A primary care clinician, allergist, or immunologist typically orders this test. It is used for adults or children with a history of reactions after eating shrimp or other shellfish.

Preparation

No fasting or special preparation is needed. The blood sample can be collected at any time of day.

Results and what they mean

Results are reported as a number or class for each antibody measured, often with a reference range. A clinician interprets these results alongside your symptoms and history; a positive test alone does not always mean you have a shrimp allergy. This is general information and not medical advice.

Requesting the Shrimp Allergy Test in California

Order online, choose a certified collection site in California, and review results through a secure portal. No referral is required, and orders are processed confidentially. Because the region is uneven, coastal metros, inland towns, and rural counties with very different access to testing — worth planning around when you book.

Frequently asked questions

Does a positive test mean I am definitely allergic to shrimp?

Not always. Some people have positive antibodies without symptoms. Your clinician will consider your history and may recommend further testing.

Can I eat shrimp if my test is negative?

A negative test makes allergy less likely, but it does not rule it out. Talk with your clinician before trying shrimp again, especially if you have had a severe reaction.

Is this test safe?

Yes. It uses a standard blood draw and does not expose you to shrimp, so it cannot cause an allergic reaction.

How long do results take?

Results are usually available within 1 to 3 business days.
