The LW Scientific URS-05PR-7777 is a 5-parameter urine reagent test strip for professional clinical urinalysis, providing qualitative and semi-quantitative screening for five core diagnostic analytes — Glucose, Protein, pH, Blood, and Ketone — in a single 60-second dip. Manufactured by LW Scientific, Inc., an ISO 13485-certified laboratory equipment company, this focused-panel strip targets the most commonly ordered urinalysis parameters for metabolic, renal, and acid-base screening without the cost of a full 10-parameter panel. Each sealed vial contains 100 individual single-use reagent strips with a color-coded reference chart on the label.
Parameters Tested
| Parameter | Clinical Significance | Sensitivity / Detection Range |
|---|---|---|
| Glucose | Diabetes mellitus screening; renal glycosuria | Glucose oxidase-peroxidase reaction (enzyme-specific to glucose) |
| Protein | Renal disease, glomerulonephritis, proteinuria | Protein-error-of-indicators (tetrabromophenol blue) |
| pH | Acid-base balance; kidney stone risk; specimen quality indicator | pH 5–9 range (double-indicator colorimetric system) |
| Blood | Hematuria; renal, bladder, or urethral pathology | Hemoglobin peroxidase reaction (detects intact RBCs and free hemoglobin) |
| Ketone (Acetoacetic Acid) | Diabetic ketoacidosis; starvation ketosis; metabolic assessment | 10 mg/dL acetoacetic acid / 50 mg/dL acetone (sodium nitroprusside, alkaline medium) |
Features & Benefits
- Focused 5-parameter panel — covers the most frequently ordered urinalysis analytes for metabolic and renal screening; lower cost-per-test than full 10-parameter panels in workflows that address UTI and liver parameters separately
- Results in 60 seconds — rapid visual read directly from the on-vial color reference chart
- ISO 13485-certified manufacturing — consistent lot-to-lot quality under a certified IVD quality management system
- Accustrip URS Reader compatible — supports automated, objective quantitative reading, eliminating visual interpretation variability
- 100 strips per vial — standard clinical pack size with extended shelf life when sealed

Intended Use & Applications
For professional clinical use only. Appropriate settings and applications include:
- Diabetic patient follow-up — combined glucose and ketone screening in a single strip for efficient diabetes monitoring visits
- Renal monitoring — protein, blood, and pH screening for nephropathy and renal disease follow-up
- Obstetric urinalysis — glucose and protein are the two primary parameters monitored in prenatal urinalysis panels
- Cost-optimized urinalysis workflows — ideal where UTI indicators (nitrite, leukocytes) and liver function markers (bilirubin, urobilinogen) are assessed via separate or less frequent testing protocols
- High-throughput occupational health screening
Usage Instructions
- Collect a fresh urine specimen in a clean, dry container. Do not centrifuge. Test within 4 hours of voiding.
- Remove one strip. Replace the cap immediately to protect remaining strips.
- Briefly immerse all reagent pads fully in urine, then remove immediately.
- Run the strip edge against the container rim to remove excess urine. Hold horizontally to prevent cross-contamination between pads.
- Compare each pad color to the on-vial color chart at 60 seconds. Color changes after 2 minutes are not diagnostically significant.

Frequently Asked Questions
- What parameters are NOT included compared to the 10-parameter strip?
- The URS-05PR-7777 does not test for Bilirubin, Nitrite, Urobilinogen, Specific Gravity, or Leukocytes. For complete urinalysis including UTI indicators (nitrite and leukocytes) and liver function markers (bilirubin and urobilinogen), use the LW Scientific URS-10PR-7777 10-parameter strip.
- Is the URS-05PR-7777 suitable for home use?
- No. This strip is designated for professional clinical laboratory use only. For non-clinical ketone monitoring such as low-carb or keto diet tracking, see the LW Scientific URS-01PR-KE77 Ketone Strip.
- What substances can interfere with results?
- High concentrations of ascorbic acid (vitamin C) can produce false-negative results for the glucose and blood pads. Alkaline urine (pH >8.0) from bacterial overgrowth can cause false-positive protein results. Do not use formaldehyde as a urine preservative with these strips.
- How should strips be stored?
- Store in the original sealed vial at room temperature (59–86°F / 15–30°C), away from direct sunlight, heat, and humidity. Do not remove the desiccant. Replace the cap immediately after each use. Do not use after the expiration date printed on the vial.
