Routine urinalysis is one of the common tests performed in the laboratory. Hence, it is crucial that even you, as the patient, learn the precautions in collecting your urine specimen for routine urinalysis.

Here are important precautions that you should observe.
Know if the test is, indeed, routine urinalysis.
There are other tests done on urine samples such as:
- Creatinine clearance
- 24-hr urine test
- 12-hr urine test
Once you are sure that it is routine urinalysis, you can now request for a sterile urine or sample container from the lab aide or technologist. If the doctor ordered the test, then wait for the sterile specimen container from the lab aide.
The best sample for routine urinalysis is the early morning urine sample.
After you wake up, collect your specimen in your container by washing your vagina properly first. The early morning urine is best because it contains more sediments than other samples.
Do the midstream catch method.
After washing, you then discard the first portion of your urine, and then collect the midstream part. This would prevent contamination from foreign or outside sources.
Open only the specimen container when you are ready to collect your urine.
Just like precaution no. 3, this would prevent contamination of your urine sample from foreign sources. You have to cover your sample immediately to prevent contamination.
Preserve the integrity of your urine sample by preserving it properly.
The sediments in urine specimens could disintegrate or be destroyed if you do not preserve your specimen. You can do this by submitting your specimen immediately to the laboratory.
If this is not possible, then you should preserve your urine specimen by storing it at refrigerated temperatures. Your specimen should reach the laboratory within an hour. This is one of the major precautions in specimen collection for routine urinalysis.
If you have menstruation, you should ensure that you have washed well, and that no blood has contaminated your sample.
You have to inform the medical technologist that you are menstruating. This would make him/her aware of the circumstances surrounding your urine collection.
Label your specimen bottle with your complete name
Remember to label your specimen bottle correctly with your complete name, including your middle initials. You can do this using a pentel pen or a masking tape. The lab aide would label it as soon as you submit your sample but it would help a lot if you label the sample too.
Observing these precautions in the specimen collection for routine urinalysis would ensure accurate results obtained from your specimen.
