Which of the following is NOT considered LIS hardware?

The correct answer is identified as clinical guidelines, as they do not fall under the category of hardware used in a Laboratory Information System (LIS). Rather, clinical guidelines are established protocols or recommendations that assist healthcare professionals in making decisions about patient care, ensuring effective treatment protocols and enhancing patient outcomes. These are primarily procedural and cognitive in nature, rather than physical components that interact within the LIS.

In contrast, barcode scanners, networking equipment, and computers are all tangible devices that facilitate data entry, storage, and transmission of laboratory information. Barcode scanners allow for accurate data capture from specimens, networking equipment enables communication between devices and systems, and computers serve as the primary workstations for the laboratory staff to access and manage the LIS. Understanding the distinction between hardware and procedural elements is critical for effective laboratory management and the practical use of technology in clinical settings.
