Quality Control

Quality control refers to the process of detecting analytical errors within the laboratory to ensure both the reliability
and accuracy of test results. Poor performance can result in misdiagnosis, delayed treatment, increased costs and
may even be potentially life threatening for the patient. Without good quality control, how can you be confident the
results you provide are accurate?

‘The purpose of quality control is to monitor the
analytical quality of a procedure, detect changes
and eliminate reporting results with medically
important errors’ 1
