CPC Donor Identification & Verification Flashcards

What is the significance of a shy bladder situation during a federally regulated drug test?

Answer: The donor is unable to provide a sufficient specimen volume and must follow a specific protocol

Shy bladder means the donor cannot provide the required 45 mL specimen, triggering a monitored waiting period of up to three hours under 49 CFR Part 40.

During the shy bladder waiting period, what restriction applies to the donor?

Answer: The donor must remain at or near the collection site

The donor must stay at or near the collection site during the shy bladder waiting period to prevent unauthorized departure or specimen substitution.

How much fluid may a collector offer a donor experiencing shy bladder during the three-hour waiting period?

Answer: Up to 40 ounces of water

Under DOT Part 40, the collector may offer the donor up to 40 ounces of water during the three-hour shy bladder waiting period.

If a donor is still unable to provide a specimen after the three-hour shy bladder period, what must the collector do?

Answer: Discontinue the collection and document it as an incomplete collection, notifying the DER

After three hours without a sufficient specimen, the collector must stop, document the situation, and notify the DER who will arrange a physician evaluation.

What is the minimum specimen volume required for a standard urine drug test under DOT regulations?

Answer: 45 mL

DOT Part 40 requires a minimum of 45 mL of urine for a valid split specimen collection (30 mL primary, 15 mL split).

Which action by the collector helps confirm that a donor provided a fresh urine specimen during collection?

Answer: Checking that the specimen temperature is between 90°F and 100°F within four minutes of collection

A temperature reading of 90–100°F within four minutes confirms that the specimen is freshly voided and not substituted.
