Summary
New assays like Western blot, CAST, and Flow CAST help diagnose hymenoptera sting allergy when conventional tests fail. These methods detect basophil activation, improving diagnosis for patients with unexplained anaphylaxis.
Area of Science:
- Immunology
- Allergy Diagnostics
Context:
- Increasing cases of hymenoptera sting anaphylaxis with negative conventional IgE tests.
- Limitations of traditional diagnostic methods for insect sting allergies.
Purpose:
- Review the principles and diagnostic value of novel assays for hymenoptera sting allergy.
- Address the diagnostic challenge posed by unexplained anaphylaxis to insect stings.
Summary:
- Explores advanced diagnostic techniques including Western blot, Cellular Antigen Stimulation Test (CAST), and Flow CAST for hymenoptera sting allergy.
- These assays measure basophil activation through mediator release (histamine, leukotrienes) or cell surface marker detection.
- Highlights their utility in cases where standard IgE testing yields negative results.
Impact:
- Improves diagnostic accuracy for hymenoptera sting allergy.
- Offers alternative testing strategies for patients with suspected allergy but negative conventional tests.
- Enhances understanding of basophil activation in allergic reactions.
