About this test
The ethylene oxide allergy test is a blood test that measures immunoglobulin E (IgE) antibodies against ethylene oxide, a gas widely used to sterilize medical equipment and in some industrial processes. It helps determine whether exposure to ethylene oxide is contributing to allergy symptoms such as sneezing, nasal congestion, itchy or watery eyes, wheezing, or skin irritation. Because ethylene oxide is a gas, reactions are usually linked to occupational or healthcare-related exposure rather than everyday contact. The test is typically ordered for sterilizer operators and others with recurring symptoms after exposure.
What this test measures
- Ethylene oxide-specific IgE Detects IgE antibodies that bind to ethylene oxide allergens in the blood.
Who this test may be right for
- Workers who operate or work near ethylene oxide sterilization equipment.
- Healthcare and laboratory staff exposed to sterilized devices and materials.
- People with asthma or rhinitis that worsens in sterilizer or industrial areas.
- Those being evaluated for suspected occupational chemical allergy.
Before your visit
- No fasting is required.
- Tell the clinician about antihistamines and any other allergy medications.
- Continue prescribed medications unless a healthcare provider advises otherwise.
- Wear a loose top or short sleeves for the blood draw.
Understanding your results
A positive result suggests the immune system has produced IgE antibodies to ethylene oxide, which may indicate a sensitivity contributing to respiratory, nasal, eye, or skin symptoms after exposure. A negative result makes ethylene oxide allergy less likely but does not exclude other workplace chemicals or irritants. Because this is a gas used in specialized settings, symptoms are usually tied to specific exposures. Discuss findings with a healthcare provider for context.

Where is ethylene oxide encountered?
It is commonly used to sterilize medical devices and in some industrial processes, so exposure is generally occupational or healthcare-related.
Is irritation the same as allergy?
No. Chemical irritation and IgE-mediated allergy are different, and this test specifically looks for an IgE antibody response.
What is the turnaround time?
Turnaround is typically 1-3 business days.
