Accurex Tri-Stix pH Test Strip

Overview Accurex Tri-Stix pH Test Strip

Accu-TriStix urine test strips employ a three-part reagent system for semi-quantitative analysis of glucose, protein, and pH. Glucose detection utilizes a dual enzyme reaction: glucose oxidase converts glucose to gluconic acid and hydrogen peroxide, then peroxidase transforms hydrogen peroxide into water and nascent oxygen, liberating iodine from potassium iodide to create a color gradient (green to brown) correlating with glucose concentration. Protein assessment is based on a protein-error indicator principle, generating a color change (yellow to greenish-blue) reflecting protein levels at a constant pH. pH determination uses a dual-indicator system, yielding a broad color spectrum (orange to blue) across the urinary pH range. Accu-TriStix are single-use, plastic strips with three distinct reagent zones. After briefly immersing the strip in a fresh, uncentrifuged urine sample, visual color comparison with the provided chart, within 30 seconds for glucose and immediately for protein and pH, determines the analyte concentration under adequate lighting. The strips are packaged in an airtight container with a desiccant to ensure reagent stability. **Instructions:** Obtain a clean, dry urine sample. Remove a single strip, immediately resealing the container. Dip the strip into the urine (1-2 seconds), removing excess fluid. Compare the resulting color to the chart, interpreting results based on color block matches. Readings beyond 30 seconds (glucose) are invalid. Avoid touching the chart. **Precautions:** Use only the original container; do not remove the desiccant. Keep the container tightly closed to prevent moisture damage. Handle strips carefully, avoiding reagent area contact. Discard strips six months post-opening. Maintain a clean testing environment, free of contaminants. Ensure complete, but brief, reagent immersion. Accu-TriStix are for in-vitro diagnostic use only.

How to Use Accurex Tri-Stix pH Test Strip:

Obtain a clean, dry container and collect a fresh, thoroughly mixed urine sample without centrifugation. Remove one test strip at a time from the vial, immediately and securely replacing the cap. Briefly immerse the reagent area in the urine for one to two seconds; gently wipe the strip's edge against the container to remove excess urine. Compare the strip's color to the reference chart on the product label under ample, indirect light. Protein and pH levels are immediately discernible. Glucose results should be read after 30 seconds. Avoid direct contact between the strip and the color chart to prevent contamination. If the color falls between two chart blocks, interpret the result accordingly. Color changes observed beyond 30 seconds are not clinically significant.

Safety Instruction of Accurex Tri-Stix pH Test Strip:

• Keep the test strips in their original container.
• Keep the desiccant inside the container.
• Secure the container's lid firmly after removing the test strips to preserve the reagent's effectiveness.
• Keep Tristix dry to maintain its quality throughout storage.
• Avoid contact with the reagent zones on any unused test strips.
• Reagent strips should be discarded six months after initial container access.
• Surfaces and sample receptacles must be clean and free from detergents or other contaminants.
• Submerge the test zones in urine fully, yet for only a short duration (one to two seconds), to prevent the reagents from leaching out.
• Review the test findings as directed.
• Tristix is intended for laboratory diagnostic applications.
