The ethylene oxide allergy test is a blood test that checks for antibodies your immune system may make against ethylene oxide, a gas used to sterilize medical equipment and some spices. It is usually ordered when a person has allergic symptoms after contact with sterilized items or in certain workplaces.

What it measures

  • Ethylene oxide-specific IgE — The main marker; IgE is an antibody linked to immediate allergic reactions.
  • Total IgE — A general measure of allergic tendency, sometimes used for context.
  • Other specific IgE (optional) — May be added to check for related allergies if your history suggests them.

Who it is for

Allergists, immunologists, or occupational medicine clinicians typically order this test. It may be used for people with suspected reactions to sterilized medical devices or workplace exposure.

Preparation

No fasting or special preparation is needed. Tell your clinician about all medicines you take, especially antihistamines, as they may affect some allergy tests.

Results and what they mean

Results are reported as a level or class for ethylene oxide-specific IgE, often alongside total IgE. A clinician interprets these numbers with your symptoms and exposure history; a positive result alone does not confirm an allergy. This is general information, not medical advice.

Order online, choose a certified collection site in Puerto Rico, and review results through a secure portal. No referral is required, and orders are processed confidentially. With an island or territorial setting where arranging a specimen collection in advance is the norm, it pays to schedule your collection in advance.

Frequently asked questions

Does a positive result mean I am allergic to ethylene oxide?

Not necessarily. It means your blood has antibodies that can bind ethylene oxide. Only a clinician can decide if that explains your symptoms.

How long does it take to get results?

Most labs return results in 1 to 3 business days.

Do I need to fast before this test?

No. Fasting is not required for this blood test.

Can I take my allergy medicine before the test?

Ask your clinician. Some antihistamines can affect allergy testing, but do not stop any medicine without checking first.
