    Your One-Stop Provider for Medical Testing

    At Principle Laboratory, we work closely with medical providers and physicians to perform lab work for patients who require blood and urine testing. We support everything from basic chemistry and hematology to LCMS testing for toxicology, steroids, and hormones. We make it easier on you by allowing you to submit a variety of specimens for testing through a single channel rather than having to send your customers to multiple labs.

    We can assist you in giving your patients the impression that you are a “one-stop-shop” for all testing. Many smaller labs only offer toxicology performed on an analyzer. We are able to provide toxicology performed on HPLC-MS/MS (high-performance liquid chromatography with tandem mass spectrometry) as well as urine toxicology, oral fluid toxicology, wellness panels, blood chemistry and hematology testing, and more.
