What’s internal quality control (IQC)?
Training and consultancy for testing laboratories. What’s Internal Quality Control (IQC)? A professionally run test laboratory must have a set of internal quality control or check (IQC) procedures in place. Regrettably I have noticed that many accredited chemical laboratories do not institute such IQC system in their routine works.
What does iqcp stand for?
Individualized Quality Control Plan (IQCP) The Clinical Laboratory Improvement Amendments of 1988 (CLIA) regulations require a laboratory to have quality control (QC) procedures to monitor the accuracy and precision of the complete testing process.
What is the CLIA iqcp?
The CLIA Individualized Quality Control Plan (IQCP) is a recently developed, risk-based, objective approach to performing quality control testing. The IQCP is based on assessment of the unique laboratory testing in use, patient populations, and other aspects (for example, internal quality checks built into new instruments).
What is the difference between IQC and EQA?
While IQC controls the precision of investigations, EQA should be providing an assessment of their accuracy (lack of bias) with respect to other test sites. This is done periodically and retrospectively, hence use of the term 'assessment' rather than 'control'.
What is Eqc in laboratory?
EQC allows a laboratory to reduce external QC on the assumption that a manufacturer's internal QC (electronic measures, physical checks, internal controls) are effective in identifying any problems with the testing process.
What is the difference between IQA and Iqc?
Quality assurance is a set of activities intended to establish confidence that quality requirements will be met. QA is one part of quality management. Quality control is a set of activities intended to ensure that quality requirements are actually being met.
What is IQC?
Internal quality control (IQC) ensures that factors determining the magnitude of uncertainty do not change during the routine use of an analytical method over long periods of time.
What is IQC material?
What is IQC? IQC is used to monitor analytical activities; ensuring that the laboratory observes and monitors an effective and sufficient control over instrument and reagent performance.
What is quality Eqc?
The rationale behind EQC is that if the test system is operating within specifications and the manufacturer reliably delivers consistent and uniform quality products, a simple electronic check will assure that the entire testing process is in control.
What is the role of EQA?
An EQA's role is to review the processes of assessment and internal quality assurance within an approved centre. An EQA must ensure approved centre staff members are making assessment judgements that are consistent with the qualification learning outcomes and assessment criteria.
Who performs EQA?
External Quality Assurance (EQA) is the process of ensuring that assessment and IQA activities have been conducted in a consistent, safe and fair manner. External Quality Assurance is carried out by the Quality Assurer of the Awarding Body. This must be an Awarding Body that is registered with the Training Provider.
Is Iqa can be done after EQA?
External quality assurance (EQA) seeks to ensure that assessment and internal quality assurance activities (IQA) have been conducted in a consistent, safe and fair manner. The process must take place on behalf of an awarding organisation (AO) for each approved centre which offers their qualifications.

Why is internal QC important?
In contrast to external quality assurance, “Internal QC” or “intra-laboratory QC” is essential for detecting problems that arise during the routine operation of laboratory methods. Those problems are caused by the instability of the method, i.e., changes in performance compared to what was observed earlier. In essence, internal QC compares laboratory performance to itself over time, assuming that the performance observed earlier represents correct or accurate test results. This assumption should be validated initially by method validation experiments and must be validated on a continuing basis by “external quality assessment programs.”
What is external quality assessment?
In an external quality assessment program, a group of laboratories analyze the same specimens (usually the same control materials, exact same lot numbers) and submit their results to a central facility where the data are examined for outliers, and means and SDs are calculated to characterize the performance of the group of laboratories, and reports are generated to compare the performance of an individual laboratory to the peer group and sometimes to target values established by reference methods or reference laboratories.
Why do laboratories need external quality assessment?
Laboratories can easily determine the precision of their methods by calculating the mean, SD, and CV from recent control results. Reliable estimates of precision performance are available as long as there is enough data obtained over a long enough period of time.
What is IQCP in labs?
IQCP is an all-inclusive approach to assuring quality. It includes many practices that a laboratory already uses to ensure quality testing beyond requiring that a certain number of QC materials be tested at a designated frequency. IQCP applies to all nonwaived testing performed, including existing and new test systems.
What is QC in laboratory?

