Phil the New Phlebotomy Tech is working in the outpatient lab. A patient has come in for a drug screening of urine. Phil places a tamper-proof urine collection cup in the bathroom designated for drug screening. After receiving the urine from the patient, Phil immediately examines the color of the urine, as well as noting the temperature. He notes his observations and initiates the chain of custody form. Why did Phil examine the color and temperature of the urine sample?
  1. Phil is a curious fellow.
  2. Phil is checking for evidence of tampering.
  3. Phil is checking for signs of dehydration.
  4. Phil is determining if drugs are present.
Explanation
Answer: B - Phil is checking for evidence of tampering. Many chemicals, fluids, and commercially available products can be used to skew drug-screening tests. Many urine collection devices intended for this type of testing are not only tamper proof, but made with a temperature sensitive strip to measure the temperature of the urine. Acceptable urine temperature is about 95-99 degrees. Urine should also be visually examined for color and turbidity. If Phil suspects tampering, he must request a second sampling. A second sample may require direct observation of the specimen collection process.
