In the world of medical testing performing a Quality Control (or QC) test means assessing a measurement systems performance using predefined standards. The aim is to gain confidence that analytical results are consistent, comparable, accurate and within the specified limits of precision.
Quality control (QC) is one of the most important impacts on laboratory testing—it ensures both precision and accuracy of patient sample results. The integrity of quality control samples is important to both management of overall quality as well as to meeting requirements of proficiency testing.
Goal is to show that the testing system is operating within acceptable limits and the results are accurate. It uses basic statistical analysis and other analyses to determine that equipment, reagents, and operators are functioning correctly.
The purpose of including quality control samples in analytical runs is to evaluate the reliability of a method by assaying a stable material that resembles patient samples.
It is widely accepted that laboratories should perform QC at least every day of patient testing.
Quality control (QC) is a foundational practice in the clinical laboratory and is a routine and mandatory task. QC encompasses the analysis of QC materials and comparison of the observed values to the expected distribution under stable operating conditions.
"The laboratory must establish and follow written quality control procedures for monitoring and evaluating the quality of the analytical testing process of each method to assure the accuracy and reliability of patient test results and reports."
When should QC samples be run in the clinical laboratory? Every day that patient tests are performed. What is the significance of the numbers 0-4 in the diamonds on the four-color chemical label?
Solution or chemical substance of known concentration that mimics a patient's specimen is collected, processed, and manufactured commercially. A minimum of 2 QC samples must be analyzed at least once per day for each analyte to detect immediate errors.
Quality is Critical to Satisfied Customers Quality is critical to satisfying your customers and retaining their loyalty so they continue to buy from you in the future. Quality products make an important contribution to long-term revenue and profitability. They also enable you to charge and maintain higher prices.
In such a system, there are 3 main objectives of quality control: enhance product quality and reduce risks, gain production efficiencies, and garner customer loyalty.
Without a quality management system, a business will not be asked to bid on or be granted a contract, limiting the ability of the business to expand its outreach and position. A formal, well-executed TQM program is customer focused, and requires that a company constantly get better at making its products.
