Combi 9 URS Reagent strips for urinalysis

**Composition:**

Combi 9 URS reagent strips typically contain the following chemical pads, each designed to test for specific substances in urine:

1. **pH** - Indicator dye (e.g., bromothymol blue) to measure urine acidity or alkalinity.
2. **Protein** - Tetrabromophenol blue or similar dye to detect protein levels.
3. **Glucose** - Glucose oxidase and peroxidase for glucose detection.
4. **Ketones** - Nitroprusside for acetoacetic acid detection.
5. **Bilirubin** - Diazo reaction for bilirubin detection.
6. **Urobilinogen** - Ehrlich's reagent for urobilinogen detection.
7. **Nitrite** - Greiss reaction for nitrite detection.
8. **Leukocytes** - Esterase reaction for leukocyte esterase detection.
9. **Specific Gravity** - Reagent that changes color based on urine concentration.

**Dosage:**

• **Usage**: The Combi 9 URS reagent strips are typically used as a qualitative test. Each strip is dipped into a fresh urine sample for a few seconds, then removed and allowed to react for a specified time (usually 30-60 seconds) before comparing the color changes to a provided color chart.
• **Frequency**: The frequency of testing can vary based on clinical needs, but it is often performed during routine urinalysis or when specific conditions are suspected.

**Indications:**

Combi 9 URS reagent strips are indicated for:

1. **Routine Urinalysis**: To screen for various metabolic and systemic conditions.
2. **Diabetes Monitoring**: To detect glucose and ketones in patients with diabetes.
3. **Kidney Function Assessment**: To evaluate protein levels and specific gravity.
4. **Infection Detection**: To identify nitrites and leukocytes, which may indicate urinary tract infections (UTIs).
5. **Liver Function Evaluation**: To detect bilirubin and urobilinogen levels, which can indicate liver dysfunction or hemolysis.

**Note**: Always refer to the manufacturer's instructions for specific details regarding the use, interpretation, and limitations of the Combi 9 URS reagent strips.
