Accurex Tri-Stix pH Test Strip

Accurex Tri-Stix pH Test Strip
Glucose test is based on a double sequential enzyme reaction: Glucose Oxidase converts urine Glucose to gluconic acid and hydrogen peroxide. Subsequently, Peroxidase converts hydrogen peroxide into water and nascent oxygen. The nascent oxygen liberates iodine from potassium iodide to produce colors ranging from green to brown depending on the - urine glucose concentration. The protien is based on the principle of protein-error-of indicator. At a constant pH the development of any green colour is due to the presence of protein. Colors change from yellow for Negative through yellow - green and green to greenish -blue for Positive reactions depending on the urine protein concentration. The pH is based on a double indicator principle that gives a broad range of colour covering the entire urinary pH range. Colours range from orange through yellow and green to blue depending on the pH of the urine.

Uses:
Accu-Stix is a test strip used for semi quantitative estimation of glucose protein and pH in urine sample.

Product Specifications and Features:

• Tristix is a test strip used for semi-quantitative estimation of glucose protein and pH in urine sample

• Tristix is a disposable, ready to use plastic strip on which are affixed 3 reagent areas for testing: Glucose, Protein and pH

• When dipped in urine sample the strip colour is read visually, within 30 sec., requiring no additional laboratory equipment for testing

• The Tristix test strips are packed in an air tight plastic bottle containing a dessicant

Directions For Use:

• Collect fresh, well-mixed, uncentrifuged urine in a clean and dry container

• Remove one strip at a time, from the bottle and replace cap immediately and tightly

• Dip the reagent areas into urine for 1 to 2 seconds, While removing the strip from the urine run the edge of the strip along the container's wall and tap to remove excess urine from the strip

• Hold the strip close to the colour chart provided on the label, and match carefully. The protein and pH results can be read immediately. The glucose results should be read at 30 seconds. The colour charts should be matched under good light (but not direct sunlight)

• Avoid touching the strip directly on the colour chart as this will result in soiling the chart

• Interpret the results if the colour obtained falls between two adjacent color blocks

• Colour changes that occur after 30 seconds are of no quantitative diagnostic value

Safety Information:

• Do not transfer the strips from its original bottle to any other bottle

• Do not remove the desiccant from bottle

• Replace cap immediately and tightly after removing the reagent strips to maintain reagent reactivity

• Tristix should be protected from moisture. This will prevent deterioration during storage

• Care must be taken not to touch the test reagent areas of unused strips

• All test reagent strips must be used within 6 months from the date of opening the bottle

• Working areas and specimen containers should be free of detergents and other contaminating substances

• Dip test areas in urine completely, but briefly (1-2 seconds) to avoid dissolving out the reagents from test area

• Read test results carefully at the time specified

• Tristix is for in vitro diagnostic use
