As shown in this figure, in early renal disease, substantial decline in GFR may lead to only a slight elevation in serum creatinine.

WebGFR can detect kidney disease in its earliest stages, when it is most treatable. GFR can also help figure out if you have a condition that causes decreased blood flow to the kidneys, such as heart failure, shock, or severe fluid loss (dehydration). WebDuring the 1-year follow-up, the glomerular filtration rate (GFR) decreased in two thirds of the patients and remained stable in the other third. In this latter group, the pretreatment GFR was higher, and the effective renal plasma flow had increased, whereas in the patients with a decreased GFR no renal vasodilation had occurred during lisinopril therapy.
