Allergen, Occupational, Isocyanate HDI
Also known as: ISO HDI
Use
This test is used for the quantitative detection of IgE antibodies specific to occupational allergen Isocyanate HDI. It assists in identifying clinical allergies related to exposure to isocyanate, a chemical commonly used in various industrial applications. The test measures the IgE levels and provides a scoring system that correlates with the probability of an IgE mediated clinical reaction. It is important to correlate the laboratory results with clinical history and possible in vivo reactivity to make accurate clinical decisions.
Special Instructions
Separate serum from cells as soon as possible or within 2 hours of collection. Transfer to an ARUP Standard Transport Tube. For multiple allergen orders, refer to 'Allergen Specimen Collection Instructions' at www.aruplab.com/testing/resources/specimen.
Limitations
Results indicating allergen-specific IgE levels may not always correlate with the severity of allergic reactions experienced by the patient or skin test results. The detection of IgE antibodies can sometimes fail to predict clinical allergy or even anaphylaxis. Concentrations of allergen-specific IgE within the range of 0.10–0.34 kU/L are of undetermined clinical relevance and should be further interpreted by specialists.
