  1. When collecting a urine specimen for a federal workplace drug test, what is the required minimum specimen volume?

    Answer: 30 mL

    Federal DOT guidelines require a minimum of 30 mL of urine for a split specimen drug test.

  2. A donor presents for a urine drug screen and cannot produce a specimen after 3 hours. What is the correct collector action?

    Answer: Document a 'shy bladder' and notify the MRO/employer

    After 3 hours without a specimen, the collector must document the 'shy bladder' condition and notify the Medical Review Officer and/or employer per DOT regulations.

  3. Which action is required BEFORE a donor enters the restroom to provide a urine specimen?

    Answer: Instruct the donor to leave outerwear and bag outside

    The donor must leave outer garments, bags, briefcases, and purses outside the restroom to minimize the opportunity for specimen adulteration or substitution.

  4. What is the correct temperature range for a valid urine specimen immediately after collection?

    Answer: 90–100°F (32–38°C)

    DOT regulations specify that a fresh urine specimen temperature must fall within 90–100°F (32–38°C) as measured within 4 minutes of collection.

  5. If a split specimen urine collection produces 30 mL total, how should volume be distributed between the primary (A) and split (B) vials?

    Answer: 20 mL in A, 10 mL in B

    DOT protocol requires at least 15 mL in the primary (A) vial and at least 8 mL in the split (B) vial; the standard split is roughly 20 mL in A and 10 mL in B.

  6. During a monitored collection, which situation requires the collector to conduct a direct-observation collection?

    Answer: Collector suspects a prosthetic device or specimen substitution device

    If the collector or a team member observes or has reason to believe a donor is using a substitution device, a direct-observation collection must be performed.

  7. Which substance, if found in a urine specimen, would indicate possible adulteration with bleach?

    Answer: Abnormally high pH and presence of oxidants

    Bleach is an oxidizing agent; its presence raises urine pH significantly and tests positive for oxidants on validity testing strips.
