Bu hasapçy hakda
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.
Köp soralýan soraglar
CKD-EPI deňleşik näme?
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.
GFR sanlar näme aňladýar?
eGFR 90 ýa-da has ýokary, başga alamatlar bolmadyk bolsa, normaldyr; 60-89 az azaldylandyr; 45-59 we 30-44 G3a we G3b tapgyrlar; 15-29 agyr (G4) we 15-den az bolsa böwrek ýetmezçiligidir (G5). G3-G5 tapgyrlar adatça lukman gözegçiligini talap edýär.
Bu böwrek keselini anyklamakmy?
Haýal. eGFR bir bahadyr, bu agyrsak kütlesinden, iýmitden we bir kreatinin okamakdan täsirlenip biler. Ýokary böwrek keselini bir kliniki, wagt içinde tekrarlanan testler bilen, iýmit we başga tapyndylar bilen anyklaýar.
Normal eGFR näme?
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.
Haçan eGFR 3-nji tapgyr böwrek keselini hasaplaýar?
G3a tapgyry 45-59 eGFR we G3b 30-44, filtrleme ukybynyň ortaça ýitgisini görkezýär. Bu tapgyrlar adatça kliniki tarapyndan gözegçilik we dolandyrmak üçin gerekdir.
Men ýaşym ýetende näme üçin deňleşik eGFR-i peseldir?
Filtrleme ýyllar içinde elbetde peselýär, şonuň üçin CKD-EPI ýaş terminini (0.9938 siziň ýaşyňyza çenli ýokarlan) öz içine alýar. Ösüşli bir adamda eGFR-iň az-azdan peselmegi elbetde böwrek keselini aňlatmaýar.
Serum kreatinin nädip ýokarlanýar ýa-da aşak gidýär?
Beýik agyrlyk, etli iýmitler we dehidrifikasiýa kreatininiň artmagyny we GFR-niň peslemesini getirýär, ýöne kiçi agyrlyk ony peseldir. eGFR bu bir bahadan ybarat bolansoň, ony dogry düşünmek üçin tekrar test gerek.
