Industrial medicine (organic solvents, lead) related test

The main purpose of industrial medicine-related tests is to periodically check the level of organic solvents and lead in the body of those who work with organic solvents and lead, so the evaluation of the results is not intended to differentiate between normal and abnormal conditions, but requires a comprehensive judgment that takes into account the work environment.
In addition, each regulation on prevention of poisoning based on the Industrial Safety and Health Law stipulates that a report on the results of each medical examination must be submitted to the director of the relevant Labour Standards Inspection Office.

  • *1 Since November 2014, styrene, trichloroethylene, and tetrachloroethylene have been positioned from the Organic Solvent Poisoning Prevention Regulations to be subject to The Specified Chemical Substance Hazard Prevention Regulations.
    Although distribution category reporting to the Labor Standards Inspection Office is not required for health examinations for specified chemical substances, this information is provided as an indicator to monitor the progress of the examination results.
  • *2 The measurement value is the sum of mandelic acid and phenylglyoxylate acid.

Specimen Handling Instructions
