A GFR calculator estimates the glomerular filtration rate — how well the kidneys filter blood — from a serum creatinine test, age and sex. It uses the race-free 2021 CKD-EPI creatinine equation, reporting eGFR in mL/min/1.73 m² and the matching chronic kidney disease (CKD) stage from G1 to G5. This is an estimate for education only and does not replace testing or advice from a clinician.
The equation weighs creatinine against a sex-specific constant, then adjusts for age. For a 50-year-old man with a serum creatinine of 1.0 mg/dL, CKD-EPI returns an eGFR of about 92 mL/min/1.73 m², which is stage G1 — normal function. A woman with the same creatinine reads slightly differently because the equation uses a lower constant (0.7 versus 0.9) and a 1.012 sex factor. Enter creatinine in mg/dL or µmol/L and the tool converts.
The result maps to a CKD stage: 90+ is G1, 60–89 G2, 45–59 and 30–44 are G3a and G3b, 15–29 is G4 and below 15 is kidney failure (G5). Stages G3 and worse usually prompt medical follow-up. Because eGFR rests on a single creatinine value and is affected by muscle mass and diet, it is a screening estimate, not a diagnosis — confirm any concern with a clinician.

Chii chinonzi CKD-EPI equation?
It is the standard formula for estimating GFR from creatinine: eGFR = 142 × min(Scr/κ,1)^α × max(Scr/κ,1)^−1.200 × 0.9938^age × 1.012 (if female), where κ and α depend on sex. The 2021 version removed the race coefficient.
Chii chinonzi GFR?
A eGFR ye 90 kana pamusoro pasina zvimwe zviratidzo ndezvakajairika; 60-89 inoderera zvakakwana; 45-59 uye 30-44 ndezvipatara G3a neG3b; 15-29 ndezvipatara zvakaoma (G4) uye pasi pe15 ndezvipatara zvechiropa zvinokanganisa (G5).
Chii chinonzi chirwere chechiropa?
No. eGFR inoratidza huwandu hwemafuta muropa, kudya, uye kuongororwa kwecreatine. Kutapukira kwechiropa kunoongororwa nechiremba nekushandisa zvidzidzo zvakapetwa kakawanda, pamwe nekutarisa maziso, maziso, uye zvimwe zvinhu.
Chii chinonzi normal eGFR?
An eGFR of 90 or above with no other signs of kidney damage is considered normal. A 50-year-old man with a creatinine of 1.0 mg/dL comes out at about 92, which is stage G1.
Chii chinonzi eGFR chinokosha sechikamu che3 chechirwere chechiropa?
Nhengo dzeG3a dzinowana eGFR ye45-59 uye dzeG3b dzinowana 30-44, zvichiratidza kuti chirwere ichi chinokonzera kuora kwechiropa.
Nei equation ichideredza eGFR sezvandinokura?
Kuchenesa kunoderera zvakajairika nemakore, saka CKD-EPI inosanganisira nguva yezera (0.9938 yakakwira kusvika pazera rako).Kuderera kwakaderera kweeGFR mumunhu achiri mudiki hakureve kuti ane chirwere chechiropa.
Chii chinoita kuti serum creatinine iende pamusoro kana pasi?
Kukwira kwemuviri, kudya kwenyama nekudya kwemvura kunoita kuti muviri uwane mvura yakawanda, uye izvi zvinowedzera kuwedzera kwecreatinine uye kuderedza GFR. Kunyangwe muviri uchiwana mvura shoma, muviri unowana mvura shoma. Nekudaro, eGFR inotarisa pane imwe chete kukosha, uye kuongororwa kwekutanga kunoda kuitwa kuti uone kuti mhedzisiro yacho iri nani here kana kuti kwete.
