Excellent preservative for urine sediment?
a. Ethyl

c. Sodium chloride
d. Formalin
d. Formalin
A technologist performed a STAT microscopic urinalysis and reported the following: WBC (10-13), RBC (2-6), Hyaline Cast (5-7), Bacteria (Moderate). The centrifuge tube was not discarded and the urine sediment was reevaluated on the microscope 5 hours after above result was reported. The second technologist reported the same results, except the Bacteria (plenty) and Hyaline Cast (none). The most probable explanation for second technologist’s findings is;
a. Cast dissolve due to the increase in urine pH.
b. Cast dissolve due to the decreaseurine pH.
c. Cast were never present in this specimen.
d. Sediment was not agitated before preparing the microscope slide
a. Cast dissolve due to the increase in urine pH.

d. Presence of a neutral pH
b. Specific gravity of less than 1.007
Which of the following crystal may be found in acidic urine?
