IntroductionIn the realm of healthcare and medicine, the assessment of kidney function is of paramount importance. Two key parameters used for this purpose are the Glomerular Filtration Rate (GFR) and Creatinine Clearance. These values provide vital insights into the efficiency of the kidneys in filtering waste and excess substances from the blood. Calculating GFR from Creatinine Clearance or vice versa can aid healthcare professionals in diagnosing and monitoring kidney-related conditions. In this article, we will delve into the GFR to Creatinine Clearance Calculator, exploring its formula, how to use it, providing an example, and addressing some frequently asked questions.Formula:The formula to convert GFR to Creatinine Clearance and vice versa is as follows:Creatinine Clearance (CrCl) = (GFR x 1.73 x Body Surface Area) / 1.73Where:Creatinine Clearance (CrCl) is measured in mL/min (milliliters per minute).GFR stands for Glomerular Filtration Rate and is also measured in mL/min.Body Surface Area (BSA) can be calculated using various formulas, such as the DuBois and DuBois formula: BSA (m^2) = 0.007184 × (Weight^0.425) × (Height^0.725).How to Use?Using the GFR to Creatinine Clearance Calculator is a straightforward process. Follow these steps:Determine GFR Value: First, find the GFR value for the patient, typically obtained through blood tests and clinical assessments. GFR is a measure of how efficiently the kidneys filter waste from the blood.Calculate Body Surface Area (BSA): If not readily available, calculate the patient’s Body Surface Area using an appropriate formula, such as the DuBois and DuBois formula mentioned above.Apply the Formula: Plug the GFR and BSA values into the formula: CrCl = (GFR x 1.73 x BSA) / 1.73.Calculate Creatinine Clearance: Perform the calculations, and you will obtain the Creatinine Clearance value in mL/min.Example:Let’s illustrate the use of the GFR to Creatinine Clearance Calculator with an example:Suppose a patient has a GFR of 80 mL/min, and their Body Surface Area (BSA) is 1.7 m^2. Using the formula:CrCl = (80 x 1.73 x 1.7) / 1.73After simplification, the Creatinine Clearance (CrCl) is found to be approximately 136 mL/min.FAQs?Q1: What is Glomerular Filtration Rate (GFR)?A1: GFR is a measure of how efficiently the kidneys filter waste and excess substances from the blood. It’s a crucial indicator of kidney function.Q2: Why is Creatinine Clearance important?A2: Creatinine Clearance is used to estimate the rate at which the kidneys are removing waste and excess substances from the blood, helping diagnose and monitor kidney-related conditions.Q3: Can I calculate BSA manually?A3: Yes, BSA can Dose is missed it should be taken as soon as the patient remembers and then treatment should be continued as prescribed. Double doses should not be taken to compensate for a missed dose.Additional information on special populations: Children and adolescents: For recommended dosage regimen, see Tables 3 and 4.Geriatric patients: Elderly patients should receive a dose as low as possible depending on the severity of their illness and the creatinine clearance (see also Patients with renal and hepatic impairment).Patients with renal and hepatic impairment: Adults: Patients with renal impairment: Film-coated tablet: See Table 5.Click on icon to see table/diagram/image Solution for infusion: See Table 6.Click on icon to see table/diagram/image Patients with renal impairment on hemodialysis: Film-coated tablet: For patients with creatinine clearance between 30 and 60 mL/min/1.73 m2 (moderate renal impairment) or serum creatinine concentration between 1.4 and 1.9 mg/100 mL, the maximum daily oral dose of ciprofloxacin should be 1000 mg.For patients with creatinine clearance less than 30 mL/min/1.73 m2 (severe renal impairment) or serum creatinine concentration equal or higher than 2.0 mg/100 mL, the maximum daily oral dose of ciprofloxacin should be 500 mg on dialysis days after dialysis.Solution for infusion: For patients with creatinine clearance between 30 and 60 mL/min/1.73 m2 (moderate renal impairment) or serum creatinine concentration between 1.4 and 1.9 mg/100 mL, the maximum daily intravenous dose of ciprofloxacin should be 800 mg.For patients with creatinine clearance less than 30 mL/min/1.73 m2 (severe renal impairment) or serum creatinine concentration equal or higher than 2.0

