Hey guys,
Could you help me out here. I don't seem to get the method to relate urine sodium level to whether it is a concentrated urine or dilated urine.
Example of a case of SIADH :
Serum osmolarity = 268 mOsm/kg and urine sodium level is 40 mEQ/L
The explanation to this question says that there is extensive renal salt wasting.
How do you see if there is extensive salt wasting or not? The lab reference values say urine sodium "varies with diet". What??
