2. Clean the genital area.
3. Start urinating into the toilet, pause, then move the collection container into the urine stream without touching the inside of the container.
4. Once the appropriate amount is collected, move the container out of the urine stream, tightly close it, and you can finish urinating in the toilet.
. Deliver the sample to the lab immediately after collection.
If delayed, store the sample in a cool place or refrigerate it (up to 2 hours) until submission.
