We excel in customer service and exceeding the needs of our clients, community and health system.

Our liquid chromatography interfaced to tandem mass spectrometry (LC/MS/MS) is used to deliver an unparalleled level of accurate and extensive data analysis.

Our medication monitoring system provides valuable information that increases the safety of prescribing medications by identifying the potential for overdose and drug interactions.

LC/MS/MS is the new gold standard of analytical toxicology and is an indispensable tool.
