A typical reference range is 60.0 – 120 mL/min/1.73m2. At TestWell it's $23.99 all-in as Renal Panel, results in 2–4 business days, drawn at Quest or Labcorp. An out-of-range result is a prompt to look closer, not a diagnosis.

An estimate of how much blood your kidneys filter per minute, calculated from creatinine. ## What is the normal range for eGFR? | Population | Reference range | | --- | --- | | age 18+ | 60.0 – 120 mL/min/1.73m2 | Reference intervals differ slightly between labs; the range printed on your report is the one to interpret against. Ranges are usually set so 95% of healthy people fall inside them. ## What does a low eGFR mean? Sustained values below 60 can indicate chronic kidney disease and warrant follow-up. ## How often should you retest? KDIGO recommends measuring eGFR (alongside urine albumin) at least once a year in people with chronic kidney disease, and more often at more advanced stages or higher risk — as frequently as every 1–3 months. Adults with diabetes or high blood pressure are generally checked yearly even with normal kidney function. ## How do you get tested for eGFR? | Order | Type | Price | Includes | | --- | --- | --- | --- | | [Renal Panel](https://www.test-well.com/tests/renal-panel) | Single test | $23.99 | This marker | | [Kidney Health Panel](https://www.test-well.com/tests/kidney-health-panel) | Panel | $64.99 | 4 tests | | [Total Body Panel](https://www.test-well.com/tests/total-body-panel) | Panel | $499.99 | 49 tests | ## Quest vs Labcorp vs BioReference | Lab | Available | Price | Notes | | --- | --- | --- | --- | | Quest Diagnostics | Yes | $23.99 | Choose Quest at checkout; walk-in patient service centers in every state TestWell serves outside NY and NJ. | | Labcorp | Yes | $23.99 | Choose Labcorp at checkout; walk-in patient service centers in every state TestWell serves outside NY and NJ. | | BioReference (NY & NJ) | No | — | Not available in NY/NJ for this test. | - [What a low eGFR means (causes, symptoms, next steps)](https://www.test-well.com/biomarkers/egfr/low) ## Common questions about eGFR ### Do I need a doctor's order to test my egfr?
