Internal quality control management and troubleshooting errors

The February issue of Pathology in Practice will see publication of the ninth and final article in Dr Stephen MacDonald’s series on internal quality control (IQC). Here, he looks at the actions needed when processes deviate beyond expected variation, and the troubleshooting of IQC failure, which concludes the series on statistical quality control (SQC).
