Allergen, Food, Pumpkin Seed IgE
Also known as: PUMPKIN
Use
This test is used to determine the presence and concentration of specific IgE antibodies to pumpkin seed allergen, which can help assess the likelihood of an IgE-mediated allergic reaction in patients. The results, expressed in kU/L, reflect the concentration of allergen-specific IgE in the serum and are categorized into different class scores, indicating the probability of an IgE mediated clinical reaction. However, these concentrations may not correlate directly with clinical symptoms, and clinical correlation with patient history and in vivo allergen reactivity is essential.
Special Instructions
Multiple patient encounters should be avoided for accurate allergen testing. Separate serum from cells as soon as possible and transfer it to an ARUP standard transport tube following collection. Avoid hemolyzed, icteric, or lipemic specimens. It is critical that clinician correlation be applied, especially with results in the indeterminate range as these are meant for specialist interpretation.
Limitations
The test does not provide a definitive diagnosis of allergy, as a negative result does not rule out clinical allergy or even anaphylaxis. The test has not been cleared or approved by the FDA and is intended for clinical purposes in a CLIA certified laboratory. The correlation between the measured IgE levels and the clinical response or skin testing results when exposed to the specific allergen may not always align, emphasizing the need for clinical correlation with patient history.
