Each kit has an identification number which is placed on the urine specimen, making it possible to obtain results anonymously. Directions for use and for obtaining and interpreting results are included in the kit. The designated laboratory is certified by the Substance Abuse and Mental Health Services Administration, the College of American Pathologists, and Health Care Financing Administration. The lab evaluates the urine sample for possible tampering and then analyzes it for drugs of abuse. The lab then does confirmation testing to minimize false positive reports and sends the results via computer to the company's results center.
Results are available one to three days after the lab receives the sample.
To obtain results, users call an 800 phone number and identify themselves by the identification number attached to the urine sample and instruction booklet. The center operates seven days a week during designated hours. A positive result indicates that the drugs tested for were present in sufficient quantity in the urine to be detected. FDA and the manufacturer recommend that test users who receive a positive test result, have questions about their results, or believe their results are inaccurate consult a physician for further evaluation. Although standard laboratory testing is highly accurate in detecting drugs of abuse in urine, certain medicines and, in rare cases, certain food may produce false positive test results.
