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 charts are used to record the results of measurements on control samples to determine if there are systematic or random errors in the method being used. The most common type of chart is the Levey-Jennings chart.
There should be a separate control chart for each method being monitored and separate charts for normal and abnormal controls. The mean and standard deviation of the control being used should be noted on the chart. These should be determined based on at least 20 measurements over 20 days.
Each time the control is tested, the result is marked on the chart at the appropriate standard deviation level. For instance, if the mean for a control is 15 and the standard deviation 5, if you test a control and get a value of 22.5, the chart is marked at +1.5 SD for that day.
What is the importance of material management in the laboratory and in your life?
For a laboratory to operate effectively and efficiently, material management is essential. Managing inventory and supplies enables the laboratory to be whole, making sure that supplies do not lack so when it counts, the laboratory would be able to make the right diagnosis, utilizing different materials and equipment, and save lives. This makes material management vital in the laboratory setting.
Material management can also be helpful in a number of ways in my personal life. Organizing my own academic needs, such as my school supplies, is one example. There are also instances like running out of ink, papers, and even my own budget for food, which would be solved through proper material management. In reality, using appropriate material management techniques helps me become more organized, efficient, and prepared in my life as a student and overcome different obstacles.
Standards in the laboratory setting refer to a set of guidelines, protocols, and procedures that ensure consistency, accuracy, and reliability of laboratory results. These standards may include guidelines for laboratory equipment, analytical techniques, quality control, data analysis, and reporting.
On the other hand, controls are critical components of laboratory procedures, and their use helps to ensure that laboratory results are accurate, precise, and reliable.
