What is BSA in creatinine clearance?
Creatinine clearance based on 24 hr collection of urine, corrected for body surface area. Calculates creatinine clearance in mL/min corrected for body surface area (BSA) as a measure of kidney function.
What is normal CrCl?
Normal Results Clearance is often measured as milliliters per minute (mL/min) or milliliters per second (mL/s). Normal values are: Male: 97 to 137 mL/min (1.65 to 2.33 mL/s). Female: 88 to 128 mL/min (1.496 to 2.18 mL/s).
What is CrCl level?
Creatinine clearance is one way to estimate your glomerular filtration rate (GFR), or how well the kidneys are filtering your blood. The GFR is the main number used by your provider to determine how well your kidneys are working. The creatinine clearance test is not used very often any more.
How do you calculate actual creatinine clearance?
Creatinine Clearance Calculator Creatinine Clearance = [[140 – age(yr)]*weight(kg)]/[72*serum Cr(mg/dL)] (multiply by 0.85 for women).
Why is creatinine clearance corrected?
Why Creatinine Tests Are Done Testing the rate of creatinine clearance shows the kidneys’ ability to filter the blood. As renal function gets worse, creatinine clearance also goes down. Your doctor may also order a creatinine test if you have symptoms of kidney disease, including: Nausea.
How is urine creatinine calculated?
Two hours urinary creatinine excretion (mg) was calculated as UCr (mg/dL) x urinary output in 2 h (dL). The measured 2-hours urinary creatinine (UCr) was reported to 24-hours UCr, and expressed as mg/24 hours.
Is 150 creatinine high?
According to the British Medical Journal, the usual reference range for serum creatinine is 60–110 micromoles per liter (mcmol/l), or 0.7–1.2 milligrams per deciliter (mg/dl), for males and 45–90 mcmol/l (0.5–1.0 mg/dl) for females. If creatinine is above these levels, doctors may consider it high.
What is normal creatinine for age?
Here are the normal values by age: 0.9 to 1.3 mg/dL for adult males. 0.6 to 1.1 mg/dL for adult females. 0.5 to 1.0 mg/dL for children ages 3 to 18 years.
What is normal creatinine clearance in elderly?
In adults younger than 50 years, daily creatinine clearance is 20-25 mg/kg ideal body weight in males and 15-20 mg/kg ideal body weight in females. In adults older than 50 years, daily creatinine clearance decreases progressively owing to reduction in muscle mass.
Does walking reduce creatinine?
Walking every day should be a very healthy form of exercise and should not change your serum creatinine in any way.
When to make an adjustment to the CrCL?
Some clinicians will make adjustments based on the actual weight of the patient in relation that patient’s ideal body weight (IBW) and/or adjusted body weight (ABW), especially if their actual body weight is greater than 20% over the IBW. Failing to consider the actual weight of the patient could also grossly overestimate the CrCl.
How does the CrCL calculator for blood work?
How does this CRCL calculator work? This is a health tool that aims to calculate the creatinine clearance through the Jelliffe equation that requires serum creatinine as provided through a blood test, age, gender, height and weight.
How to calculate the surface area of CrCl?
In case the serum creatinin is expressed in mg/dL, the conversion from mg/dL to µmol/L should be made by the following rate: 1 mg/dL = 88.4 µmol/L. Source: adapted from Oxford Journals. ■ Estimating body surface area by Boyd’s method:
