LabX Diagnostic Systems is a CLIA-certified toxicology laboratory delivering definitive LC-MS/MS confirmation and screening — with fast turnaround and defensible, audit-ready results on every order.
Definitive LC-MS/MS confirmation
Presumptive (screening) testing tells you a drug class might be present. Definitive testing by liquid chromatography–tandem mass spectrometry (LC-MS/MS) confirms and quantifies the exact substance with the accuracy clinicians and payers expect. Our toxicology workflow is built around definitive confirmation ordered with clear clinical purpose — not blanket panels — so results hold up clinically and in an audit.
Ordered with clinical purpose
Toxicology is one of the most scrutinized areas of laboratory medicine. Testing is ordered by the treating provider based on their clinical judgment, with presumptive and definitive testing kept distinct. Our role is to deliver accurate, defensible results and audit-ready quality documentation that support your clinical decisions. For background on how medical necessity works, see our toxicology documentation guide and medical necessity overview.
Fast turnaround, full chain of custody
Most toxicology results are reported in 24–48 hours from receipt, with full chain-of-custody handling and audit-ready QC documentation on every specimen. When you call, a real person on our team picks up.
Reports built for clinical monitoring
Our reports are designed to make monitoring simple: a clear summary at the top for fast reading, therapeutic-range columns so you can read results in clinical context at a glance, and patient-history comparison so past and present results line up side by side. That makes it easier to track progress, confirm consistency, and adjust care plans — and reports can be customized to show the information you want, the way you want to read it.
Made for rehabilitation & monitoring settings
Toxicology at LabX is built for the realities of rehabilitation facilities, intensive outpatient programs (IOP), MAT and buprenorphine practices, and behavioral-health medication management — accurate, easy to administer, and light on staff burden. It pairs naturally with small-volume blood testing — collected by staff without a phlebotomist and able to detect substances within minutes and up to 72 hours — and with telehealth collection for patients who can't easily reach a lab.
Who we support
We partner with pain management, behavioral health, addiction medicine, and primary-care providers who need accurate, defensible drug testing to guide treatment and monitor medication adherence — turning assumptions into evidence. See how adherence monitoring improves outcomes.
