EXPERIMENT 2: URINE PH A simple urinalysis can determine the pH of fluid wastes from the body. Testing the pH of urine elucidates the processes the body is utilizing to remove acid from the body and may point to system failures.

PROCEDURE 1. Allow the participant to go to the restroom to deposit a urine specimen into the specimen cup.

Note: The best sample is taken immediately after waking up in the morning.

2. Wash and dry your hands to prevent cross-contamination. Then, put on your gloves.

3. Completely immerse the test strip into the urine sample for approximately 5 seconds.

4. Remove the test strip. While removing the strip, touch the side of the strip against the rim of the specimen cup to remove excess urine.

5. Blot the strip lengthwise against an absorbent paper towel.

6. Compare the color results on your test strip to the color chart. Be sure to wait the appropriate, respective amount of time for the results to occur per test. Indicate your results for each test in the Results .
