24 Hour Urine Collection Instructions
Patient Education
Please read this entire brochure before you begin
your urine collection
Introduction
The accurately timed urine collection you are about
to perform is a part of your care. Important health
decisions depend on it. The test is valid only if
the collection includes all the urine you pass in
a 24-hour period. The test will be inaccurate and
may have to be repeated if, for any reason, some of
the urine you pass during the 24-hour period is not
put into the collection container.
Your physician may have requested several urine
tests. If the tests require different preservatives,
you will need to collect urine in separate 24-hour
periods. You will be given container(s) for each 24-
hour urine collection.
Tell the laboratory worker or nurse if you are taking
an antihistamine (allergy or cold remedy).
Follow the dietary instructions checked below.
You do not need to follow any special dietary
instructions. You may follow your usual dietary
routine.

Preparing the container
Remove the cap from the container (figure 1).
Expand the container so you can pour urine into it
(figure 2). As more urine is added, the container
will expand further (figure 3).
Urinate at the start time, but do not save the
urine. (This urine was formed before your
collection period began and should not be part of
your collection.)
Collection instructions
Collect all the urine you pass for the next 24 hours.
Use a clean plastic, paper or glass container to
catch your urine each time. (Do not use a metal
container.) Put the urine into the collection
container each time you urinate.
If a preservative has been provided, add it to the
collection container after putting your first urine
specimen into the collection container. Note the
caution statement on the preservative. Do not
urinate directly into the collection container
because the preservative could splash on you
causing a burn.
Do not refrigerate the specimen unless instructed
otherwise.
To end the collection, urinate at the stop time. Put
the urine into the collection container. (This urine
was formed during your collection period and
should be part of your collection.) If you are doing
only one collection, proceed to step 4.
If you are doing an additional 24-hour urine
collection, repeat the “Recording start and stop
times” followed by the “Collection instruction.”
Record your start and stop times here and on the
identification tag attached to the collection
container.
Start: ______ day ______ a.m. / p.m.
Stop: ______ day ______ a.m. / p.m.
Recording start and stop times
For your information and for laboratory
documentation, record your start and stop times
below and on the identification tag attached to the
collection container. Stop time is 24 hours after the
start time (for example, start at 7:a.m. and day and
finish at 7:00 a.m. the next day).
On the day you finish your 24-hour urine collection,
take the collection container(s) and return
specimen to St. Clare Hospital & Health Services
laboratory, for measuring and processing.
If you have any questions, call St. Clare Collection
and Processing Laboratory at 608-356-1462.
