exam 1 Flashcards
QM in the lab
framework for managing and monitoring activities to address quality standards and achieve organizational goals
Quality assurance
ensuring that plans, policies and procedures across the entire path of specimen workflow are followed.
- assessing the info gathered during QC activities & identifying & eliminating problems
are quality assurance and quality assessment the same thing?
yes
Quality Control
focuses on analytical, usually monitoring and recording the daily performance of lab equipment, as well monitoring testing reagent lot #s and expiry dates
internal controls are used within labs to…
ensure quality testing results
statistical QC
involves running specimens controls with known values
purpose is to detect error in the procedure by comparing control results to expected values
non statistical QC
does not monitor actual production of test results, but it supports the ability to ensure our test results are valid
(documenting daily temperatures)
trouble shooting:
F- figure out what’s going on
I- isolate the cause
R- resolve the problem
E- evaluate the solution
D- document all steps and outcomes
specimen integrity
before either specimen POC testing or specimen loading on an instrument, it is imperative to ensure sample integrity
hemolyzed
damaging of intact RBCs
fluid portion serum/plasma will appear clear red due to RBCs been lysed and the release of hemoglobin into fluid oortion
icteric
specimens can be identified by abnormal yellow-brown colour of the specimens plasma/serum
due to an increase of bilirubin the blood
lipemic
both serum/plasma will appear foggy and have a white hue due to presence of fats and lipids suspended in the fluid portion of blood
specimen collection is part of which workflow in the lab
pre analytical
preparing QC material is a part of which workflow in the lab
analytical
specimen storage in walk in fridges is part of which workflow in the lab
post analytical
when a lab profession prepares and runs QC material on a set schedule, what i type of QC are they performing
internal statistical QC
what range on the standard bell curve is selected most often for the limit of control ranges in the clinical lab
+/- 2 SD
in the acronym FIRED used for troubleshooting, what does the E stand for
evaluate
which workflow do most lab errors happen
pre analytical
asking patient to identify themself is what workflow
pre analytical