Is solely filtered out of the blood but NOT reabsorbed back into the system. It is excreted out through the urine. This is why a creatinine clearance test is used as an indicator for determining renal function and for calculating the glomerular filtration rate.2. A patient with acute renal injury has a GFR (glomerular filtration rate) of 40 mL/min. Which signs and symptoms below may this patient present with? Select all that apply:A. HypervolemiaB. HypokalemiaC. Increased BUN levelD. Decreased Creatinine levelThe answers are A and C. The glomerular filtration rate indicates how well the glomerulus is filtering the blood. A normal GFR tends to be 90 mL/min or higher. A GFR of 40 mL/min indicates that the kidney’s ability to filter the blood is decreased. Therefore, the kidneys will be unable to remove waste and excessive water from the blood…hence hypervolemia and an increased BUN level will present in this patient. The patient will experience HYPERkalemia (not hypo) because the kidneys are unable to remove potassium from the blood. In addition, an INCREASED creatinine level (not decreased) will present because the kidneys cannot remove excessive waste products, such as creatinine.3. You’re assessing morning lab values on a female patient who is recovering from a myocardial infraction. Which lab value below requires you to notify the physician?A. Potassium level 4.2 mEq/LB. Creatinine clearance 35 mL/minC. BUN 20 mg/dLD. Blood pH 7.40The answer is B. A normal creatinine clearance level in a female should be 85-125 mL/min (95-140 mL/min males). A creatinine clearance level indicates the amount of blood the kidneys can make per minute that contain no amounts of creatinine in it. Remember creatinine is a waste product of muscle breakdown. Therefore, the kidneys should be able to remove excessive amounts of it from the bloodstream. A patient who has experienced a myocardial infraction is at risk for pre-renal acute injury due to decreased cardiac output to the kidneys from a damaged heart muscle (the heart isn’t able to pump as efficiently because of ischemia). All the other labs values are normal.4. A 55 year old male patient is admitted with a massive GI bleed. The patient is at risk for what type of acute kidney injury?A. Post-renalB. Intra-renalC. Pre-renalD. Intrinsic renalThe answer is C. Pre-renal injury is due to decreased perfusion to the kidneys secondary to a cause (massive GI bleeding…patient is losing blood volume).

Interpretation Provides information to assist in interpretation of the test results Decreased creatinine clearance indicates decreased glomerular filtration rate. This can be due to conditions such as progressive renal disease, or result from adverse effect on renal hemodynamics that are often reversible including certain drugs or from decreases in effective renal perfusion (eg, volume depletion or heart failure). Increased creatinine clearance is often referred to as "hyperfiltration" and is most commonly seen during pregnancy or in patients with diabetes mellitus, before diabetic nephropathy has occurred. It also may occur with large dietary protein intake. Cautions Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances Intraindividual variability in creatinine excretion may be due to differences in muscle mass or amount of ingested meat. Acute changes in glomerular filtration rate, before a steady state has developed, will alter the amount of urinary creatinine excreted.

Alternative treatment includes the use of denosumab, a monoclonal antibody that targets receptor activator of nuclear factor kappa-B ligand. Patients with Osteopenia in the Absence of Lytic DiseaseStarting bisphosphonates in patients with solitary plasmacytoma or smoldering (asymptomatic) or indolent myeloma is not recommended. Adjunct to Pain ControlIntravenous pamidronate or zoledronic acid is recommended for patients with pain as a result of osteolytic disease and as an adjunctive treatment of patients receiving radiation therapy, analgesics, or surgical intervention to stabilize fractures or impending fractures. Denosumab is an additional option. Patients with Myeloma with Normal Plain Radiograph or Osteopenia in Bone Mineral Density MeasurementsThe Expert Panel supports starting intravenous bisphosphonates in patients with multiple myeloma with osteopenia (osteoporosis), but no radiographic evidence of lytic bone disease. Patients with Monoclonal Gammopathy of Undetermined SignificanceStarting bisphosphonates in patients with monoclonal gammopathy of undetermined significance is not recommended, unless osteopenia (osteoporosis) exists. Dosing and SelectionAs a result of increased concerns over renal adverse events, dosing guidelines for patients with preexisting renal impairment were added to the zoledronic acid package insert. Guidelines recommend that patients with preexisting mild-to-moderate renal impairment—estimated creatinine clearance, 30 to 60 mL/min—should receive a reduced dosage of zoledronic acid. No changes in infusion time or interval are required. Zoledronic acid has not been studied in patients with severe renal impairment and. Home Medical Calculator Creatinine Clearance – MULTI-CALC.
