The price is primarily driven by throughput (tests per hour) and the level of automation. Fully automated systems that handle capping, sampling, and dilution are significantly more expensive than semi-automated models. Key technical factors include the number of measurement channels (e.g., 2, 4, or 8 channels), the detection method (optical vs. magnetic bead), and the reagent cooling capacity. Systems with integrated barcode scanners and LIS (Laboratory Information System) bi-directional connectivity also command a premium.
