Quality issues | Quality issues can be examined in a number of different ways. | ||
Finding a problem: | |||
*Root cause analysis. | |||
Anticipating problems: | |||
*Failure mode and effects analysis (FMEA). | |||

Pathology errors happen any time from when the lab gets the specimen until after the report is issued. | |||

A common way to break down error analysis is: | |||
{{familytree/start}} | |||
{{familytree | | | | | | | | | A01 | | | | | |A01=Errors in pathology}} | |||
{{familytree | | | | |,|-|-|-|-|+|-|-|-|-|.| |}} | |||
{{familytree | | | | B01 | | | B02 | | | B03|B01=Pre-analytical errors|B02=Analytical errors|B03=Post-analytical errors }} | |||
{{familytree/end}} | |||

The implication of irregularies in the different classes are different. Problems in ''Class II'' tests are potentially more severe, as there is no internal control. | The implication of irregularies in the different classes are different.
