In vitro diagnosis of anaphylaxis

Area of Science:

• Immunology
• Allergy and Clinical Immunology
• Diagnostic Medicine

Background:

• Anaphylaxis diagnosis requires safe and accurate methods, especially for severe reactions.
• In vitro diagnostics aim to minimize patient risk during diagnosis.
• Current methods include mediator measurement and specific IgE testing.

Purpose of the Study:

• To explore novel in vitro diagnostic techniques for anaphylaxis.
• To highlight the utility of mediator measurement and cellular tests.
• To emphasize the advantages of the basophil activation test.

Main Methods:

• Serial measurement of anaphylaxis-related mediators (e.g., tryptase, histamine).
• Serologic methods for detecting trigger agents (serum-specific IgE).
• Cellular tests measuring basophil mediator release and marker expression (basophil activation test).

Main Results:

• In vitro techniques provide risk-free diagnostic options for anaphylaxis.
• Measurement of mast cell mediators aids in understanding reaction dynamics.
• Basophil activation tests offer advantages for drug-induced anaphylaxis where specific IgE is unavailable.

Conclusions:

• In vitro diagnostics are valuable tools for anaphylaxis diagnosis.
• The basophil activation test is a promising alternative for specific drug allergies.
• Advancements in diagnostic techniques improve patient safety and diagnostic accuracy.
