Inulin and creatinine are commonly used to estimate glomerular filtration rate (GFR). Inulin is a polysaccharide that is freely filtered by the kidneys and not reabsorbed or secreted, making it an ideal marker for GFR. Creatinine, a waste product of muscle metabolism, is also used because it is produced at a relatively constant rate and is primarily eliminated by glomerular filtration.
