DDL developed and utilizes a specimen collection procedure, which essentially precludes adulteration and substitution of urine samples. A digital temperature check, which allows a narrow acceptable range of temperatures, based on time and volume of the specimen certifies the integrity of the sample. This procedure has been found to be more effective than "witnessed" collections and is far superior to the procedure allowed by the federal (SAMSHA) regulations.

The DDL procedure was developed and tested through the collection of thousands of specimens including specimens, which were purposefully adulterated with so called commercially available masking agents, or specimens that were purposefully substituted.

Federal regulations allow the use of a temperature range of 90 to 100 degrees, which does not preclude adulteration or substitution. In addition many collection facilities use "temp strip" thermometers which are attached to the collection container, which is likewise not recommended and in fact provide the facility to the drug user to successfully manipulate the temperature of the specimen.

DDL's unique collection procedure has been peer reviewed by independent Forensic Toxicologists. All forensic drug testing collections are done with full chain-of-custody including the collection of a referee specimen which is stored frozen and unopened for 1 year if testing is reported "positive" for any drug.

Individuals who provide specimens, which do not pass the certification process, are given another opportunity to provide a certifiable sample. They are allowed to drink water, but are asked to remain in the waiting room until they can provide another specimen. If the subject refuses to provide another specimen or provides another specimen that fails the certification, the collection is considered a failed collection attempt and a report is issued with that statement.

DDL's collection protocol is strict but is not a problem with the vast majority of individuals that provide fresh samples. Occasionally, a person may not follow directions and may fail to produce the specimen in a sufficient time to enable certification. In these rare cases, the subject may provide a second sample, which will then be certified.

Individuals who fail the certification due to adulteration and/or substitution will either provide an acceptable sample in which case the testing will provide the information or will not cooperate which will likely result in a 'failed collection attempt'.
