Test Overview
Colorimetic Rate
Evaluation of renal function
1-4 years: 0.2 - 0.6 mg/dL, 5-11 years: 0.4 - 0.9 mg/dL, 12-150 years, male: 0.7 - 1.3 mg/dL, female: 0.5 - 1.0 mg/dL. Estimated Glomerular Filtration Rates (eGFR) for both an African American and a non-African American individual calculated using the MDRD study equation will be reported with serum creatinine levels ordered alone or as part of a panel for patients aged 18 - 100 years. A GFR estimate between 15 and 59 mL/min for >= 3 months is classified as chronic kidney disease (Stage 3 or 4).
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
