Which of the following result shows renal impairment?
a. urea 9 mmol
b. creatinine 10 mmol/l
c. urates
d. cholesterol
e. urine osmolarity less than 800 after 12 hrs of water deprivation.
(e) A urine osmolarity less than 800 after 12 hrs of water deprivation denotes renal impairment.
Urea 9mmol is high normal (n: 2.9-8.2) and is not a very sensitive measure of GFR.
Creatinine, although a sensitive measure of GF, 10umol is normal (n: 53-106)
Cholesterol and urates are useless in this regard.
