Urea and creatinine concentration, the urea: creatinine ratio
This is the second of two articles that together aim to explore current understanding of the clinical value of measuring serum/plasma urea concentration. The main focus of the first article [1] was physiological topics, such as urea production and renal processing of urea. The causes of increased and reduced plasma/serum urea concentration were also discussed. The main focus of this second arti...
متن کاملUrea and creatinine excretion
Plasma urea and creatinine concentrations and urea and creatinine clearances and excretion were measured in a sample of 40 infants of 25*5-33 weeks' gestation, birth weight 720-2000 g, between the ages of 0 5 and 33 days. Creatinine excretion rate was between 60 and 120 gmol/kg/day in the first five postnatal weeks (mean 90.5) and was independent of sex or growth retardation. This can be used i...
متن کاملEvaluation of the effect of exercise on serum creatinine and urea nitrogen in hemodialysis patients
Introduction. Chronic renal failure is a progressive disease in which kidney function is impaired, so that the body can not metabolize and maintain fluid balance and electrolytes. Therefore, the present study investigated changes in serum creatinine and urea nitrogen in hemodialysis patients in response to exercise. Materials and Methods. The subjects of this study were dialysis patients who we...
متن کاملUrea, creatinine, and glucose determined in plasma and whole blood by a differential pH technique.
We report the conditions (buffer composition and enzyme activity) required for estimating three frequently determined analytes--urea, glucose, and creatinine--by use of an improved version of the differential pH apparatus previously described (Clin Chem 29: 80-85, 1983). For each analyte, we used only one specific enzyme, thus avoiding a chain of auxiliary and indicator reactions. The method re...
