Creatinine is assayed using methods that are traceable to IDMS assigned NIST certified reference materials. Clinical Use. Estimates GFR adjusted for body surface area. Designed for use with laboratory creatinine values that are References. MDRD STUDY EQUATION: mdrd (Age, Race, Gender, Plasma creatinine) Chronic kidney disease (GFR less than 60 or kidney damage for at least three months) *All ethnic groups other than African American Shortcut: Type underlined letters to toggle between variables We describe the results of the intention-to-treat analyses of the Modification of Diet in Renal Disease (MDRD) Study, which included two randomized, multicenter trials involving a total of 840 The MDRD trial sought to assess whether dietary and blood pressure changes can similarly delay worsening renal insufficiency in humans. The study involved both patients with moderate (glomerular filtration rate or GFR between 25-55 mL/min/1.73m 2 ) and severe renal insufficiency (GFR 13-24 mL/min/1.73m 2 ), and randomized patients to different levels of protein intake and blood pressure control. Patients with chronic kidney disease, to estimate kidney function. The MDRD equation cannot be used for acute renal failure.
