Abstract
The present invention relates to a method and a kit for verifying the source and completeness of urine samples when collected for testing for the presence of drugs of abuse. The method involves observing an individual consume (1) a quantity of a first chemical marker reagent capable of confirming upon chemical analysis the completeness of the urine sample and (2) a quantity of a second chemical marker reagent capable of confirming upon analysis the accuracy of the source of the urine sample. The urine subsequently collected is analyzed by known analytical techniques.
Claims6
A method for verifying the source and completeness of a urine sample comprising:
- (a) observing an individual consume a quantity of a first chemical marker quantitatively excreted in urine, said first chemical marker capable of confirming upon chemical analysis the completeness of a urine sample;
- (b) observing the individual consume a quantity of a second chemical marker secretable in measurable amounts in urine, said second chemical marker capable of confirming upon chemical analysis the accuracy of the source of a urine sample;
- (c) requiring the individual to collect a urine sample within a period of time from said consumption sufficient to allow requisite quantities of the first and second chemical markers to be secreted in the urine;
- (d) documenting the time, quantity and identity of the chemical markers consumed as well as the identity of the individual;
- (e) subsequently chemically analyzing the urine sample by known analytical techniques to determine the quantities of the first and second chemical markers therein and from the determined quantities verifying the source and completeness of the urine sample in relation to the information documented.
A kit for use in verifying the source and completeness of urine samples comprising:
- (a) a container for collecting a urine sample;
- (b) a fluid containing a quantity of a first chemical marker quantitatively excreted in urine, said first chemical marker capable of confirming upon chemical analysis the completeness of a urine sample, and a quantity of a second chemical marker secretable in measurable amounts in urine, said second chemical marker capable of confirming upon chemical analysis the accuracy of the source of a urine sample.
