Benefits & Features

Ortho Clinical Diagnostics reduce errors icon

Get secure results

Increase confidence in results with unique sample processing capabilities, including single-use disposable tips, bubble and clot detection. Achieve fewer repeats, redraws, and dilutions than with traditional liquid systems. And avoid testing delays with self-monitoring that alerts operators to take prompt action.

Ortho Clinical Diagnostics meet demand icon

Meet increased demand with true workflow and testing consolidation

Generate up to 300 results per hour* with 40+ onboard chemistries. Deliver immediate results for STAT or routine testing and disease-focused panels with a wide, accessible onboard menu. Conduct random testing of serum, plasma, and urine at any time with MicroSlide technology and onboard dilution. And improve your lab’s productivity and turnaround time with primary tube sampling and optional positive sample identification (PSID).

*Depending on chemistry mix/panels run

Ortho Clinical Diagnostics reduce costs icon

Contain costs and save space

Lower your lab’s total costs with increased reportable result efficiency, fewer errors and interventions, and more effective staff utilization. With no plumbing, drains, vents, or deionized water, VITROS® technology delivers predictable financials and eliminates hidden costs, maintenance, and productivity issues associated with alternative systems. And the system’s small footprint requires less space and overhead expenses.

Ortho Clinical Diagnostics improve lab efficiency icon

Make the most of a limited staff

Train and cross-train operators quickly and easily with simple procedures that allow all members of your lab to access the system anytime, day or night. Reduce the number of hands-on tasks with automatic urine dilutions and on-demand serum dilutions. And rely on “load-and-go” reagent preparation, MicroSlide Technology, and extended calibration stability—so you can rededicate staff to value-added tasks.
