How do I explain this procedure to a male?
“I need you to collect some urine in this sample container. Do not touch the inside of the container. Start by washing your hands with soap and water. Use a wet swab to clean the head of your penis and under your foreskin if you are not circumcised. Next, start to pee into the toilet. After a second, put the container under the stream and catch urine until it is halfway full. Remove the container and finish peeing into the toilet. Wash your hands afterwards.”
How do I explain this procedure to a female?
“I need you to collect some urine in this sample container. Do not touch the inside of the container. Start by washing your hands with soap and water. Use a wet swab to clean your private parts. Next, start to pee into the toilet, holding the lips of your vulva open. After a second, put the container under the stream and catch urine until it is halfway full. Remove the container and finish peeing into the toilet. Wash your hands afterwards.”
Troubleshooting
My patient is unable to produce any urine.
Ask the patient to drink two to three cups of water and sit in the waiting room until they need to urinate.
Risks
Poor technique and specimen contamination
Fall risk if patient is unsteady
