What is the main purpose of placing a drop of urine on each reagent pad of the dipstick?
What is the main purpose of placing a drop of urine on each reagent pad of the dipstick?
- To observe the color changes indicating the presence of substances. (correct)
- To ensure the dipstick is adequately saturated with urine.
- To mix the chemicals in the reagents for better accuracy.
- To prevent contamination of the urine sample.
Which of the following statements about handling dipsticks after testing is correct?
Which of the following statements about handling dipsticks after testing is correct?
- Anything contaminated with urine must be disposed of in a clinical waste bin. (correct)
- Wiping up spills does not require special precautions.
- Syringes used for real urine can be left out for later use.
- Used dipsticks can be disposed of in regular waste bins.
Why should only a drop of urine be placed on each reagent pad?
Why should only a drop of urine be placed on each reagent pad?
- The pads are designed only to absorb a small quantity.
- Excess urine causes the reagents to run and mix, affecting accuracy. (correct)
- Too much urine could cause overflow on the dipstick device.
- More than a drop could dilute the urine sample.

Reagent pad function
Reagent pad function
Reagent pads contain chemicals that react with specific substances in urine (like protein) to create a color change.
Urine dipstick procedure
Urine dipstick procedure
A method to test urine for various substances, such as protein. It involves placing a drop of urine on reagent pads and comparing color changes with standards.
Protein detection method
Protein detection method
The color change on a specific reagent pad indicates the presence of protein in the urine sample.

Study Notes
Equipment for Urinary System Station
- Urine dipsticks are required
- Real or substitute urine is needed
- A syringe is part of the equipment
- Paper towel or tissue is provided
- Gloves are essential
Considerations for the Station
- Gloves must be worn
- Contaminated materials (tissue, paper, etc.) with urine should be disposed of in clinical waste
- Substitute urine is acceptable in the Clinical Skills Lab
- Students must adhere to lab area rules
- Lab coats or scrub tops should be fastened correctly
- Any spills should be cleaned up and the work surface sprayed with 1% Virkon solution
- Hands should be washed in the hand wash sink with appropriate disinfection
Dipstick Tests - Principle
- Dipstick tests are quick, simple methods for detecting specific substances in urine
- A dipstick is a plastic strip with absorbent test pads
- The test pads are coated with reagents that react with substances in the urine sample (e.g., glucose, protein, ketones)
- Chemical reactions cause color changes in the pads
- Color intensity indicates the concentration of the substance
- The color changes are compared to a chart to determine the qualitative or quantitative assessment of the substances in the urine sample.
Dipstick Test Procedure
- Use a sterile syringe to collect urine samples
- Apply a drop of urine to each reagent pad on the strip
- Do not over-apply urine; it may mix reagents
- Compare colors to the standards on the dipstick packaging.
- Reading times are usually indicated on the packaging
- The right hand strip may indicate protein in the urine
Testing Parameters of Dipstick Reagents
- Specific gravity, pH, glucose, protein, blood, bilirubin, ketones, urobilinogen, nitrite, and leukocytes are usually tested for in urine
