What is patient has blood glucose of 200 mg / dl, GFR = 90 ml / min, transport maximum for glucose = 150 mg / min. What is the amount of glucose excreted? and explain in detail?
Blood glucose
= 200 mg /dl = 200 mg / 100 ml
= 2 mg / ml
Filtered load of glucose  
= GFR × Blood glucose
= 90 × 2
= 180 mg/min
Amount of glucose excreted = Filtered load – Transport maximum
= 180 – 150
= 30 g/min
