Creat Clear		L/min L/sec mL/hr mL/min mL/sec
Decimal Precision   0 1 2 3

 

 

Notes

• In this calculator, mcg is the abbreviation for micrograms.
• This equation is a simple re-write of the standard formula: Clearance = UV/P
• The volume term V is actually best represented as V dot (for flow), with units of mL/min.
• The term UV is the mass of creatinine excreted in one day.
• The constant 0.0144 is a properly scaled version of the number of minutes in one day: 1440
