Hello, and thanks for your medical question on E Health Forum.

Measuring serum creatinine is a simple test and it is the most commonly used indicator of renal function. More important than absolute creatinine level is the trend of serum creatinine levels over time.

Serum creatinine is typically reported in mg/dL, In some cases it can be reported in μmol/litre may be used. 1 mg/dL of creatinine is 88.4 μmol/L.

The typical human reference ranges for serum creatinine are:
For women 0.5 to 1.0 mg/dL (about 45-90 μmol/L) and
In case of men 0.7 to 1.2 mg/dL (60-110 μmol/L) for men

Based on this information, your reports must have been reported in μmol/L . So those levels would be normal for a female , but slightly lower for a male.
Low creatinine levels could be due to overhydration (drinking excess of water).

In case of any doubts you can consult the laboratory or your treating doctor.

I hope you find the information here helpful.
