What is a characteristic of closed systems in laboratory testing?

Closed systems in laboratory testing are designed to be highly automated, which significantly reduces the need for manual intervention and user interaction. This characteristic allows for streamlined processes, minimizing the potential for human error and increasing the reliability and consistency of test results. Closed systems typically involve pre-defined protocols and standardized reagents, which contribute to their ease of use and facilitate high-throughput testing.

The emphasis on automation in closed systems enhances efficiency and ensures that processes are not only faster but also reproducible, as each test follows the same set procedure without variation. This allows laboratories to handle larger volumes of samples while maintaining a high level of quality control.

Other characteristics of closed systems, such as limited flexibility and difficulty in modification, further support their operational structure, focusing on reliability over adaptability. Thus, the automation in closed systems sets them apart from more manual and flexible laboratory setups, aligning perfectly with the definition provided in this context.
