Dwar din il-kalkulatur
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.
Mistoqsijiet li jsiru ta' spiss
X’inhi l-ekwazzjoni CKD-EPI?
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.
X’ ifissru n- numri tal- GFR?
eGFR ta’ 90 jew aktar mingħajr sinjali oħra huwa normali; 60-89 huwa mnaqqas ħafif; 45-59 u 30-44 huma stadji G3a u G3b; 15-29 huwa sever (G4) u taħt 15 huwa insuffiċjenza renali (G5); l-istadji G3-G5 ġeneralment jeħtieġu segwitu mediku.
Dan huwa dijanjosi ta’ mard tal-kliewi?
Le. eGFR huwa stima li tista’ tiġi affettwata mill-massa tal-muskoli, id-dieta u qari wieħed tal-kreatinina. Il-marda kronika tal-kliewi tiġi dijanjostikata minn kliniku bl-użu ta’ testijiet ripetuti matul iż-żmien flimkien ma’ awrina u sejbiet oħra.
X’inhi eGFR normali?
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.
Liema eGFR jgħodd bħala mard tal-kliewi fi stadju 3?
L-istadju G3a huwa eGFR ta’ 45-59 u G3b huwa 30-44, li jirrifletti telf moderat tal-kapaċità ta’ filtrazzjoni.Dawn l-istadji normalment jitolbu monitoraġġ u ġestjoni minn kliniku.
Għaliex l-ekwazzjoni tnaqqas l-eGFR hekk kif insir akbar?
Filtrazzjoni tonqos b’mod naturali matul is-snin, għalhekk CKD-EPI jinkludi terminu ta’ età (0.9938 miżjud għall-età tiegħek).eGFR imnaqqas b’mod modest f’adult anzjan mhuwiex awtomatikament mard tal-kliewi.
X’ jagħmel kreatinina fis- serum tmur sa jew isfel?
Massa tal-muskoli ogħla, ikliet tqal tal-laħam u deidrazzjoni jżidu l-kreatinina u b’hekk inaqqsu l-GFR stmat, filwaqt li massa baxxa tal-muskoli tnaqqasha.Minħabba li l-eGFR jiddependi fuq dak il-valur uniku, hemm bżonn ta’ testijiet ripetuti biex jiġi interpretat kif suppost.
