Which of the following lab results would be associated with abnormalities in kidney function? Select all that apply
A)
An absence of protein in a urine sample
B)
Increased creatinine levels
C)
Urine gravity of 1.038 and normal serum creatinine levels
D)
Decreased blood urea nitrogen (BUN) level
E)
Detectable levels of glucose in a urine sample
F)
Elevated cystatin-C level.
Ans:
B, E, F
Feedback:
Increased creatinine and BUN are associated with abnormalities in renal function, as is the presence of glucose in a urine sample. Urine samples normally lack protein and have a specific gravity of 1.038 to 1.040. An elevated BUN coupled with normal creatinine is likely not attributable to impaired kidney function.
