Increase in Serum Creatinine

Creatinine usually enters your bloodstream and is filtered from the bloodstream at a generally constant rate. The amount of creatinine in your blood should be relatively stable. An increased level of creatinine may be a sign of poor kidney function.

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). The typical range for serum creatinine is:

• For adult men, 0.74 to 1.35 mg/dL (65.4 to 119.3 micromoles/L)
• For adult women, 0.59 to 1.04 mg/dL (52.2 to 91.9 micromoles/L)
