Abstract
The invention described herein includes a method of testing an analyte such as urine to determine whether the analyte contains specific substances such as drugs of abuse. An on-site screening test provides a preliminary test result either by visual or machine analysis of a screening test device, and the result and user data are entered on a provided form. An electronic image of the form is sent to a central data location, where it is received and the data on the form is recognized by machine and stored. If the on-site screening test provided a nonnegative result a sample is sent to a laboratory for further testing, and if the test provides only negative results no further testing is done. The testing laboratory performs further testing for verification of nonnegative screening test results, and all data is collected at the central data location. Results are then reported to the client or whoever the client designates to receive test results.
