Kuhusu kifaa hiki cha kupigia hesabu
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.
Maswali yaliyoulizwa mara nyingi
Je, ni njia gani ya kupima ugonjwa huo?
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.
Idadi ya GFR inamaanisha nini?
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.
Je, huo ni ugonjwa wa figo?
La. eGFR ni kadirio ambalo laweza kuathiriwa na wingi wa misuli, ulaji na hata kiwango kimoja cha chini cha kusoma. maradhi ya figo yenye kudumu hugunduliwa na daktari kwa kurudia - rudia majaribio ya baada ya muda pamoja na mkojo na magunduzi mengine.
Ni nini eGFR ya kawaida?
eGFR ya 90 au juu bila ishara nyingine za kuharibika figo ni jambo la kawaida. Mwanamume mwenye umri wa miaka 50 mwenye tumbo la nguruwe wa 1.0 mg/dL anatokea karibu 92, ambao ni saa ya G1.
Ni eGFR gani ambayo huhesabu kuwa maradhi ya figo 3?
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.
Kwa nini kadiri umri wangu unavyopungua kiwango cha damu kinachopitishwa kwa njia hiyo hupungua?
Filtration naturally declines over the years, so CKD-EPI includes an age term (0.9938 raised to your age). A modestly reduced eGFR in an older adult is not automatically kidney disease.
Ni nini hufanya umajimaji wa umajimaji ushuke?
Misuli mikubwa, milo ya nyama na maji mwilini huongeza kiwango cha catinine na kupunguza uzito wa GFR, na hivyo kupunguza uzito wa misuli ya chini hupunguza uzito huo.
