Gfr six formulas
WebLater applications of CG most often adjust for ideal body weight, given the higher body weights of today versus those in 1976. Interestingly, CG adjusted for ideal body weight is less accurate at estimating GFR than unadjusted weight. 5, 25 – 28 CG accurately estimates GFR 66% of the time when adjusted for ideal body weight, compared to 73% ... WebAll equations underestimated the measured GFR except the simple cystatin C formula, which slightly overestimated the measured GFR. All equations lacked precision. The ability to correctly estimate the patient's GFR was high for all equations (87.3-91.9%), except for the Larsson formula, with which 29.2% of subjects were misclassified.

WebGFR is measured in mL/min/1.73m 2. In case of children it is used the Schwartz formula: - The GFR = 0.41 * Height (in cm) / S Cr. When the child’s height is expressed in inches, the height should be converted from inches to centimeters: 1 inch = 2.54 cm. Related to the optimal GFR level, the 60mL/min/1.73m 2 level is adequate.
