Lesson 1 Flashcards
Introduction to LQMS (96 cards)
A degree to which an object or entity (process, product, or service) is excellent
Quality
T/F: Achieving a 99% level of quality means accepting a 1% error rate
True
Free from error or consistent with a standard or rule
Accurate
Trustworthy or of good quality
Reliable
Right time
Timely
How to achieve excellent performance in the laboratory?
Through QMS
coordinated activities to direct and control a organization with regard to quality (ISO, CLSI)
Quality Management System
All aspects (equipment, workflow, etc.) of the lab operation need to be addressed to assure quality; this constitutes a quality management system
Quality Management System
What are the different phases of a QMS?
Pre-examination phase
Examination phase
Post-examination phase
- patient preparation & sample collection
- personnel competency & test evaluation
- sample receipt & accessioning
- sample transport
Pre-examination phase
- centrifuge and aliquoting
- making sure sample is free from hemolysis
- serum/ plasma
Pre-examination phase
-FBS/ Lipid profile
- clear and quality instructions to patient
- verbal / written instructions
- ask for patient’s last meal (underfast/ overfast)
Pre-examination phase
uses reagent that resembles human sample
Quality control testing (Examination phase)
Control samples: Normal and Abnormal
Clinical Chemistry
Control samples: Low, Normal, High
Hematology
T/F: Quality control testing can be done daily
True
T/F: If values are outliers, reagents may be expire already
True
T/F: If values are within range, it is not safe
False; it is safe!
- reporting
- record keeping
Post-examination phase
T/F: Manual record keeping are prone to errors and used by primary laboratories
False; it is used by secondary laboratories
Quality control can be the basis of the result explanation
Laboratory Information System (LIS)
This is when previous test results are compared to recent one
Delta checking
Path of workflow
Patient -> Test selection -> Sample collection -> Sample transport -> Lab analysis examination phase -> Report creation -> Report transport
What influences laboratory tests?
- reagents and equipments
- communications
- process management
- lab environment
- knowledgeable staff
- competent staff
- quality control
- occurrence management
- record keeping
