What is this test?
The 1,4-Dioxane blood test detects whether this chemical is present in your bloodstream. 1,4-Dioxane is a clear liquid used in industrial processes, particularly as a solvent for dyes, oils, and greases. It is also found in some consumer products like cosmetics, detergents, and cleaning agents. The test is typically ordered for workers in industries where 1,4-Dioxane is used or produced, as part of occupational health monitoring programs.
How is the test performed?
A healthcare professional will draw a small sample of blood from a vein in your arm. The blood sample will be collected in a special tube and sent to a laboratory for analysis. You do not need to fast or prepare specially for this test. The blood sample will be tested to determine whether 1,4-Dioxane is present in your system.
What do the results mean?
A "negative" or "not detected" result means 1,4-Dioxane was not found in your blood at the time of testing. A "positive" or "detected" result indicates that you have been exposed to 1,4-Dioxane. Your healthcare provider or occupational health specialist will explain what this means for your specific situation and whether any follow-up actions are needed.
Reference range
Not DetectedN/A
No special preparation required. Avoid exposure to products containing 1,4-dioxane (certain cosmetics, detergents, adhesives) for 24-48 hours before sample collection if possible. Inform laboratory of any occupational or environmental exposure history.
