Aangaande hierdie sakrekenaar
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.
Dikwels gevra vrae
Wat is die CKD-EPI vergelyking?
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.
Wat beteken die GFR - getalle?
An eGFR of 90 or above with no other signs is normal; 60–89 is mildly reduced; 45–59 and 30–44 are stages G3a and G3b; 15–29 is severe (G4) and below 15 is kidney failure (G5). Stages G3–G5 usually need medical follow-up.
Is dit'n diagnose van niersiekte?
Nee. eGFR is'n skatting wat deur spiermassa, dieet en'n enkele kreintien - lees aangetas kan word.'n Klinikus gediagnoseer dat chroniese niersiekte met behulp van herhaalde toetse met verloop van tyd plus urine en ander bevindings gediagnoseer word.
Wat is'n normale IGFR?
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.
Watter IKFR is die stadium van 3 niersiekte?
Stage G3a is an eGFR of 45–59 and G3b is 30–44, reflecting a moderate loss of filtering capacity. These stages usually prompt monitoring and management by a clinician.
Waarom is die vergelyking laer as ek ouer word?
Fiksrasie neem natuurlik oor die jare af, en CKD-EPI sluit dus 'n ouderdomsterm in (0.9938 wat tot jou ouderdom verhef is). 'n Beskeie verminderde GFR in 'n ouer volwassene is nie outomaties niersiekte nie.
Wat maak serumkreinien of af?
Hoër spiermassa, vleis-heavy maaltye en ontwatering verhoog kreinien en so verlaag die geskatte GFR, terwyl lae spiermassa dit verlaag. Aangesien eGFR skarniere op daardie enkele waarde, moet 'n mens herhaaldelik toets om dit behoorlik te vertolk.
