The most likely cause of the turbidity is:
a. fat
b. white blood cells

c. fixed around 1.010
d. fixed around 1.020☑️Correct Ans-C
34) The fluid leaving the glomerulus normally has a specific gravity of::
a. 1.001
b. 1.010

6) The following results were obtained on a urine specimen at 8:00 AM:
pH: 5.5; protein: 2+; glucose: 3+' ketones: 3+; blood: negative; bilirubin: positive; nitrite:
positive

which of the following test results would be changed due to these storage conditions:
a. glucose
b. ketones
c. protein

9) A 24-hour urine from a man who had no evidence of kidney impairment was sent to the
laboratory for hormone determination. The volume was 600 mL, but there was some question as
to the completeness of the 24-hour collection. The next step would be to:
a. perform the hormone determination, since 600 mL is a normal 24-hour urine volume
b. check the creatinine level; if it is <1g, do the procedure
c. report the hormone determination in mg/dL in case the specimen was incomplete
d. check the creatinine level; if it is >1g, do the procedure☑️Correct Ans-D
11) eGFR calculated by the MDRD formula takes into account the age, BUN, age, race, albumin
and what else for its calculations?
a. urea
