WebRenal creatinine and inulin clearance decreases with aging have been demonstrated for decades. These functional changes in filtration are associated with changes in the glomerular structure in the kidney. Circulatory senescence decreases blood flow to the kidneys, which further reduces the efficiency of renal clearance. WebApr 13, 2024 · When the kidneys are functioning well, the proteins after filtration are reabsorbed and returned to the bloodstream. Creatinine is a result of muscle metabolism that forms at a steady rate in the urine. The protein creatinine ratio is obtained after doing both a urine creatinine and a random urine protein test.
