Seafood Allergy Diagnosis

Seafood Allergy Diagnosis Research

The Department of Paediatrics is conducting a research study on diagnostic methods for shellfish allergy. We will use new molecular and cellular allergy tests to detect specific IgE antibodies against allergens derived from shellfish (crustaceans and mollusks) commonly consumed in Hong Kong. Shellfish includes: shrimp (seawater and freshwater shrimp), crab, scallop , mussels, clams, lobster, oysters and abalone.

 

We are now recruiting subjects who meet the following criteria to participate in our research:

- history of allergic reactions to shellfish

- children or adults aged 0-50 years

- presented immediate allergic reactions within 2 hours (such as urticaria, non-tubular swelling, wheezing, anaphylactic shock) upon shellfish ingestion

 

For eligible participants, we will arrange:

- an appointment to the Prince of Wales Hospital for a physical examination to determine the condition of allergies to shellfish

- collection of 8-10ml of whole blood for allergy blood test

- skin prick test

After completing the tests, we will provide written report of shellfish allergy test results.

 

If you meet the above requirements and are interested in participating in this research, please fill out the questionnaire at the following link:
