Urine is more concentrated in the morning, this is why it is best suited as a sample for urinary diseases. A day time sample may be used in diagnosing a urinary tract infection.
Starting at 10 p.m. the previous night, your child should not eat, he or she may drink up to 2 dl of water. For a reliable specimen, urine should be in the bladder for at least 4 hours. The sample is taken in the morning. If your child has to go to the toilet during the night, wait for at least 4 hours before taking the sample.
You may take the sample at home
You will be given instructions and a sample container and tubes from a nurse. (Picture 1)
It is important to wash properly
Girls:
– Wash your own hands thoroughly. (Picture 2)
– Spread the labia. Wash the outer genitals with running water or a wet paper towel wiping from front to back 4 times each time with new paper. Do not use soap. Dry with a paper towel wiping from front to back. Use a clean paper each time. (Pictures 3-5)
Boys:
– Wash your own hands thoroughly. (Picture 2)
– Draw back the foreskin. Wash the head of the penis with running water or a wet paper towel 4 times, each wipe with new paper. Do not use soap. Dry with a paper towel. (Pictures 3-5)
Avoid touching the inside of the container as bacteria from your hands may contaminate the sample.
A mid stream sample is best
To collect the sample first let the child pass some urine into the toilet then without breaking the urine stream collect the sample into the container, 2/3 full is enough. The rest of the urine may be passed into the toilet. (Pictures 6-8)
Give the container to the nurse. If you are at home follow the instructions in pictures 9 and 10.
Picture 9. Close the container and remove the label on the lid. On a table, press each test tube stopper first against the needle. The needle will pierce the top and the urine will flow into the tube. Fill all the tubes you have been given.
Picture 10. Turn the tubes up side down 4-5 times to mix the sample.
