What Is the Multistix 10 SG?
Multistix 10 SG is a diagnostic reagent strip used to perform semi-quantitative analysis of urinary components. It aids in the detection of various substances in urine, such as glucose, bilirubin, ketones, specific gravity, blood, pH, protein, urobilinogen, nitrite, and leukocytes. The package insert provides essential information for accurate testing and interpretation.
Purpose of the Package Insert
The primary purpose of the Multistix 10 SG package insert is to serve as a reference guide that details:
- Proper usage procedures
- Interpretation of test results
- Storage conditions
- Precautions and warnings
- Troubleshooting tips
This ensures that users can confidently perform urinalysis tests with reliable results, minimizing errors.

Usage Instructions from the Package Insert
Specimen Collection and Preparation
Accurate urinalysis begins with proper specimen collection:
- Collect a fresh midstream clean-catch urine sample.
- Avoid contamination with fecal matter or toilet water.
- Use the sample promptly, ideally within 2 hours; if delayed, refrigerate at 2-8°C.
Testing Procedure
The standard steps generally include:
1. Preparation: Remove the test strip from the vial, cap immediately, and avoid exposure to moisture.
2. Dipping: Immerse the strip vertically into the urine sample for the specified time (usually 1-2 seconds).
3. Removal: Remove excess urine by tapping the strip against the container's side.
4. Timing: Start a timer according to the manufacturer's recommendations.
5. Reading Results: Match the color change on each pad against the provided color chart within the specified time window.
Interpreting Results
Results are typically semi-quantitative, expressed as:
- Negative
- Trace
- Small
- Moderate
- Large
Color charts help translate the pad color changes into meaningful clinical data.
Analyzing Test Results Using the Package Insert
Understanding the Analytes
The insert details the significance of each parameter:
- Glucose: Elevated levels indicate hyperglycemia or diabetes.
- Bilirubin: Presence suggests liver disease or hemolysis.
- Ketones: Elevated in diabetic ketoacidosis, fasting, or low carbohydrate intake.
- Specific Gravity: Reflects urine concentration, indicating hydration status.
- Blood: Detects hematuria, which can be caused by infections, stones, or trauma.
- pH: Indicates acid-base balance; abnormal pH can suggest metabolic disturbances.
- Protein: Elevated levels may point to kidney disease.
- Urobilinogen: Increased levels can be linked to liver disease or hemolytic disorders.
- Nitrite: A positive result suggests bacterial infection.
- Leukocytes: Presence indicates pyuria, often associated with urinary tract infections.
Limitations and Interferences
The insert emphasizes that results can be affected by:
- Medications (e.g., certain antibiotics or vitamins)
- Contaminants
- Improper storage or handling
- Specific patient conditions
Understanding these limitations helps in accurate interpretation.
Storage and Stability Information
Storage Conditions
The package insert specifies:
- Store the reagent strips at 15-30°C (59-86°F)
- Keep container tightly closed to prevent moisture absorption
- Protect from direct sunlight and humidity
Expiration Date
It is critical to adhere to the expiration date printed on the package to ensure test accuracy. Expired strips may give false or unreliable results.
Handling Precautions
- Do not use if the vial is damaged or the cap is compromised.
- Avoid cross-contamination by using clean, dry hands.
- Dispose of used strips according to biomedical waste regulations.
Safety and Regulatory Considerations
Warnings
- For in vitro diagnostic use only.
- Do not ingest or inject.
- Avoid contact with skin and mucous membranes.
- Follow appropriate biosafety protocols when handling urine samples.
Regulatory Compliance
The insert often references compliance with standards such as:
- CLIA (Clinical Laboratory Improvement Amendments)
- ISO standards for in vitro diagnostic devices
Troubleshooting Common Issues from the Package Insert
Invalid or Unreadable Results
- Check expiration date.
- Ensure proper storage.
- Confirm that the test was performed within the specified time frame.
- Avoid exposure to moisture or light.
Unexpected Results
- Repeat testing with a new strip.
- Verify specimen collection procedures.
- Consider interfering substances or medications.
