# Internal & External Quality Control in the Clinical Lab Course

Medical Testing Laboratory should design quality control to detect, reduce, and correct deficiencies in a laboratory’s examination process. The laboratory management should make sure that the quality control material must be processed as per the quality management plan for each department, then do the daily, weekly and monthly evaluation with combine with the External Quality Control.

Medical Testing Laboratory should design quality control to detect, reduce, and correct deficiencies in a laboratory’s examination process. The laboratory management should make sure that the quality control material must be processed as per the quality management plan for each department, then do the daily, weekly and monthly evaluation with combine with the External Quality Control.

External Quality Assessment is used to calculate accuracy. In the discipline of anatomic pathology, nonstatistical tools are used to assess the performance.
