It goes beyond traditional academic instruction, aiming to foster not only cognitive growth but also emotional intelligence, interpersonal skills, character development, and overall w…[Read more]

The Levey-Jennings chart is a graphical representation of Quality Control (QC) data commonly used in clinical laboratories to monitor the performance of a particular test over time. The chart is named after its developers, William A. Levey and Robert D. Jennings.

In the laboratory setting, quality control (QC) and quality assurance (QA) are two essential components of ensuring the accuracy and reliability of test results. While the terms are sometimes used interchangeably, they refer to distinct aspects of laboratory testing.

Quality control (QC) is the process of monitoring and verifying the performance…[Read more]

Quality Assurance is a process which focuses on providing assurance that quality request will be achieved. A QA aim is to prevent defect. Quality Control, on the other hand, is a process which focuses on fulfilling the quality request. A QC aim is to detect and improve the defects.

Quality Assurance refers to the maintenance of the intended quality level in the products/services right from the beginning while Quality Control is the system keeping the desired quality in the goods produced by testing the samples against the set criteria.

Quality Assurance is a set of activities for ensuring quality in the processes by which products are developed. On the other hand, quality control is a set of activities for ensuring quality in products. The activities focus on identifying defects in the actual products produced.

Quality control = ensures that the right things are being done; focuses on detecting and correcting issues
Quality assurance = ensures that results come out as expected; aims to improve processes to prevent things from going wrong in the future

QA vs QC

Quality assurance refers to the systematic and proactive approach to ensuring that products, services, and processes meet or exceed customer expectations. It involves creating and implementing policies, procedures, and standards that prevent defects or errors from occurring in the first place. QA focuses on prevention rather than…[Read more]

A Quality Assurance aim is to prevent the defect. A Quality Control aim is to identify and improve the defects. QA is the technique of managing quality. QC is a method to verify quality.

Levey-Jennings QC chart, also known as a control chart, is a graphical tool that is widely used in healthcare laboratories to monitor the quality of the results of diagnostic tests. It is named after two American statisticians, Levey and Jennings, who introduced this chart in 1950.

The chart consists of a series of data points plotted on a…[Read more]

Levey-Jennings charts are often used in laboratories to ensure that test methods are accurate. A control, with a known “true value,” is selected for a lab test, and is run on a regular basis (e.g., each shift, daily, or before each lab test). Each control result is plotted on the chart, and the generated standard deviation is utilized to set the…[Read more]

The Levey–Jennings chart is a type of statistical process control (SPC) chart, typically used in laboratory quality control applications. It is a chart that uses very similar to the Individual-Range chart, the major difference being that it only uses the Primary individual data point graph of the chart and does not include the Secondary range g…[Read more]

The Levey-Jennings quality control chart is a graphical representation of QC data used in the lab named after D.H. Levey and E.R. Jennings who developed the method. The chart is used to monitor the performance of an analytical method over time. Its purpose is to identify any systematic errors or changes in performance of the method. The chart is a…[Read more]

Levey-Jennings chart helps to identify trends or shifts in the data, which can indicate if the process is operating as expected or if there are issues that need to be addressed. By monitoring the data using this chart, it can help to ensure that the process is producing consistent and accurate results over time, which is essential in many…[Read more]
