What parameters are used to determine kidney function in CKD patients?
Changes in kidney function are important outcomes in clinical trials assessing the effects of various BP-management regimens in CKD patients. Kidney function is usually based on parameters such as albumin/creatinine ratio (ACR), protein/creatinine ratio (PCR), albumin excretion rate (AER), and protein excretion rate (PER). Other important markers for kidney function include changes in glomerular filtration rate (GFR) or the percentage of patients in whom the serum creatinine (SCr) level doubles.
