Demographic data, such as age, gender, weight, height, body mass index (BMI) and BSA, were recorded. eGFR C − G ( ml / min ) = ( 140 − age in years ) × ( weight in Kg ) × 1.23 if male ( 1.04 if female ) / SCr in μ mol / L .
Your healthcare team will do a simple blood test to find out your eGFR. They will also do a urine albumin-to-creatinine ratio (UACR), which shows if you have protein (albumin) in the urine. Protein in the urine may mean you have kidney damage. Control blood pressure if you have high blood pressure.
Cockcroft-Gault equation is often used as a method of estimating GFR (although it was developed as a method of predicting creatinine clearance) from knowledge of serum creatinine, age and weight: creatinine clearance = (((140 - age in years) x (wt in kg)) x 1.23) / (serum creatinine in micromol/l)
Creatinine Clearance Calculator Calculation information: This formula is applicable only if the serum creatinine is stable. Est. Creatinine Clearance = 140 - age(yr)weight(kg)/72serum Cr(mg/dL) (multiply by 0.85 for women).
EGFR may also be calculated using the level of cystatin C in your blood. This is a protein that many cells in your body make. Cystatin C levels are not affected by muscle size, age, or diet, so some researchers think cystatin C provides a more accurate estimate of GFR than creatinine.
Equations eGFR = 142 × min(SCr/κ,1)α × max(SCr/κ,1)-1.200 × 0.9938Age × 1.012 if female Table 1. eGFR = 135 × min(SCr/κ,1)α × max(SCr/κ,1)-0.544 × min(Scys/0.8,1)-0.323 × max(Scys/0.8,1)-0.778 × 0.9961Age × 0.963 if female Table 2.
Laboratory methods We compared new equations to the MDRD Study equation, given by: estimated GFR = 175 × standardized Scr −1.154 × age−0.203 × 1.212 if black × 0.742 if female, where GFR is expressed as mL/min/1.73 m2 of body surface area41 and Scr is expressed in mg/dL(4).
The prediction of creatinine clearance (in ml/min) by the Cockcroft-Gault formula (3) was calculated as (140 − age) × body weight/plasma creatinine × 72 (× 0.85 if female).
What is the Rule for Standard Form? Standard form for linear equation in two variables x and y is given as Ax + By = C, where A, B, and C are integers, and A is non-negative, and, A, B, and C have no common factors other than 1.
The general form ax+by+c=0 is one of the many different forms you can write linear functions in. Other ones include the slope intercept form y=mx+b or slope-point form.
