MLT 112 STUDY QUESTIONS—Chapter 61.State an advantage and a disadvantage of performing urine microscopics based on macroscopic screening.2.List the seven parameters commonly used as markers in macroscopic screening. Which is most likely to result in a non-clinically significant microscopic? Why?3.What is the unique advantage to laboratory personnel provided by the Cen-Slide and R/S 2000 microscopic systems?4.State three conditions that can occur prior to a specimen being poured into a centrifuge tube that can produce false-negative microscopic results.5.Why should a laboratory be consistent in the volume of urine used to prepare the sediment? 6.Why should specimen centrifugation be standardized in terms of relative centrifugal force rather than revolutions per minute?7.State an error in centrifugation technique that can produce falsely decreased sediment constituents and an error that can compromise laboratory safety.8.Calculate the sediment concentration factor if 15 mL of urine is centrifuged and 14.5 mL of specimen is decanted. If only 14 mL of specimen is decanted, how would this affect the sediment?
