The range of scores below 60 may be used to monitor treatment and disease progression. A GFR score below 60 suggests kidney disease. The formula for calculating GFR takes into account the serum creatinine count and other factors, such as age and sex. Because of variability in serum creatinine from one person to another, the GFR may provide a more accurate reading on kidney function. The measure of serum creatinine may also be used to estimate how quickly the kidneys filter blood (glomerular filtration rate). The typical range for serum creatinine is: Serum creatinine is reported as milligrams of creatinine to a deciliter of blood (mg/dL) or micromoles of creatinine to a liter of blood (micromoles/L).
