Title
(EN) METHOD OF DETERMINING RENAL CLEARANCES
(FR) METHODE DE DETERMINATION DES CLAIRANCES RENALES
Abstract
(EN)
In a method of determining creatinine clearance for detecting and monitoring renal dysfunction, spot samples of urine and blood from a person are obtained. Specific gravity or osmolality and creatinine concentration of the urine sample are measured. Creatinine concentration of plasma of the blood sample is also measured. Creatinine clearance is calculated as a function of the measured urine specific gravity or osmolality, the measured urine creatinine concentration and the measured plasma creatinine concentration.

Dans la méthode décrite, permettant de déterminer la clairance de créatinine en vue de détecter et de suivre les dysfonctionnements du rein, on recueille ponctuellement des échantillons d'urine et de sang chez un sujet. On mesure la densité ou l'osmolalité et la concentration en créatinine de l'urine prélevée. On mesure également la concentration en créatinine dans le plasma du sang prélevé. On calcule la clairance de créatinine en fonction de la densité ou de l'osmolalité de l'urine, de la concentration de créatinine mesurée dans l'urine et de la concentration de créatinine mesurée dans le plasma.
