What is this test?

The 1,2-Dichloroethane blood test measures the amount of this chemical in your serum or plasma. 1,2-Dichloroethane (also known as ethylene dichloride) is a colorless liquid chemical primarily used in industrial settings to make vinyl chloride, which is used to produce PVC plastics. It can also be used as a solvent and in certain chemical reactions.

Why might I need this test?

This test is most commonly ordered for workers in industries where 1,2-dichloroethane is used or produced, such as chemical manufacturing plants, PVC production facilities, or places where it's used as an industrial solvent. Your employer or occupational health department may require this test as part of workplace safety monitoring to ensure you haven't been exposed to harmful levels of this toxic chemical.

How is the test performed?

A healthcare professional will draw a small sample of blood from a vein in your arm using a needle. The blood sample will be sent to a laboratory for analysis. This is a simple blood test similar to routine blood work you might have during a regular check-up.

What do the results mean?

Results are typically reported as either detectable or not detectable (qualitative). If 1,2-dichloroethane is found in your blood, it indicates recent exposure to this chemical. Your healthcare provider will interpret the results in the context of your work environment and any symptoms you may be experiencing. It's important to discuss your results with a qualified healthcare professional who understands occupational health exposures.

Reference range

Not detected (reporting limit typically 0.1 ug/mL or lower)N/A

Specimen: serum

Avoid exposure to solvents and fuels for 24 hours prior to collection. Do not clean skin with alcohol or solvents before venipuncture. Collect in glass tubes only to prevent adsorption of volatile compounds to plastic.

Frequently asked questions

Is this a routine test?
No, this is not a routine test. It is specifically ordered for occupational health monitoring when there is a possibility of exposure to 1,2-dichloroethane in the workplace. Most people will never need this test.
How long does 1,2-Dichloroethane stay in your blood?
1,2-Dichloroethane is metabolized and eliminated from the body relatively quickly. It is typically detectable in blood for a short period after exposure (usually within days). This test indicates recent exposure rather than long-term cumulative exposure.
What should I do if my test shows exposure?
If the test shows detectable levels of 1,2-dichloroethane, you should discuss the results with your occupational health physician or healthcare provider. They will evaluate your work conditions, assess any symptoms, and recommend appropriate measures, which may include reviewing workplace safety procedures, using additional protective equipment, or temporarily removing you from the exposure source.
Can environmental exposure trigger this test?
Environmental exposure to 1,2-dichloroethane is rare for the general public. This chemical is primarily found in industrial settings. Most environmental exposures would involve very low levels that may not be detected by standard blood tests. If you are concerned about environmental exposure, discuss this with your healthcare provider.
