DefinitionA test that assesses urine odor.
How the test is performed
Collect a "clean-catch" (midstream) urine sample. To obtain a clean-catch sample, men or boys should wipe clean the head of the penis . Women or girls need to wash the area between the lips of the vagina with soapy water and rinse well. As you start to urinate, allow a small amount to fall into the toilet bowl (this clears the urethra of contaminants). Then, in a clean container, catch about 1 to 2 ounces of urine and remove the container from the urine stream. Give the container to the health care provider or assistant.
The urine is drained into a container for transport back to the health care provider. The specimen is then smelled in a laboratory or by the health care provider to determine its odor.
How to prepare for the testNo special preparation is necessary for this test, but if the collection is being taken from an infant, a couple of extra collection bags may be necessary.
