What does the Creatinine (Urine) test measure?

Why is Creatinine (Urine) measured?

Creatinine serves as the denominator for all neurotransmitter and cortisol results in this profile. Very low or very high creatinine values may indicate dilute or concentrated specimens, respectively, prompting recollection if outside acceptable limits.

Reference ranges

Standard reference

50–250 mg/dL in random urine.

Functional medicine optimal

Creatinine should fall within the laboratory's acceptable range for normalisation; outliers may invalidate the creatinine-adjusted results.

Units

mg/dL

Reference ranges vary by laboratory and assay platform. Interpret in context of the issuing laboratory's stated range.
