eGFR (Kidney)

eGFR (estimated glomerular filtration rate) is a calculated estimate that clinicians interpret with the source measurement, reporting method, history, and other findings.

SomaZeus display band

For care decisions, use the interval printed by the reporting lab and ask your clinician. Labs, assay methods, and individual context vary; the numbers below are SomaZeus display guidance.

Watch points

  • Watch point 1: at or below 30 mL/min
  • Watch point 2: at or below 60 mL/min

SomaZeus uses the same watch points for men and women in this display.

Why hard-training athletes watch it

Muscle mass and other individual factors may affect a creatinine-based estimate. That context can help a clinician interpret the result but cannot show whether the estimate is accurate by itself.

When to retest

Ask your clinician whether and when a repeat or another kidney-function measure is appropriate for your context.

Talk to your clinician

Review eGFR with your clinician alongside creatinine, symptoms, history, prior results, the calculation method, and reporting lab interval.
