Ideal and Adjusted Amputation Body Weightįor patients without amputations, an ideal body weight equation (as described by Devine 1974) is calculated according to the equation below. The corrected GFR is approximately 8 lower in women than in men, and declines with age at an annual rate of 1 mL/min/1.73m 2 from the age of 40. The following estimates are reasonable for determining a patient's amputation ideal body weight (or adjusted body weight for overweight patients). The normal corrected GFR is 80-120 mL/min/1.73m 2, impaired renal function is 30-80 mL/min/1.73m 2 and renal failure is less than 30 mL/min/1.73m 2. The additional proximal tubule secretion falsely elevates the CrCl estimate of GFR. An EBWL-adjusted ideal body weight is most commonly used for determining renal function with creatinine clearance. Creatinine clearance ( CrCl) is an estimate of Glomerular Filtration Rate ( GFR ) however, CrCl is slightly higher than true GFR because creatinine is secreted by the proximal tubule (in addition to being filtered by the glomerulus). EBWL is most commonly utilized for determining an amputee's ideal body weight, which is a function of patient height. Knowing your eGFR and understanding which stage you’re in can help you take steps to preserve kidney function and track any progression.Estimated body weight loss (EBWL) describes the amount of body mass lost due to an amputation. If your doctor is using eGFR to help diagnose kidney disease or determine your stage, you may also need additional tests to confirm.

In some cases, your doctor may order a urine creatinine clearance test, as well. This can mean something different for everybody, since your eGFR also depends on your age, gender, muscle mass, ethnicity, and the results of your creatinine serum test.

Your eGFR is an important calculation that helps your doctor determine your level of kidney function. In some cases, your care team may recommend modifying your daily routine to incorporate an exercise program and a kidney-friendly diet. Note: Creatinine clearance reference intervals are based on a body surface area of 1.73 m 2. Female: younger than 12 years: 5090 mL/minute, 12 years and older: 88128 mL/minute. If you are diagnosed with chronic kidney disease, it’s also important to understand the root cause of the condition in order to protect your remaining kidney function and keep your GFR levels in a healthy range, Managing other conditions like high blood pressure or diabetes can help you stay healthy and slow the progression of CKD. Male: younger than 12 years: 5090 mL/minute, 12 years and older: 97137 mL/minute. To help preserve your current kidney function, talk to your care team about how you can protect your kidney health. It also varies from person to person based on age, gender, muscle mass, and ethnicity. Your eGFR tells you how well your kidneys are working, and can be affected by many factors, including your activity level, the foods you eat, and any kidney-related health conditions you have. Knowing your eGFR is also important to managing your health at every stage of kidney disease.

If your eGFR is below 90, your kidneys may not be functioning as well as they should and you may be at risk for kidney disease.īy estimating your GFR, along with other blood and urine tests-such as creatinine clearance-your doctor is able to diagnose kidney disease, determine which stage you’re in, and track any progression. The typical range for men, 19 to 75 years old, is 77 to 160 mL/min/BSA. Your estimated glomerular filtration rate (eGFR) is the calculation that indicates your level of kidney function, based on the results of a creatinine serum test and other factors-such as age, gender, muscle mass, and ethnicity. Creatinine clearance is reported as milliliters of creatinine per minute per body surface area (mL/min/BSA). Instead, our GFR calculator will give you an estimate using a mathematical formula that most closely determines your kidney function based on certain personal factors and your serum creatinine-which is the amount of creatinine in your blood. Your exact GFR cannot be measured directly. Just as your blood pressure and cholesterol levels are important factors in knowing your risk for heart disease, your GFR is important in knowing your risk for CKD. The CRCL calculator determines the creatinine clearance rate in mL/min and other indicators of body health such as body surface area in m 2, body mass index, ideal body weight and lean body mass.

Glomerular filtration rate is a measurement of how well your kidneys are working to clean your blood.
