Why This Test Is Done

Your healthcare provider may order this test if you have symptoms like numbness, tingling, or nerve damage, or if you work in industries where vinyl chloride is used, such as plastics manufacturing. It may also be part of routine monitoring for individuals with known exposure.

What to Expect Before the Test

No special preparation is usually needed. You may be asked to fast for 8–12 hours before the test if blood is drawn from a vein, but this depends on the lab’s protocol. Bring any medications or supplements you’re taking.

How the Test Is Performed

A healthcare professional will draw blood from a vein in your arm using a small needle. You may feel a slight pinch, but it usually doesn’t cause discomfort. The blood sample is then sent to a lab for analysis.

What the Results Mean

Higher-than-normal levels may indicate recent exposure to vinyl chloride, which can lead to health risks over time. Your results will be compared to clinical guidelines rather than a single reference range.

Reference range

Adult: 98-107 mmol/LN/A

Specimen: serum

No special preparation required. Stay well hydrated.
