Allergen, Insects and Venom, Yellow Jacket Venom
Also known as: YELLOW J
Use
This test measures the concentration of allergen-specific IgE antibodies for yellow jacket venom using ImmunoCAP technology. The results help assess the likelihood of IgE-mediated allergic reactions, which are typically immediate hypersensitivity responses. The clinical relevance of the specific IgE concentration must be interpreted in conjunction with the patient's clinical history and in vivo reactivity assessments.
Special Instructions
Multiple patient encounters should be avoided when collecting specimens. Clinicians should ensure proper separation of serum from cells and timely transportation under specified conditions to maintain specimen integrity. Additionally, reference to 'Allergen Specimen Collection Instructions' is suggested for precise specimen handling.
Limitations
The correlation between allergen-specific IgE concentrations and the degree of clinical response or skin testing results is not absolute. Results in the range of 0.10-0.34 kU/L have uncertain clinical relevance and should be interpreted with caution. Furthermore, a negative test result does not exclude the possibility of clinical allergy or anaphylaxis. It is crucial to interpret results in the context of the patient's clinical history and other diagnostic tests.
