# Is serum creatinine the same as creatinine clearance?

## Is serum creatinine the same as creatinine clearance?

There is a difference between looking at creatinine in your bloodstream (called “serum creatinine”) and looking at creatinine in your urine (called “creatinine clearance”). These are two different lab tests. Serum creatinine is part of a routine lab report; creatinine clearance is not.

## How do you measure creatinine clearance?

To calculate creatinine clearance, the creatinine level in the urine is multiplied by the total volume of urine produced over 24 hours. This is then divided by the amount of creatinine in the blood. The final value is converted to milliliters of blood per minute (mL/min).

How do you calculate ideal creatinine clearance weight?

Cockcroft and Gault equation utilizing the ibw (Ideal body weight) to calculate an estimated creatinine clearance. actual body weight for calculating the CRCL. Males: IBW = 50 kg + 2.3 kg for each inch over 5 feet. Females: IBW = 45.5 kg + 2.3 kg for each inch over 5 feet.

### What is creatinine clearance normal value?

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).

### How do you calculate BSA?

According to Mosteller’s “simplified calculation of body-surface area In metric terms” the body surface area = the square root of product of the weight in kg times the height in cm divided by 3600.

What is a normal 24-hour creatinine clearance?

The normal range for a 24-hour urine creatinine level is 500-2000 mg/day.

#### What is the equation for creatinine clearance?

Cockcroft and Gault equation utilizing the ibw (Ideal body weight) to calculate an estimated creatinine clearance. Estimate Ideal body weight in (kg) Males: IBW = 50 kg + 2.3 kg for each inch over 5 feet. Females: IBW = 45.5 kg + 2.3 kg for each inch over 5 feet.

#### How do you calculate CrCL?

CRCL is calculated on the basis of a properly defined equation called Cockcroft-Gault Equation . To calculate CRCL, you need to use a dependable calculator designed for this purpose. CRCL is calculated on the basis of multiple input parameters including sex, weight, age and creatinine.

What weight to use CrCL?

Original Cockcroft-Gault equation: CrCl = (140−age)∗(weight in kg) ∗ (0.85, if female) 72*SCr. Over the next few decades, the original Cockcroft-Gault equation was modified to use ideal body weight (=2.3 kg*each inch over 5 feet + W; W= 50 kg for males; 45.5 kg for females).2.

## How to calculate serum creatinine?

Calculation information: This formula is applicable only if the serum creatinine is stable. Est. Creatinine Clearance = [[140 – age(yr)]*weight(kg)]/[72* serum Cr(mg/dL)] (multiply by 0.85 for women).
