WebJul 1, 2024 · The main difference between GFR and eGFR is that GFR or glomerular filtration rate describes the flow rate of the filtered fluid through kidney whereas eGFR or the estimated glomerular filtration rate is a number that estimates GFR. Furthermore, GFR can be measured by plasma or urinary clearance of an ideal filtration marker such as insulin, … WebThe creatinine clearance (CrCl) is used to estimate the glomerular filtration rate (GFR). It’s hard to directly measure the GFR, so we use CrCl –something we can measure–to estimate the GFR. Creatinine is derived from the metabolism of creatine in skeletal muscle and from dietary meat.

Kreatinin entsteht im Muskelgewebe durch den Abbau von Kreatin. Die Plasmakonzentration von Kreatinin unterliegt meistens nur geringen Schwankungen; sie ist jedoch abhängig von der Muskelaktivität und ist zum Beispiel bei hoher Querschnittslähmung deutlich reduziert. Kreatinin wird in idealisierter Betrachtung frei im Nierenkörperchen filtriert und durch die Nierenkanälchen weder rückresorbiert noch sezerniert.
