What is the difference between screen threshold and confirmation threshold in drug testing?
The screen threshold is the amount, usually milligrams per deciliter (mg/dL) of sample, that must be present in a specific lab specimen for the test to return a positive. Usually the screen threshold for a drug test is high, meaning drugs or drug metabolites must be present in great amount for the test to return positive. The result is that many drug tests come back negative although the sample does in fact contain drugs or drug metabolites. Any positive specimen is then analyzed by lab machine which detects almost any trace amount of drugs or drug metabolites.

What is difference between identification threshold and qualification threshold in impurity?
The identification threshold in impurity testing is the level at which it is possible to detect the impurity, while the qualification threshold is the level at which the impurity is deemed to be significant enough to potentially affect the quality, safety, or efficacy of the product. Identification threshold is usually lower than the qualification threshold.

Difference between functionality testing and load testing?
Functionality testing is what is expected. Load testing is what it actually did.
What is difference between regression and confirmation testing?
Regression testing and confirmation testing are both important parts of the software testing process, but they serve different purposes. Confirmation testing (also called re-testing) is done to verify whether a specific bug or defect that was reported earlier has been successfully fixed. It focuses only on the particular issue that was identified and ensures that the fix works as expected. Regression testing, on the other hand, is performed after confirmation testing to check whether the recent changes (like bug fixes or new features) have affected the existing functionality of the application. It helps ensure that no new issues have been introduced elsewhere in the system. Both testing types are essential for maintaining software quality. If you're learning about these testing strategies in depth, institutes like Uncodemy include them as part of their software testing training, combining theory with hands-on practice to help students understand real-world QA scenarios.
What is the major difference between regression testing and retesting?
regression testing is a white box testng
What is the difference between testing a single mean and testing the difference between two means?
A single mean is used in testing to compare a single variable to a population mean in order to determineÊif there is aÊdifference. Two means are used in testing to compare two populations to see if there are variances between the two variables.Ê
