§40.61
No one is ever permitted to obtain a urine specimen for DOT testing purposes from an unconscious individual, whether by catheterization or any other means.
No one is permitted to catheterize a conscious employee for the purpose of collecting urine for a DOT drug test.
However, if a person has been catheterized for medical purposes (e.g., a conscious, hospitalized patient in a post-accident test situation), it is permissible to use urine collected by this means for DOT testing purposes. All necessary documentation for a DOT collection must be provided (e.g., the CCF).
In addition, an employee who normally voids through self-catheterization is required to provide a specimen in that manner.
