How do i work out the urinary concentration of glucose using these figures:
Plasma glucose concentration: 18mmol/l
Urinary glucose excretion rate: 0.18mmol/min
Glomerular Filtration rate: 125ml/min
Urine Flow rate: 2ml/min
im so confused!!

maybe, if you better described, what are these numbers supposed to mean ;)

Cis or trans? That's what matters.

This is an easy one. The equation is Excretion rate = Urine Flow rate X Urine concentration

The units match too, You have 0.18 mmol/l = 2ml/min (convert ml to liter) x (???) mmol / liter

Just divide and you get the concentration urine concentration of glucose.

Now do you need help finding the clearance of glucose too, cause thats when you will need the plasma glucose and GFR. You dont need to them for excretion.
