How are you? Glomerular filtration rate or its approximation of the creatinine clearance are measured whenever renal disease is suspected or careful dosing of nephrotoxic drugs is required. The normal ranges of GFR, adjusted for body surface area for males is 70 ± 14 mL/min/m2 (56-84) . Risk factors for kidney disease include diabetes, high blood pressure, family history and older age.
Take care and keep us posted.
