Quality issues are examined a number of different ways, e.g. root cause analysis, failure mode and effects analysis (FMEA).
Quality issues can be examined in a number of different ways.


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


====Failure-potential analysis====

*Failure mode and effects analysis (FMEA).
#Identify potential individual failures.
#Identify the consequences of those failures.
#Identify how the individual failures can arise.
#Identify the corrective action.

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

**If it is a ''[[critical diagnosis]]'' contact the most-responsible physician immediately... if they are unreachable call the physician on-call for the most-responsible physician... if the patient is out-of-town you may have to coordinate with the local emergency department.

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.
