Glomerular Filtration Rate |
||
|
Enter the blood creatinine level in the form below to calculate
the estimated glomerular filtration rate using the CKD-EPI formula,
and also the actual GFR if you enter the body surface area or
the weight and height of the subject.
This calculator also uses the stochastic function depicted in Figure 1 (top pannel) of Levey 2009 to estimate the probability that the patient has various degrees of renal failure given the creatinine level. Sometimes, an estimate in the normal range may be associated with a substantial probability that the patient has low GFR and viceversa, an estimate in the pathologic range could occur even if the patient actually has fairly good GFR. Depending on the reason for which the GFR is estimated, a substantial probability of misclassification may warant further investigation.
