Discuss the biological & analytical variation that will influence the results interpretation in URINALYSIS.

Solutions

Expert Solution

Urinalysis is the gross, histological, biochemical and microscopic examination of the urine specimen.
Some of the common biological and analytical factors that may interferre with the urinalysis results are:

1. container for specimen collection : a container that is unsterile and contaminated with other microbes may give false results.
2. similarly infected, unsterile pipettes and slides can also interferre with the results.
3. Storage of the specimen is also important. If the specimen is collected sometime before the tests it should be preserved in the refrigerator. Improper storage may cause bacterial growth.
4. A thorough drug history of the patients should be taken. Some drugs may interferre with urinalysis and should be stopped before the test.
5. Some dyes and vitamins also interferre with the test.
6. the time at which the urine is collected may also interferre with test results. First urine in the morning is usually recommended.

Discuss how choosing a significance level of 90%, 95%, or 99% might influence the results of our analysis as well as the factors you might consider in making your choice. Consider and discuss how doing the wrong thing (alpha risk, implementing when the improvements aren’t significant) might be perceived differently than choosing to do nothing yet (beta risk, going back for more design when the improvements are significant). How might you approach this analysis of your two data samples
