HOW TO PROPERLY STORE REAGENT STRIps

urine protein analysis

protein error of indicators

• protein can alter the color of some acid-base indicators without changing the pH

Result

clinical significance

• Proteinuria - first indicator of renal disease

PROTEINURIA

• causes:
• increase in qty. of plasma proteins filtered
• reduced reabsorptive ability of renal tubules

URINE BLOOD ANALYISis

principle

• pseudoperoxidase action of hemoglobin and RBCs which catalyzes reaction of tetramethylbenzidine and buffered organic peroxide

Result

CLinical significance

• Hematuria
• Hemoglobinuria
