Creatinine can be used to calculate the glomerular filtration rate. However, a small amount of it is secreted, so it is not completely accurate. What can be used to calculate glomerular filtration rate instead?

Given that the average filtration fraction of the plasma is 20%, how can the PAH clearance of plasma be equivalent to the renal plasma flow?

What is the term for the percentage of whole blood that consists of blood cells? It is required to calculate renal blood flow.

Why might it be difficult to test the glomerular filtration rate using inulin clearance?

What is the clinical significance of calculating renal function?
