Feedback
Westgard R4S rule: this rule applies when the difference between the highest and
lowest result of a run exceeds 4 standard deviations (SD). For example, on day
one the control is at +2SD. On day two, the same control is at -2SD. This rule
detects random errors. The run is rejected.

C) Waxy casts
D) Red blood cell casts - CORRECT ANSWER B) Positive protein
Feedback
The macroscopic abnormalities are detected by the physical and chemical portions
of the urinalysis. Obtaining a positive protein during the chemical portion of a
urinalysis would be an example of a macroscopic abnormality.
The presence of glitter cells, waxy casts, and red blood cell casts could only be
determined by the microscopic examination of the urine sample.
Which bacterial species is most likely represented by the spreading, wrinkled, non-
hemolytic colony appearance as illustrated in the photograph?
