Analysis of methods for IQC
Analysis of the problems surrounding the traditional methods used for IQC: manufacturer-assigned range, Spreadsheets, LIS/ Equipment, with a comparison of the modern solution System for IQC.
This guide, presented below, will help you understand, criticize what you use and choose the one with efficient resources to improve the quality of analysis processes, facilitate decision-making and increase confidence in the results you deliver to patients.
It contains the way to overcome restrictions of traditional methods and better evaluate the analytical performance of the Clinical Analysis Laboratory.
The new regulation RDC 978/2025 ANVISA makes the use of traditional methods for Internal Quality Control unfeasible, requiring an appropriate tool to meet the most rigorous control criteria. QualiChart is an ideal system as a modern method for IQC, fully meeting DRC requirements, reducing the time spent on the daily control routine by 85% and ensuring efficiency, compliance and reliability in laboratory results.
Data Stream
Manufacturer's Stated Range
- ✓Presents values as a reference for starting the control
- ✗References are only for initial analyzes
Spreadsheets
- ✗Manual data collection and entry
- ✗More time taken to execute
LIS / Equipment
- ✓Data provided by equipment
- ✗Information presented separately
System for IQC
- ✔Data from all equipment in one place
Analytical calculations
Manufacturer's Stated Range
- ✗Does not apply multiple rules
- ✗Does not calculate Mean, Standard Deviation and Coefficient of Variation
Spreadsheets
- ✓Enables control chart plotting
- ✗There is no possibility of handling more than one control level
LIS / Equipment
- ✓Automatically plots the graph
- ✗Some do not apply Multiple Rules
System for IQC
- ✔Multiple Rules Automatic Test
- ✔Calculation of Mean, Standard Deviation and Coefficient of Variation
- ✔Automatic Levey-Jennings Plot
Time and processes
Manufacturer's Stated Range
- ✗Many processes involved
- ✗More time taken to execute
Spreadsheets
- ✓Speeds up time spent on execution
- ✗Large amount of data to process
- ✗Typos
LIS / Equipment
- ✓Information presented more objectively
- ✗Little standardization of the analytical environment
System for IQC
- ✔Process standardization
- ✔Fast and automatic execution
Data interpretation
Manufacturer's Stated Range
- ✗Does not find trends and other changes
- ✗Does not allow analysis of the Levey-Jennings graph
Spreadsheets
- ✗Requires understanding from technicians at the bench to interpret data
LIS / Equipment
- ✗Manual joining of data from each device
- ✗Requires understanding from technicians at the bench to interpret data
System for IQC
- ✔Launches error alerts
- ✔Classifies the type of error
- ✔Searches for the root cause to identify a solution
Review
Manufacturer's Stated Range
- ✗You must know the steps for a more assertive critical analysis
- ✗Too much information to deal with manually
Spreadsheets
- ✗Depends on technical knowledge for evaluation
- ✗Does not allow a complete view of the control for evaluation
LIS / Equipment
- ✗Does not perform a comparative analysis of the laboratory impression, measured by the Coefficient of Variation
System for IQC
- ✔Automatically performs critical analysis
- ✔Launches alerts
- ✔Classifies the type of error
- ✔Searches for the root cause to identify a solution
Error handling
Manufacturer's Stated Range
- ✗Takes a long time to evaluate the type of error
- ✗Definition of corrective action made difficult
Spreadsheets
- ✗Bench experience required to identify root causes and define corrective actions
LIS / Equipment
- ✗Does not display alerts for nonconformities
- ✗Makes it difficult to evaluate errors and make decisions
System for IQC
- ✔Indicates nonconformity
- ✔Presents possible causes of variation in results
- ✔Defines remediation actions for recurrence control
Control Management
Manufacturer's Stated Range
- ✗Lack of personnel to carry out the process
- ✗Difficulty passing daily control for all analytes
Spreadsheets
- ✗Does not allow complete control analysis
- ✗Incomplete and delayed evaluation
LIS / Equipment
- ✗Limited view of the analytical environment
- ✗Difficulty maintaining control stability
System for IQC
- ✔Monitoring in one place of routine data from all monitored equipment and units
Information Record
Manufacturer's Stated Range
- ✗Lack of effective registration
- ✗Makes it difficult to consult significant information about occurrences in the control
Spreadsheets
- ✗Very complex to handle the numerous quantitative tests, with records and reports
LIS / Equipment
- ✗Demands daily logging actions for numerous analytes, analysis logging and reports
System for IQC
- ✔Complete history of each analyte and non-conforming occurrences, rules violated and corrective measures, for guidance in case of error recurrences
Evaluate your current method
Your current method performs internal control in full form?
Answer with YES or NO to assess whether the method you use today meets IQC requirements:
- Does your current method automatically centralize control data from all equipment into a single system?
- Does your current method apply Westgard Multiple Rules automatically and alert you to control errors?
- Does your current method automatically identify the type of error and present possible causes and corrective actions?
- Can you complete the IQC routine for all lab analytes in less than 30 minutes per day?
- Does your current method record the complete history of occurrences and generate IQC reports ready for Health Surveillance?
0 NOT answered
If you answered NO to three or more of these questions, your current method is not fully performing internal quality control.
