Anaphylaxis after prick-to-prick test with fish.

Area of Science:

• Allergy diagnostics
• Clinical immunology
• Pediatric medicine

Background:

• Skin prick testing (SPT) is a common method for diagnosing allergies.
• The prick-to-prick method is frequently used, especially for suspected food allergies.
• SPT is generally considered a safe diagnostic procedure.

Observation:

• A pediatric patient underwent SPT using the prick-to-prick method with raw fish.
• The patient had a history of consuming fish without prior allergic reactions.
• Anaphylaxis, a severe allergic reaction, occurred during the testing procedure.

Findings:

• The case demonstrates a rare but serious risk associated with SPT, even in patients without a known history of reactions to the allergen.
• Prick-to-prick testing with raw fish can precipitate severe allergic reactions like anaphylaxis.
• Individual patient factors may influence the risk of allergic reactions during SPT.

Implications:

• Allergy testing, including SPT, requires careful patient selection and risk assessment.
• Healthcare providers must be prepared to manage anaphylaxis during allergy testing.
• Enhanced vigilance and cautious protocols are necessary for safe skin prick testing, particularly in pediatric populations.
