What is this Fluid?? • High levels of Urea and Creatininelevels in Urine will help ID as urine. • Page 31 • Urine is 95% water and 5% Solutes • Urea accounts for nearly ½ of dissolved solids and other substances are mainly creatinine and Uric acid
Specific Gravity • Hypostenuric< 1.010 • Isostenuric1.010 Glomerular filtrate (lost ability to concentrate or dilute urine) • Hyperstenuric>1.010 • Osmolarity also used for similar information • Change of pKa w indicator • pH < 6.5 decrease Radiographic dye Increase
Hemosiderin • Hemoglobin in the urine may be reabsorbed by the renal tubular cells and appear as large yellow-brown granules • Stain with Prussian Blue • Transfusion reactions, Hemolytic anemia Severe burns, ect Associated with Hemoglobinuria
