1. -This guide instructs the methods, reaction principles and points for attention for the use of Uritest Reagent Strips.

   • ´-Reagent Strips are the primary testing product for the diseases of abnormal kidney diabetes, damage of kidney,serious infection and abnormal liver function.
     • -The results on the strips can be read visually and instrumentally.
       • -You are required to read the User’s Guide before taking use of the strips.
   • General Summary

2. Visual Reading Technique

   • 1. Promptly replace cap after taking out strip
     • 2. Immerse the reagent area of the strip in the urine specimen and take it up quickly and immediately
       • 3. Run the edge of the strip against the rim of the container to remove the excess urine
         • 4.Hold the strip up horizontally and compare the result on the strip with the colour chart on the bottle label closely. Make note of the result.
           • 5.For a qualitative result, the strip should be read between 1-2 minutes after dipping.

3. Instrumental Reading Technique

   • Never use the products after the expiration date. Every strip can be used only once. Do not
   • Don’t take the strips from the bottle unless it is for immediate use. Cap the bottle immediately and tightly after taking out the strips.
   • The strips should be stored in a dry place at a temperature between 2° c -30° c’. Don’t store the strips in a refrigerator

4. Reaction Principles

   • Glucose: The glucose oxidized by glucose oxidase catalyzes the formation of glucuronic acid and peroxide hydrogen.
   • Bilirubin: The direct bilirubin and dichlorobenzene diazonium produce azo dyes in a strongly acid medium.
   • Ketone :The reagent strip reacts with acetoacetic acid in urine. False positive results may occur in highly pigmented urine or those containing a large amount of levodopa metabolites.
   • pH El área de prueba de pH mide los valores de pH en el rango de 5.0-9.0 instrumentalmente y 5.0-8.5 visualmente.
   • The reagent strips can detect urobilinogen in low amount as 3 µ mol/L (approximately 0. 2 Ehrlich unit/dL) in urine.
