How to use OnTrak Test Cup ER
OnTrak Test Cup ER, an on-site integration drug testing device from Roche Diagnostics in Somerville, NJ, is very simple to use, so staff inservicing is minimal, notes Howard Freed, MD, chairman of the department of emergency medicine at District of Columbia General Hospital, in Washington, DC.
"The test is performed in the same plastic cup that the urinalysis is obtained in. A toxicology test is built into the cup, so no transfer of urine is necessary," he says. "It has controls for each test built right into the urine cup."
The Test Cup is simple to use. "There is no pipetting and no dipping of the card. After the specimen is collected, the cup is tilted for 10 seconds. In a couple minutes, you have the result and can read it on the side of the cup," says Stuart Bogema, PhD, a clinical toxicologist at Forensic Testing, a Clifton, VA-based research consulting firm that evaluated OnTrak Test Cup ER.
Once the urine sample is collected, the lid is secured and the sample is tilted forward for five to 10 seconds, allowing it to flow through a membrane to a sample reservoir in the cup. After the cup is righted and left undisturbed for a brief period, a distinct blue line in each drug’s "Test Valid" window indicates the results are ready. At that point, staff peel off the cover label to view the five results. Positive results are indicated by a white "plus" sign and negative results by a blue "minus" sign.
