Quality Control is test specific while Quality Assurance encompasses the quality from the start to the end of the process.Thus, Quality control is the process of ensuring that products or services meet specific standards, while quality assurance focuses on implementing systems and procedures to prevent defects from occurring in the first place.

The Levey–Jennings chart is a type of statistical process control (SPC) chart, typically used in laboratory quality control applications.
It uses the long-term (overall or population) estimate of sigma instead of the short-term (i.e., within subgroup or sample) estimate of sigma.

Material management plays a crucial role in clinical laboratory settings and in our daily lives. In a clinical laboratory, proper material management ensures that all necessary equipment and supplies are available, in good condition, and properly maintained to conduct accurate and reliable tests. This helps to ensure patient safety, improve the…[Read more]

controls are reference materials or samples used in clinical laboratories to monitor the accuracy and precision of laboratory test results. They are run alongside patient samples to ensure that the laboratory test is performing within acceptable limits.

Positive controls contain a known amount of the analyte of interest within the detectable…[Read more]

A standard in a clinical laboratory is a substance or material with a known concentration, purity, or activity that is used as a reference point for testing and calibration. It is a crucial element in quality control measures, ensuring the accuracy and reliability of laboratory test results. Standards are typically traceable to national or…[Read more]

Procedures provide detailed instructions for specific tasks, processes describe the overall workflow, and policies provide guidelines for decision-making and compliance with regulations.

Accuracy and precision are two important concepts in measurement and experimentation that can provide valuable insights into the reliability and validity of data. Accuracy refers to how close a measurement is to the true or expected value, while precision refers to the consistency and reproducibility of a measurement. Together, these two…[Read more]

Laboratory Controls is a point of comaparison when initiating certain tests.

I’ve had a few people ask WHY we test internal controls, so I thought I’d make this short overview about why and how we test internal controls, analyse the r…

Accuracy is how closer you are to the true value while precision is getting the same value at random repetition.

System Analysis and Design is a formal process of studying a problem and creating a solution.
