A urine specimen is reported with a pH of 2.5. What does this result indicate under federal drug testing guidelines?
Answer: The specimen has been adulterated
A pH below 3.0 is outside the physiological range for human urine and indicates the specimen has been chemically adulterated.
What creatinine range identifies a dilute specimen in federal workplace drug testing?
Answer: Greater than or equal to 2 mg/dL and less than 20 mg/dL
A dilute specimen has a creatinine of at least 2 mg/dL but less than 20 mg/dL, indicating the specimen is physiologically produced but abnormally diluted.
Pyridinium chlorochromate (PCC), sold under commercial names like 'UrineLuck,' is best classified as which type of adulterant?
Answer: Oxidizing agent
PCC is a chromium-based oxidizing adulterant that destroys drug metabolites like THC in the specimen, making them undetectable.
What specific gravity range identifies a dilute urine specimen per federal guidelines?
Answer: Greater than 1.0010 and less than or equal to 1.0030
A dilute specimen has a specific gravity above 1.0010 (distinguishing it from substituted) but not exceeding 1.0030, reflecting abnormal dilution.
What is the minimum urine volume required to complete a federal workplace drug test, including the split specimen?
Answer: 30 mL
Federal guidelines require a minimum of 30 mL of urine—45 mL is the collection target—but 30 mL is the minimum needed to process both Bottle A (primary) and Bottle B (split).
A donor's specimen temperature reads 85°F (29°C), which is outside the acceptable range. What is the correct collector action?
Answer: Accept the specimen, document the temperature on the CCF, and consider a direct observed recollection
Per federal rules, an out-of-range temperature specimen is documented on the CCF and sent to the lab; the collector should also attempt to collect a second specimen under direct observation.
Under federal drug testing regulations, how long is a donor with 'shy bladder' allowed to attempt to produce a sufficient urine specimen?
Answer: Up to 3 hours
Federal regulations allow a donor with 'shy bladder' up to 3 hours to produce a sufficient specimen, during which they may drink up to 40 ounces of fluid.
