About this test

This test uses a total IgE reading to help assess whether you may be reacting to shellfish, covering eight commonly eaten types according to Medichecks. A raised IgE result is commonly used as one signal of allergic sensitisation, though on its own it does not identify which specific shellfish is responsible.

The listed panel is a single biomarker, below the 2-marker median across the 19 tests in its comparison group, while the £299 price sits exactly at the group's median. Broader options are available elsewhere in the group: YorkTest's Food Allergy Test covers 42 allergens for £139, and Check My Body Health's Food & Environmental Allergy Test covers 117 for £159.99, though neither is marketed as shellfish-specific in the way this one is.

Clinical depth scores lower here because the panel is narrower than the group's typical count, while value for money is roughly average given the price matches the median. Collection convenience is middling, requiring a venous draw with a home nurse option. Trust signals are consistently strong across Medichecks' range: a solid Trustpilot rating, UKAS ISO 15189 accredited partner labs, doctor review as standard, and a company history stretching back to 2001.

Who is it for?

This suits you if you have had a reaction after eating shellfish and want a focused test with a doctor's comment on the result, at a price typical for this type of screening.

If you would rather test a wide range of foods rather than shellfish specifically, YorkTest's Food Allergy Test (42 allergens, £139) or Check My Body Health's broader panels cover considerably more ground for less money.

How it works

The sample is a venous blood draw, collected at a Medichecks clinic, via a home nurse visit, or at another clinic offering the venous draw option; there is no self-collected at-home version. The lab measures IgE activity associated with shellfish reactions. Results are typically ready in around 5 days and a doctor reviews them before you receive your report.

Pros & cons

Pros

  • Focused specifically on shellfish, rather than a broad general panel
  • Doctor review included with the result
  • Priced exactly at the median for its comparison group, so not a premium option

Cons

  • Lists only one biomarker, below the group's typical count of two
  • YorkTest and Check My Body Health test many more allergens for less money
  • Requires a venous draw rather than a self-collected sample
