What is the reference range for Serum Creatinine?

The standard reference range for Serum Creatinine is Approximately 0.6–1.2 mg/dL in women, 0.7–1.3 mg/dL in men; varies by age, sex, and muscle mass.. Reference ranges vary by laboratory and assay platform — interpret in context of the issuing laboratory's stated range.

What does the Serum Creatinine test measure?

Serum Creatinine (Cr) is a clinical biomarker used in metabolic-diabetes assessment. Creatinine is a breakdown product of muscle creatine phosphate, released into the circulation at a relatively constant rate proportional to muscle mass and filtered freely at the glomerulus with minimal tubular reabsorption. It is measured in 6 laboratory tests on BiomarkersLabs.com.

Reference Range: Approximately 0.6–1.2 mg/dL in women, 0.7–1.3 mg/dL in men; varies by age, sex, and muscle mass.
Units: µmol/L, mg/dL
Measured In: 6 tests
Category: Metabolic

Functional medicine optimalOptimal creatinine depends on sex, age, and muscle mass; most CKD-EPI eGFR calculations target an eGFR above 90 mL/min/1.73 m², which typically corresponds to creatinine below 1.0–1.1 mg/dL in adults of average build.

What is Serum Creatinine?

Creatinine is a breakdown product of muscle creatine phosphate, released into the circulation at a relatively constant rate proportional to muscle mass and filtered freely at the glomerulus with minimal tubular reabsorption. Its plasma concentration inversely reflects glomerular filtration rate, making it the most widely used endogenous marker of kidney function, though it is insensitive to early GFR decline.

Why is Serum Creatinine measured?

Creatinine is the cornerstone of estimated GFR equations (CKD-EPI, MDRD) used to stage chronic kidney disease and to dose renally cleared drugs. Acute rises signal acute kidney injury; chronic elevation reflects chronic kidney disease. Creatinine is influenced by muscle mass, so lower values are normal in older adults, women, and those with low muscle mass, while bodybuilders and high-meat consumers may have values at the upper reference limit without renal impairment.
