Ckd Staging Calculator

This equation is recommended when eGFR values above 60 mLmin173 m² are desired. It is used most widely by nephrologists and understood to be the most accurate means of non-invasively assessing GFR in the United States.

The CKD-EPI equation performs superiorly to the MDRD Equation in patients with normal or mildly reduced estimated GFR eGFR and just as well in patients with an eGFR of.

Ckd staging calculator. Use the chart below to determine which CKD stage best matches your GFR calculator results and click on the stage to learn about healthy next steps. Performs superiorly to the Cockcroft-Gault Equation. The CKD-EPI Chronic Kidney Disease Epidemiology Collaboration equation was developed in an effort to create a more precise formula to estimate glomerular filtrate rate GFR from serum creatinine and other readily available clinical parameters especially at when actual GFR is 60 mLmin per 173m 2.

Use the suffix p to denote the presence of proteinuria when staging chronic kidney disease CKD. Stage 3a G3a an eGFR of 45 to 59mlmin. Please note the calculator is not valid for people under the age of 18.

Waste products build up in the blood. Stage 1 G1 a normal eGFR above 90mlmin but other tests have detected signs of kidney damage. Stage 3 CKD a moderate decrease in kidney function is divided into 3A GFR is 45 to 59 and 3B GFR is 30 to 44The following can occur when someone is in stage 3 of CKD.

Stages of chronic kidney disease on the basis of GFR Defined by the level of GFR there are 5 stages of chronic kidney disease according to NKF-KDOQI Guidelines 1. The National Kidney Foundation recommends using the CKD-EPI Creatinine Equation 2009 to estimate GFR. Normal GFR varies according to age sex and body size and declines with age.

This CKD-EPI equation calculator should be used when S cr is reported in µmolL. The MDRD equation performs equally to the newer CKD-EPI Equation in patients with GFR of 60 mlmin173m2. Glomerular Filtration Rate Values are normalised to an average surface area size of 173 m 2.

Some pathology results may use an alternate formula which will result in slightly different result. This information forms the basis of CKD staging which is useful for planning follow up and management. The kidney failure risk equations were developed in patients with CKD stages G3-G5 referred to nephrologists in Canada and have now been validated in more than 700000 individuals spanning 30 countries worldwide.

90 Normal renal function but urinalysis structural abnormalities or genetic factors indicate renal disease. People in later stages CKD 4 and 5 may need to find a nephrologist and explore treatment options such as a kidney transplant or dialysis. If youre a health professional referencing a patients eGFR can be helpful in explaining what stage of kidney disease theyre in.

Your eGFR results is given as a stage from 1 of 5. Symptoms include fatigue too much fluid urination changes sleep problems and kidney pain. This calculator uses the CKD-EPI formula.

Patients with CKD can be classified depending on their level of kidney function or eGFR and the amount of protein present in the urine. Glomerular filtration rate GFR is the best overall index of kidney function. Researchers pooled data from multiple studies to develop and validate this new equation.

MDRD Study mlmin173 m 2 CKD-EPIcr mlmin173 m 2 CKD-EPIcys mlmin173 m 2 CKD-EPIcr-cys C mlmin173 m 2. GFR categories in CKD Category GFR mlmin173 m2 Terms G1 90 Normal or high G2 60-89 Mildly decreased G3a 45-59 Mildly to moderately decreased G3b 30-44 Moderately to severely decreased G4 15-29 Severely decreased G5. Stage 1 is the earliest while Stage 5 represents kidney failure or end-stage renal disease ESRD respectively.

Stage 2 G2 a slightly reduced eGFR of 60 to 89mlmin with other signs of kidney damage. GFR 141 min S cr κ 1 α max S cr κ 1 -1209 0993 Age 1018 if female 1159 if African American The equation does not require weight because the. This calculator returns the probability expressed as a percentage from 0 to 100 of having Stage 3-5 CKD defined as an estimated glomerular filtration rate eGFR less than 60 mLmin173m 2 based on nine input variables 1If one or more of the values is unknown trying different combinations of the presence or absence of the unknown characteristics will give a range of possible estimates.

NKF and the American Society of Nephrology have convened a Task. Identify cause of CKD C Assign GFR category G Assign albuminuria category A Collectively referred to as CGA Staging Assign GFR category as follows. The higher the stage G1-G5 and the greater the amount of protein present in the urine A1-A3 the.

Stage 3b G3b an eGFR of 30 to 44mlmin. Noninvasively estimates the measured GFR to determine degree or presence of decreased kidney function.
