How It Feels
Collecting a urine sample does not cause
There is no chance for problems while collecting
a urine sample.
A urine culture is a test to detect and
identify organisms (usually bacteria) that may be causing a
urinary tract infection (UTI). Urine culture results
are usually ready in 1 to 3 days. Some organisms take longer to grow in the
culture; for this reason, results may not be available for several days.
No bacteria or other organisms (such as
fungi) grow in the culture. The culture result is

count of 100,000 or more bacteria per
milliliter (mL) of urine may be caused by an
infection. A count ranging from 100 to 100,000 could be either caused by
infection or by contamination of the sample (you may need a repeat urine
culture). If the count is 100 or less, infection is unlikely; however, a count
of 100 or less may also be seen if you are already taking
If test results are positive,
sensitivity testing may be done to help make decisions
What Affects the Test
Reasons you may not be able to
have the test or why the results may not be helpful include:
- Taking antibiotics or just finished taking
- Taking water pills (diuretics) or
drinking a large amount of liquid. This may dilute your urine and reduce the
number of bacteria in the sample.
- Taking a lot of vitamin C.
