It ensures that blood samples are collected and processed appropriately, minimizing pre-analytical errors that may result in inaccurate or deceptive outcomes. This standardization enhances affected person security by lowering the chance of misdiagnosis or inappropriate remedy. Moreover, the system streamlines laboratory workflows, permitting technicians to rapidly establish the suitable tube for a particular take a look at, thereby bettering effectivity and lowering turnaround time for outcomes.
