How long does it take for urine to go bad? It is a common question asked by patients who are collecting urine samples for medical testing. The answer depends on a number of factors, including the temperature and the presence of bacteria.
At room temperature, urine can typically be stored for up to 24 hours before it begins to break down. However, if the urine is refrigerated, it can be stored for up to 72 hours. If the urine is frozen, it can be stored for up to 6 months.
The presence of bacteria can also affect how long urine can be stored. Bacteria can cause urine to break down more quickly, so it is important to collect urine samples in a sterile container and to refrigerate them as soon as possible.
If you are collecting a urine sample for medical testing, it is important to follow the instructions provided by your doctor. This will ensure that the sample is collected and stored properly, and that the results of the test are accurate.
