The Stanbio Chemistry Procalcitonin (PCT) LiquiColor assay from EKF Diagnostics has been FDA-cleared and validated for use on Beckman Coulter AU 480, 680, and 5800 clinical chemistry analyzers. A user-defined application (UDA) is available for running this 10-minute test for bacterial infection and sepsis on these Beckman AU analyzers. PCT is a marker widely accepted for use in conjunction with other tests to quickly identify sepsis and monitor progression/severity over time. Designed to be used on an open channel of most main-brand clinical chemistry analyzers, the availability of the User Defined Application (UDA) on Beckman AU analyzers further increases the LiquiColor PCT assay’s breadth of application.
