The Industrial Allergy Test Panel for automotive and manufacturing measures immunoglobulin E (IgE) antibodies against several occupational chemicals: ethylene oxide, and the isocyanates MDI, HDI, and TDI. These substances are used in automotive, plastics, foam, and coating industries, and airborne exposure can contribute to respiratory symptoms such as sneezing, cough, wheezing, or chest tightness. This panel helps assess whether your symptoms may be linked to a workplace allergen. Results are interpreted with your occupational history, exposure levels, and protective measures.

• Ethylene Oxide-specific IgE Measures IgE antibodies that react to ethylene oxide, used in sterilization and chemical manufacturing.
• Isocyanate MDI-specific IgE Measures IgE antibodies that react to MDI, an isocyanate used in foams and coatings.
• Isocyanate HDI-specific IgE Measures IgE antibodies that react to HDI, an isocyanate used in paints and coatings.
• Isocyanate TDI-specific IgE Measures IgE antibodies that react to TDI, an isocyanate used in foam production.

• Workers in automotive, plastics, foam, or coating industries with new respiratory symptoms.
• People whose provider suspects an occupational or industrial allergy trigger.
• Individuals exposed to isocyanate-containing paints, adhesives, or foams at work.
• Anyone with work-related sneezing, cough, or wheezing that improves away from the job.
• People being evaluated for allergic asthma linked to workplace exposures.

• No fasting is required.
• Continue your usual medications unless a healthcare provider advises otherwise.
• Pause antihistamines before testing only if your provider instructs you to, as they may affect some allergy results.
• Describe your job tasks, the chemicals you work with, and any protective equipment used.

The report lists a separate IgE level for ethylene oxide and for the isocyanates MDI, HDI, and TDI. A higher level may suggest sensitisation to that agent, while a low or undetectable level makes allergy less likely. Occupational allergy is best interpreted alongside your work history and the timing of symptoms, since exposure levels and protective measures matter. IgE testing cannot confirm a diagnosis alone. Discuss any positive or unexpected result with a healthcare provider, and consider involving occupational health resources where appropriate.
