SAP Drug & Alcohol Testing Procedures 3

Question 1

What is the 'shy bladder' protocol in DOT urine drug testing?

Accepted Answer

The employee is given up to 3 hours to produce a sufficient specimen; failure without a medical explanation is treated as a refusal

Answer

Per 49 CFR Part 40.193, the employee has up to 3 hours (with up to 40 oz of fluid) to provide the specimen; if unsuccessful without a verified medical reason, it is a refusal to test.

Question 2

Why is a bluing agent added to the toilet water in a DOT urine specimen collection restroom?

Accepted Answer

To prevent the donor from diluting or adulterating the specimen with toilet water

Answer

The blue dye makes toilet water visually distinct from urine, so any tampering with toilet water would be immediately apparent in the specimen.

Question 3

Under DOT regulations, who has the right to request testing of the split specimen (Bottle B) following a confirmed positive laboratory result?

Accepted Answer

The employee (donor)

Answer

49 CFR Part 40.171 gives the employee the right to request a split specimen retest within 72 hours of MRO notification of the confirmed positive result.

Question 4

What is the minimum volume required in Bottle B (the split specimen) of a DOT urine drug test collection?

Accepted Answer

15 mL

Answer

49 CFR Part 40.73 requires Bottle B to contain at least 15 mL of urine to allow a valid confirmation retest if the employee requests one.

Question 5

If a DOT laboratory cannot perform a valid analysis on the primary specimen (Bottle A), what is the correct procedure?

Accepted Answer

The laboratory opens Bottle B and uses it as the primary specimen for testing

Answer

Under 49 CFR Part 40.83, when Bottle A is untestable, the laboratory is authorized to open the split specimen (Bottle B) and use it as the primary specimen.
