eGFR (estimated glomerular filtration rate)

Measured in mL/min/1.73m² · LOINC 62238-1

Reference ranges

Optimal

90 – 120 mL/min/1.73m²

functional-medicine target

Standard

60 – 120 mL/min/1.73m²

lab reference range

Optimal ranges are tighter than standard lab ranges and reflect functional-medicine targets, not the populations they were derived from. Reference bands depend on sex, age, and circumstance — Juno's lab analysis layers your profile context onto the printed range when you paste a value.

Peptide relevance

Derived from creatinine + age + sex + (historically race, now removed in CKD-EPI 2021); <60 sustained over 3+ months defines chronic kidney disease. NO direct peptide effects in common stacks but the eGFR formula's creatinine-dependency means heavily muscled users can show artificially LOW eGFR even with normal kidney function. Modern formulas (CKD-EPI 2021) drop the race coefficient. Cystatin C-based eGFR is the muscle-mass-independent alternative when creatinine-based eGFR is questionable. Order eGFR alongside creatinine routinely — the derivation is automatic at any modern lab.
