Blood tests are also used to assess kidney function. These include tests that are intended to directly measure the function of the kidneys, as well as tests that assess the function of the kidneys by looking for evidence of problems associated with abnormal function. One of the measures of kidney function is the glomerular filtration rate (GFR). Other tests that can assess the function of the kidneys include assessment of electrolyte levels such as potassium and phosphate, … WebResidual renal function is associated with improved survival and quality of life for dialysis patients. Whereas residual renal function is monitored in peritoneal dialysis patients, many hemodialysis centers simply concentrate on achieving dialyzer urea clearance targets.