Is the EQC a good pick?
Verdict The EQC isn' t the quickest pick in its class, but it's an excellent choice if you're looking for an electrified SUV that rates highly for comfort and luxury. By Warren Clarke.
Is the EQC cabin a luxury?
The EQC's cabin would have provided more outright luxury than buyers will find in rivals such as the Tesla Model X and Jaguar I-Pace. The construction was solid, the execution was impeccable, and the quality of the materials used was above reproach. The high-quality cabin is yet another reason to be disappointed in the EQC's cancellation. Mercedes never disclosed final cargo capacity for this SUV. However, as a reference point, the GLC-class upon which the EQC would have been based provides about 19 cubic feet of cargo space behind its rear seats.
What is IQCP in testing?
IQCP provides a framework for customizing a QC plan for your test systems and your laboratory’s unique environment. By performing the steps in IQCP, the laboratory will examine the potential sources of error more thoroughly and determine the appropriate QC or quality practices to address them. After the laboratory completes this process, it is possible that the laboratory may determine that the amount of QC the laboratory has been doing all along is sufficient. However, the laboratory may discover potential sources of error that have not previously been considered, and may need to implement additional QC.
Who is responsible for IQCP?
The technical consultant/supervisor is responsible for establishing IQCP as part of the laboratory’s overall quality control program. The LD may assign, in writing, specific portions of IQCP tasks to other laboratory individuals. However, the LD remains responsible for the IQCP, and all CLIA personnel requirements must continue to be met.
What is the IQCP workbook?
The IQCP workbook, "Developing an IQCP A Step-by-Step Guide" published by the CDC and CMS([email protected]), provides a helpful list of Risk assessment questions that may guide the reader in regards to evaluation risks surrounding specimen collection, the test system, reagents, and environment and testing personnel.
What should a surveyor write in IQCP?
Since IQCP is voluntary, the surveyor should write the deficiency against the CLIA QC regulation that the laboratory failed to follow . (The laboratory can include in their response that they are correcting the deficiency by either following the CLIA QC regulation as written or implementing IQCP.)
When performing a risk assessment for a single test system that tests for multiple analytes, should the laboratory?
When performing a risk assessment for a single test system that tests for multiple analytes, the laboratory should consider the potential sources of error that apply to the test platform overall, plus any potential sources of error that are specific to each of the individual analytes, as applicable. These types of risks can be incorporated in a single risk assessment for the test system.
Is IQCP the same for each test system?
While the methodologies are similar, the test systems are not identical. It is likely that while some potential sources of error will be similar, others will be unique to each test system. Therefore, the laboratory must perform a separate IQCP for each individual test system.
Do labs have to follow IQCP?
The laboratory must be either following the CLIA QC regulations or implementing IQCP. If the lab chooses to implement an IQCP, the associated QCP may not be less stringent than the manufacturer’s QC requirements. And laboratories implementing IQCP for new tests are encouraged to perform control procedures at more frequent intervals during initial implementation, allowing the laboratory to identify performance issues that could indicate a need to adjust the QCP.
What is IQCP in labs?
The "Individualized Quality Control Plan ” (IQCP) is the Clinical Laboratory Improvement Amendments (CLIA) Quality Control (QC) procedure for an alternate QC option allowed by 42CFR493.1250.

Between now and the implementation date, laboratories may: 1) follow CLIA QA requirements as written; 2) continue to use EQC; or 3) implement IQCP.
Why do laboratories need IQCP?
Laboratories will need to assess their current quality practices as they apply to test systems, clinical use of technologies, patient populations , etc. Because it is risk-based, an IQCP may result in quality control that is less stringent than the CLIA QC requirements. However, if a manufacturer’s instructions are less rigorous than ...
What is QA in lab?
Quality Assessment (QA) is a method of surveying QCP effectiveness/performance through ongoing laboratory monitoring and review of documentation generated as part of the QCP. Monitoring is not limited to one-time data review, but includes trending over time. Documentation examples include quality control review, results of proficiency testing and competency assessments, patient test result review, specimen rejection rates, test turnaround times, and corrective/preventive action and follow-up records. The assessment may identify a lack of effectiveness, unanticipated failures, or underestimated risks requiring identification of root cause, corrective action and preventive action, and follow-up. Conversely, it may identify reliable performance that qualifies for less stringent quality control. Either finding may result in modification of the QCP, making it a “living” document.
What is QCP in testing?
The QCP describes practices, resources, and procedures necessary to control the quality of a given test process. Using risk profiles, laboratories may determine that an individual test requires an individual QCP, or that tests with similar risk profiles may be grouped together in a single QCP.
