Kako se meri kreatininin u urinu? Dobija se računski iz nivoa kreatinina u krvi i nivoa u 24 časovnom urinu (biuret). Kreatinin služi kao korekcioni faktor. Tada se određuje sa drugim analitom, na primer proteinima, radi procene izlučivanja tog analita putem urina. Kada je glomerularna filtracija bubrega (GFB) snižena za više od 50%, kreatinin će […]
