Testing the Validity of Pupillometer Technology Against Traditional Drug Screening Instruments

Volume 75 Number 3
December 2011

The author presents the results of a study to assess the validity of a pupillometer drug screening technology against two conventional measurements, urinalysis and oral swab, in screening probationers that were being monitored by a large urban court. He pays special attention to relative windows of detection, false-negative rates, and unconfirmed positives.
