I-GFR Calculator (eGFR, CKD-EPI)
Ukubalwa kwemisebenzi yenhliziyo (eGFR) kusuka ku-creatinine, ubudala nosuku, ngesigaba se-CKD.
Iziphetho zivuselelwa uma ubhala.
Malunga nale khadi
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.
Imibuzo ebuzwa kaningi
Yini i-CKD-EPI equation?
I-formula ejwayelekile yokulinganisa i-GFR kusuka ku-creatinine: eGFR = 142 × min(Scr/κ,1)^α × max(Scr/κ,1)^−1.200 × 0.9938^age × 1.012 (uma indoda), lapho i-κ ne-α ixhomekeka ekukhuleni. Uhlobo lwe-2021 lwasusa i-race coefficient.
Yini okusho ama-GFR?
I-eGFR engu-90 noma ngaphezulu ngaphandle kwamanye amazimpawu ijwayelekile; 60-89 iphansi kakhulu; 45-59 ne-30-44 yimikhawulo ye-G3a ne-G3b; 15-29 inzima (G4) futhi ngezansi kuka-15 isifo sofuba (G5). Imikhawulo ye-G3-G5 idinga ukunakekelwa kwezokwelapha.
Ingabe lokhu kukhombisa ukuthi unesifo senhliziyo?
Akunalutho. i-eGFR iyisilinganiso esithintana nesisindo samathambo, ukudla kanye nokufunda kwe-creatinine. Ukugula kwebele okuqhubekayo kuhlolwa ngumtholampilo ngokuphinda ukuhlolwa isikhathi eside kanye nokudla kanye nezinye izimpendulo.
Yini i-eGFR ejwayelekile?
I-eGFR engu-90 noma ngaphezulu ngaphandle kwamanye amacala okulahleka kwe-kidney ithathwa njengejwayelekile. Umfana oneminyaka engu-50 ubudala one-creatinine engu-1.0 mg/dL uphuma eneminyaka engu-92, okuyisigaba se-G1.
Yini i-eGFR ebhekwa njengesigaba 3 sokugula kwenhliziyo?
Isigaba G3a siyi-eGFR engu-45-59 futhi isigaba G3b siyi-30-44, okukhombisa ukulahleka okuncane kokusebenza kokuhluza. Lezi sigaba zivame ukuqondiswa nokulawulwa ngumhlinzeki wezokwelapha.
Kungani i-equation ikhuphula i-eGFR uma ngikhula?
Ukulungiswa kwegazi kuhla kakhulu eminyakeni edlule, ngakho i-CKD-EPI ifaka phakathi isigaba sobudala (0.9938 esikhuphuke kubudala bakho). I-eGFR ephansi kakhulu emuntu oneminyaka engaphezu kwengu-60 ayiyona isifo senhliziyo.
Yini eyenza i-creatinine ye-serum ikhuphuke noma ikhuphuke?
Ukudla okuningi kwamathambo, ukudla okunzima kanye nokukhuluphala kwenza ukuba khona kwe-creatinine kukhuphuke futhi kunciphise i-GFR elinganiselwe, kanti ukudla okuncane kwamathambo kwenza kube phansi. Ngokuba i-eGFR ihamba ngexabiso elilodwa, kuhlolwa okuphindiwe kudingeka ukuchaza kahle.
