LW Scientific URS-10PR-7777 10-Parameter Urine Reagent Strips | 100/Vial

The LW Scientific URS-10PR-7777 is a 10-parameter urine reagent test strip for professional clinical urinalysis that delivers qualitative and semi-quantitative results for ten diagnostic analytes in a single 60-second dip. Manufactured by LW Scientific, Inc. — an ISO 13485-certified laboratory equipment company with over 30 years serving clinical, research, and healthcare markets — each sealed vial contains 100 individual single-use reagent strips with a color-coded reference chart printed directly on the label for immediate point-of-care visual comparison.

Parameters Tested

One strip. One dip. Ten clinically significant analytes covering renal function, metabolic status, liver health, and urinary tract infection indicators simultaneously:

Features & Benefits

• 10 analytes in 60 seconds — comprehensive one-dip urinalysis covering renal, metabolic, hepatic, and infectious disease indicators simultaneously, reducing per-test cost and workflow time
• On-vial color reference chart — printed directly on the label; no loose insert to misplace at the point of care
• Automated analyzer compatibility — compatible with the LW Scientific Accustrip URS Reader for objective quantitative results, eliminating subjective color comparison variability
• ISO 13485-certified manufacturing — produced under a certified quality management system for IVD devices, ensuring consistent lot-to-lot reagent performance
• Extended shelf life when sealed — desiccant-protected vials maintain reagent integrity for reliable supply management in lower-volume settings
• 100 strips per vial — standard clinical pack size with economical cost-per-test at scale
• Clinically tested for accuracy — validated performance across physician offices, urgent care networks, and reference laboratories

Specifications

Intended Use & Applications

For professional clinical use only in qualified laboratory and near-patient testing environments. Appropriate applications include:

• Routine urinalysis — physician offices, urgent care clinics, hospital laboratories, and reference labs
• Diabetic patient monitoring — simultaneous glucosuria and ketonuria screening in a single strip
• UTI screening — nitrite and leukocyte esterase together form a rapid combination indicator for suspected urinary tract infection; a negative nitrite with a positive leukocyte result warrants further culture
• Renal function assessment — protein, specific gravity, and blood together screen for glomerular and tubular dysfunction
• Liver disease differential — bilirubin and urobilinogen combination supports differential diagnosis of jaundice (hepatic vs. obstructive vs. hemolytic)
• Pre-operative and general health screening panels
• Occupational health and insurance medical examination panels

Usage Instructions

1. Collect a fresh urine specimen in a clean, dry container. Do not centrifuge. Test within 4 hours of voiding. First morning specimens provide highest analyte concentrations.
2. Remove one strip from the vial. Replace the cap immediately to protect remaining strips from moisture, heat, and light.
3. Briefly immerse all reagent pads fully in the urine sample, then remove immediately to prevent reagent pad dissolution.
4. Run the strip edge against the container rim to remove excess urine. Hold the strip horizontally to prevent cross-contamination between adjacent reagent pads.
5. Compare each pad color to the corresponding color block on the vial label at 60 seconds. Read the leukocyte pad within 120 seconds. Color changes occurring after 2 minutes are not diagnostically significant.
6. For automated reading: follow the LW Scientific Accustrip URS Reader operator manual instructions precisely.

Frequently Asked Questions

Is the URS-10PR-7777 approved for home use?

No. The LW Scientific 10-parameter strip is designated for professional clinical use only and must not be used as an at-home or over-the-counter test. For non-clinical ketone monitoring such as keto diet tracking, see the LW Scientific URS-01PR-KE77 single-parameter Ketone Strip.

Can these strips be used with an automated analyzer?

Yes. The URS-10PR-7777 is compatible with the LW Scientific Accustrip URS Reader, which provides automated, objective quantitative urinalysis results. Strips can also be read visually using the color reference chart printed on the vial label.

How does this compare to the 5-parameter strip?

The LW Scientific URS-05PR-7777 5-parameter strip tests Glucose, Protein, pH, Blood, and Ketone only — a focused metabolic and renal panel without liver function markers (Bilirubin, Urobilinogen) or UTI indicators (Nitrite, Leukocytes, Specific Gravity). Choose the URS-10PR-7777 when a complete urinalysis panel is clinically required.

What substances interfere with results?

High concentrations of ascorbic acid (vitamin C) can produce false-negative results for the glucose, bilirubin, nitrite, and blood pads. Alkaline urine (pH >8.0) from bacterial overgrowth can cause false-positive protein results. Urine-coloring medications such as phenazopyridine may affect bilirubin and urobilinogen pad readings. Clinically significant positive results should be confirmed with appropriate follow-up testing.

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 packet. Replace the cap immediately after removing each strip. Do not use strips after the expiration date printed on the vial label.
