Our Solution
VDx identified the gaps in standard validity 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 has developed innovative technologies that detect subversion, reduce false negatives, help increase compliance, and limit the diversion of pharmaceutical drugs into the wrong hands. The result is the Essentials Panel: six specimen validity tests that work together.

Runs In-House.
VDx reagents are currently implemented 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 designed to identify synthetic urine and other risks standard validity testing may miss.

The Essentials Panel
All six VDx specimen-integrity tests, together with the calibrators and controls each requires, brought together in one complete panel.
