MRO Drug Testing Procedures 2 — Questions and Answers
Question 1: What is the minimum urine specimen volume required for a DOT federal workplace drug test?
- 30 mL (Correct answer)
- 45 mL
- 60 mL
- 90 mL
Correct answer: 30 mL
DOT regulations require a minimum of 30 mL of urine to complete a federal workplace drug test.
Question 2: Which document is used to document chain of custody for a federal workplace urine drug test?
- DEA Form 222
- Federal Drug Testing Custody and Control Form (CCF) (Correct answer)
- SAMHSA-1 Form
- MRO Verification Report
Correct answer: Federal Drug Testing Custody and Control Form (CCF)
The Federal CCF is the required form for maintaining chain of custody in all DOT-mandated urine drug tests.
Question 3: If a donor cannot provide an adequate specimen on the first attempt, how long must the collector allow the donor to try again?
- 15 minutes
- Up to 3 hours (Correct answer)
- 30 minutes
- Until the next scheduled workday
Correct answer: Up to 3 hours
Under DOT rules, the collector must allow the donor up to 3 hours to provide a sufficient specimen before documenting a refusal.
Question 4: When a direct observation collection is required, who may observe the donor provide the specimen?
- Any trained collector regardless of gender
- A collector of the same gender as the donor (Correct answer)
- A licensed medical professional only
- The donor's direct supervisor
Correct answer: A collector of the same gender as the donor
DOT regulations require that the observer during a direct observation collection must be the same gender as the donor.
Question 5: What is the acceptable temperature range for a urine specimen when presented to the collector?
- 90–100°F (32–38°C) (Correct answer)
- 95–105°F (35–41°C)
- 98–106°F (37–41°C)
- 86–98°F (30–37°C)
Correct answer: 90–100°F (32–38°C)
A valid specimen must read between 90°F and 100°F on the temperature strip within 4 minutes of collection.
Question 6: What action must a collector take if a specimen temperature falls outside the acceptable range?
- Discard the specimen and end the collection
- Document the discrepancy on the CCF and collect a second specimen under direct observation (Correct answer)
- Accept the specimen and note the temperature discrepancy only
- Immediately report the issue to the MRO before proceeding
Correct answer: Document the discrepancy on the CCF and collect a second specimen under direct observation
An out-of-range temperature triggers a CCF notation and a second collection under direct observation to detect possible substitution.
Question 7: At what point during the collection process must the collector seal the specimen bottles?
- In a private collection area away from the donor
- In the presence of the donor (Correct answer)
- After the donor has left the collection facility
- Only when witnessed by the MRO
Correct answer: In the presence of the donor
Sealing the specimen bottles in the donor's presence maintains chain of custody integrity and prevents tampering allegations.
