estimates GFR based on age, race, sex, and serum creatinine.
When the MDRD
equation was used, 2% of patients had stage 1 chronic kidney disease, 59% had stage 2, 38% had stage 3, and 1% had stage 4.
Using the 4-parameter MDRD
equation, we compared the eGFR calculated from creatinine values obtained by various field methods between 2006 and 2011.
study demonstrated that the eGFR correlated well with mGFR determined by urinary clearance of 125I-iothalamate in the CKD patients in the lower eGFR <60 ml/min/1.
equation estimates of glomerular filtration rate in potential living kidney donors and renal transplant recipients with impaired graft function.
Mean standard scores for Studies 1 to 4, respectively, were 86, 86, 88, and 85 for MD-only and 82, 79, 81, and 80 for MDRD
on WRAT-Arithmetic; 105, 108, 105, 103 for MD-only and 82, 80, 78, and 78 for MDRD
on WRAT-Reading; and 94, 97, 92, and 91 for MD-only and 87, 84, 85, and 84 for MDRD
on WASI IQ.
Additional new CKD clinic in NE Calgary to accommodate the growing CKD patient population with MDRD
GFR < 30
Although creatinine levels alone are relatively inaccurate in determining the presence of kidney disease, especially mild kidney disease, physicians can estimate GFR using standard equations such as the Cockroft-Gault or the MDRD
(modification of diet in renal disease) (Table 4) that are available on the NKF web site.
equation can be applied to a single blood sample to accurately detect CKD in patients with heart disease, Brosius said.
Please note that the African-American factor is not used in Australia and as the MDRD
formula has not been validated in children, its use should be restricted to people over 18 years of age.
formula in partial nephrectomy has been used to provide an appropriate estimate of renal function despite its limitation application in the partial nephrectomy population (typical patients with a normal contralateral kidney).
Although the MDRD
equation works very well for patients with CKD, the population in whom it was developed, it works less well for other groups.
