Lesson 6 Flashcards
It refers to the overall process of guaranteeing
quality patient care and it is the continual monitoring of the entire process test
ordering and specimen collection through
reporting and interpreting results.
QUALITY ASSURANCE
What are the process that was included in Quality Assurance?
Procedure manuals
Pre-analytical factors
Analytical factors
Post-analytical factors
It contains all the procedures performed in
the urinalysis section
PROCEDURE MANUAL
What are the included procedures done in Procedure Manual?
Principle or purpose of the test
Patient preparation
Specimen type and method of collection
Reagents,standards and control
Instrumentation calibration and maintenance
protocols and schedules
Procedure
Normal values
Limitations of the test
Reference
What are the Pre- Analytical Factors?
Test request
Patient preparation
Specimen collection and handling
It is the complete data of the patient
Test request
It is to give proper instructions to the
patients or relative of the patient
Patient preparation
It is where mostly mistakes happen
Specimen collection and handling
It is the processes that directly affect the testing of
the specimen
ANALYTICAL FACTORS
It refers to materials, procedures and
techniques that monitor the accuracy, precision and reliability of
a laboratory tests and it is also performed to ensure that acceptable
standards are met during the process of
patient testing.
Quality Control
It is used to verify accuracy and precision. Levy Jennings chart
Internal QC
It is the testing of unknown samples received
from outside agency and it provides unbiased validation of the
quality of patient test results.
External QC
What are the two type of Quality Control?
Internal Quality Control (Internal QC)
External Quality Control (External QC)
All reagents and reagent strip must be
properly labeled
Reagents
What are the way of proper labelling a reagent?
Date of preparation or opening
Purchase date
Appropriate safety information
refractometers, automated reagent
strip readers, automated microscopy
instruments, what are these?
Instruments
refrigerators, centrifuges, microscopes, water baths, what are these?
Equipment
This procedure is where detailed, concise testing instruction written
in a step by step manner
Testing procedure
What are the Analytical Factors?
Quality Control
Reagents
Instrumentation and Equipment
Testing Procedure
Person and Facilities
This is the processes that affect the reporting of results and correct interpretation of data.
POST ANALYTICAL FACTORS
What are the Post-Analytical Factors?
Reporting of Results
Interpretation of Results
Standardized reporting format, with reference ranges and written procedures should be available for reporting of critical values
Reporting of results
What are the Pre Analytical Quality Assurance Errors?
Patient misidentification
Wrong test ordered
Incorrect urine specimen type collected
Insufficient urine volume
Delayed transport of urine to the
laboratory
Incorrect storage or preservation of urine
What are the Analytical Quality Assurance Errors?
Sample misidentification
Erroneous instrument calibration
Reagent deterioration
Poor testing technique
Instrument malfunction
Interfering substances present Misinterpretation of quality control
What are the Post Analytical Quality Assurance Errors?
Patient misidentification
Poor handwriting
Poor quality of instrument printer Failure to send report Failure to call critical values
Inability to identify interfering substances
