Benzene, Occupational Exposure, Blood
Use
This test is used to evaluate occupational exposure to benzene, a volatile organic compound. Benzene is a common industrial chemical used in the production of plastics, resins, synthetic fibers, rubber lubricants, dyes, detergents, drugs, and pesticides. Benzene exposure is a recognized health hazard and is linked to acute myeloid leukemia (AML) and other blood disorders. Monitoring benzene levels in blood is crucial for workers in industries where benzene is present to ensure that their exposure levels are within safe limits.
Special Instructions
Not provided.
Limitations
The test has certain limitations regarding specimen handling and the timing of collection. Blood samples must be collected in sodium heparin tubes and filled completely to minimize benzene volatilization. Inadequate filling of tubes or incorrect collection timing may lead to inaccurate results. Hemolysis, lipemia, and icterus could interfere with the test results and are grounds for specimen rejection. Properly following collection instructions is essential for the validity of the results.
