Patient Specimen Collection
For a standard urine collection, begin to urinate as usual and then put
the cup into the stream to catch some of the urine in the paper cup. It doesn't
take too much---about one-fourth of a cup will fill the tube--so you can finish
your business in the toilet. Bring your sample back to the unit for testing.
Test the sample in the fresh state.
- Mix: Give the sample a healthy swirl for several
seconds or mix the container by inversion several times before testing.
- Dip and drain: Dip the stick completely but briefly and
remove the strip by dragging the back of the strip across the mouth of the
container. This technique will drain off the excess urine. You can blot
the strip by pressing the side to a paper towel. Do not blot the strip on
- Time: In general, all pads may be read at 60
seconds-except for urobilinogen (10-30) seconds
and leukocytes (60-120 seconds). The optimum times are given below:
- pH may be read immediately
- glucose and ketone - wait 60 seconds after dipping
- urobilinogen - read 10-30 seconds after
- protein - read 30-60 seconds after dipping
- leukocytes - 60-120 seconds
- Color interpretation: Hold the strip against the guide
on the side of the container to compare the color and interpret the
- Close the container - tightly: The strips are stable
only if stored properly.
- Record the results: Write your name, the date and time
and the findings on the patient record in EPIC.
- Maintain the proper storage conditions by keeping the
reagents strips tightly covered and shielded from light. Always keep the
strips in the original container with the dessicant
- Do not use strips that are expired or are in suspect
conditions due to storage conditions.
- Follow the procedural instructions exactly. The strips
are designed to test urine. Do not use the strips on other samples.
- The laboratory assesses the quality to the reagent
strips on an ongoing basis. External quality control at the unit level is
not necessary for this test.
