What is the normal creatinine clearance (CrCl) in women under age 40?

The normal creatinine clearance (CrCl) in women under age 40 typically falls within the range of 87 to 107 mL/min. This range is established based on standardized measurements and reflects the efficiency of the kidneys in filtering creatinine from the blood, which is an important indicator of renal function.

Creatinine clearance values in this range are considered normal for younger women, as they generally have better renal function compared to older adults, and physiological changes with age can lead to decreased clearance rates. The values derived from the Cockcroft-Gault equation, which accounts for factors such as age, gender, weight, and serum creatinine levels, help in estimating kidney function effectively.

Understanding these normal ranges is particularly vital in clinical practice to assess renal health, adjust medication dosages, and detect potential renal impairment early in younger populations.
