Study Notes
Clinical Chemistry I - Week 08: Quality Management
- Course code: 0202304
- Instructor: Mohammad Qabajah
- Email: [email protected]
Objectives
- Describe the quality control system and methods for validating lab results.
- Describe lab testing processes and potential errors.
- Understand pre-analytical, analytical, and post-analytical variables and their impact on lab results.
- Detail how each pre-analytical, analytical, and post-analytical variable is controlled.
Total Quality Management (TQM)
- Encompasses managing the entire clinical lab for quality.
- Includes controlling pre-analytical, analytical, and post-analytical variables.
- Utilizes external quality assessment and proficiency testing programs.
- Early detection of issues helps prevent consequences.
Implementing TQM
- Quality Planning (PDCA - Plan Do Check Act)
- Quality Laboratory processes (QLP)
- Quality Control (QC)
- Statistical and non-statistical procedures (linearity, reagent/standard checks, temperature monitoring)
- Quality Assessment (QA)
- Turnaround time, specimen & patient ID, test utility
Control of Pre-analytical Variables
- Patient Identification:
- Correct patient and specimen identification.
- At least two identifiers are needed.
- Turnaround Time (TAT):
- Time from specimen submission to analysis.
- Time to report results.
- Define specific TAT for each lab test and monitor it.
- Specimen Collection:
- Proper collection procedures (preservative & containers).
- Specimen Separation/Distribution:
- Use centrifuges & appropriate containers for aliquots.
- Specimen Transport:
- Proper temperature control (cooled, frozen, protected from light).
- Laboratory Log/Specimen Request:
- Data entry accuracy is critical (electronic logs preferred.)
- Patient name, ID, matching specimen, adequate volume, all tests requested, and rejection reasons.
- Patient Preparation:
- Patient factors can impact test results (food, alcohol, drugs, smoking, exercise, stress, sleep.)
- Define clear patient preparation instructions and specimen acquisition protocols.
Non-controllable Variables
- Biological Influences:
- Age (newborn, child, adult, elderly)
- Sex
- Environmental Factors:
- Altitude
- Ambient temperature
- Geographic location
- Seasonal influences
- Underlying Medical Conditions:
- Obesity
- Blindness
- Pregnancy
- Fever
- Shock and trauma
