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.
Mafunso ofunsidwa nthawi zambiri
Kodi ndi chiyani chomwe chimachititsa kuti matenda a shuga awonjezeke?
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.
Kodi GFR ndi chiyani?
eGFR ya 90 kapena pamwambapa popanda zizindikiro zina ndi yoyenera; 60-89 ndi yotsika pang'ono; 45-59 ndi 30-44 ndi mfundo za G3a ndi G3b; 15-29 ndi yovuta (G4) ndipo pansi pa 15 ndi kulephera kwa magazi (G5).
Kodi izi ndi diagnosis ya matenda a machiritso?
Palibe. eGFR ndi chiwerengero chomwe chimakhudzana ndi masamu a minofu, chakudya ndi kuphunzira kwa creatinine. Kukalamba kwa matenda a machiritso amadziwika ndi wochita kafukufuku pogwiritsa ntchito kuyesa kobwereza nthawi zonse komanso m'mimba ndi zina.
Kodi ndi chiyani chofunikira kuti mudziwe za 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.
Kodi eGFR imawerengedwa bwanji ngati matenda a m’mimba a m’chigawo cha 3?
Mlingo G3a ndi eGFR ya 45-59 ndi G3b ndi 30-44, yomwe imasonyeza kuwonongeka kwamphamvu kwa kutulutsa.Maphunzirowa amadziwika kuti amachititsa kutsatira ndi kuyendetsa ndi wochita kafukufuku.
N’chifukwa chiyani equation imachepetsa eGFR pamene ndikula?
Kutulutsa kwamadzi kumachepa mosalekeza zaka zambiri, choncho CKD-EPI imaphatikizapo nthawi ya zaka (0.9938 yowonjezeredwa mpaka zaka zanu).Kuchepetsa kwa eGFR kwa munthu wamkulu sikungotanthauza kuti ali ndi matenda a m’mimba.
Kodi n’chiyani chimachititsa kuti serum creatinine ikhale yotsika kapena yotsika?
Kukula kwa minofu, chakudya cholemera kwambiri ndi dehydration zimawonjezera creatinine ndipo zimachepetsa kuchuluka kwa GFR, pomwe kukula kwa minofu kumachepetsa. Popeza eGFR imatengera mtengo wokha, kufufuzidwa kwatsopano kuyenera kuchitidwa kuti kufotokozedwe bwino.
