The equation must be applied to a stable creatinine value, and is inaccurate when serum creatinine is rapidly changing. The equation is not useful in children with reduced muscle mass, amputations, cachexia, or those taking creatine supplements. What recommendations do you have for doctors once they have applied the Schwartz Equation for GFR?

2017年9月7日 · Program is based on the following equations: Schwartz equation: CrCl (ml/min/1.73m2)= [length (cm) x k] / Scr (Patient population: infants over 1 week old through adolescence (18 years old)) k = 0.45 for infants 1 to 52 weeks old k = 0.55 for children 1 to 13 years old k = 0.55 for adolescent females 13-18 years old k = 0.7 for adolescent males 13-18 years old Schwartz GJ, Haycock GB, Edelmann ...

This formula should not be used with serum creatinine measurements calibrated to reference measurements by isotope dilution mass spectroscopy (IDMS). See the Revised Schwartz Estimate . Many medications should be adjusted for renal impairment when the …

The pediatric GFR calculator is for use in children under 18 years old. For persons 18 and older, use the GFR calculator for adults.; If values for cystatin C and/or BUN are not entered, the calculator will generate GFR estimates using the creatinine-based “Bedside Schwartz” equation only (currently considered the best method for estimating GFR in children).

This formula may be most accurate in the range of 15 to 75 mL/min per 1.73 m 2. Values >75 should be reported as such rather than as a ...

2024年10月3日 · 施瓦茨公式由George Schwartz博士于1976年开发，广泛用于估算儿童的肾小球滤过率（GFR）。GFR是肾功能的关键指标，施瓦茨公式对儿童尤为重要，因为精确的肾功能测量对于早期诊断肾脏问题至关重要。 计算公式. 计算GFR的施瓦茨公式如下：

How it works: Generate Traditional Schwartz Equation (1976) and Modified Bedside Schwartz Equation (2009) Formulas Used for eGFR Calculation1. Traditional 1976 Schwartz EquationeGFR = (K x Height (cm)) / Serum Creatinine (mg/dL)whereas K is selected based on age and gender (as per the criteria below).Age Categories and Corresponding K-ValuesThe Schwartz formula uses a proportionality constant

Original Schwartz Equations: eGFR = k x (height in cm) ÷ serum Cr; k = 0.33 in preemie infants; k = 0.45 in term infants to 1 year of age; k = 0.55 in children to 13 years of age; k = 0.70 in adolescent males (females remain at 0.55 after age 13 years) IDMS-Traceable Schwartz Equation: eGFR = (0.41 x height in cm) ÷ serum Cr
