Sampling should be done during or at the end of the work shift or week for industrial exposure contexts.
Limitations
The test is developed by LabCorp and its performance characteristics are determined internally. It has not been cleared or approved by the FDA, indicating that results might need further confirmation by additional testing or examination.
