Our Solution
VDx identified the gaps in standard validity testing for urine drug testing and developed modern technology to help laboratories close them. Detect the tactics designed to undermine the test before they undermine the decision.
When Standard Validity Testing Misses the Problem, Every Decision After It Is at Risk.
Drug-test data guides decisions in healthcare, treatment, courts, workplaces, and government programs. When a specimen is altered, diluted, or substituted and standard validity testing does not identify it, an apparent negative can hide the information those programs need to make an informed decision.
VDx brings new science to an issue the testing industry has allowed to stand still. Our goal is simple — make it harder for the subversion market to create misleading drug-testing data and give organizations stronger confidence in the results they receive.
New Innovative Products to Combat Subversion
Validity Diagnostics develops innovative technologies that detect subversion, reduce false negatives, support compliance, and help keep pharmaceutical drugs out of the wrong hands. The result is the Essentials Panel: six specimen validity tests that work together to show whether a sample can be trusted.

Runs In-House.
VDx reagents are configured for and validated on Beckman Coulter, Olympus AU, Thermo Fisher Indiko Plus, Carolina Liquid Chemistries CLC1600, and Siemens Atellica analyzers.

Sees What Standard Validity Testing Misses.
Modern specimen-integrity technology that identifies synthetic urine and other risks that standard validity testing can overlook.

The Essentials Panel
One complete panel that brings together all six VDx specimen-integrity tests, along with the calibrators and controls each test requires.
