Creatinine clearance is then calculated using the equation.
[creatinine] exceeds the upper reference limit. The influence of muscle bulk and, to a much lesser extent, dietary protein intake, on creatinine production, means that a (slightly) elevated [creatinine] may not indicate impaired renal function 4 Analytical considerations Analytical methods 1. Renal function is an indication of the kidney's condition and its role in renal physiology.. Glomerular filtration rate (GFR) describes the flow rate of filtered fluid through the newyearinfo.sitenine clearance rate (C Cr or CrCl) is the volume of blood plasma that is cleared of creatinine per unit time and is a useful measure for approximating the GFR.. Creatinine clearance exceeds GFR due to.
