Specimen Collection Urine

Specimen Collection Urine

Random
■ Indicated for routine screening and may be collected at any time.
■ Instruct Pt to void into the specimen container.

Clean Catch (midstream)
■ Indicated for microbiologic and cytologic studies.
■ Males:Wash hands thoroughly, cleanse the meatus, pull back foreskin, void a small amount into the toilet, then void into the specimen collection container. Secure lid tightly.
■ Females:Wash hands thoroughly, and cleanse the labia and meatus from front to back. While holding the labia apart, void a small amount into the toilet and then, without interrupting the flow of urine, void into the specimen collection container. Secure lid tightly.

Catheterized Random/Clean Catch
■ Ensure tubing is empty and then clamp the tube distal to the collection port for 15 minutes.
■ Cleanse collection port with an antiseptic swab and allow to air dry.
■ Using a needle and syringe, withdraw the required amount of specimen and then unclamp the tubing.
■ Follow laboratory guidelines for handling.

First Morning
■ Yields a very concentrated specimen for screening substances less detectible in a more dilute sample.
■ Instruct Pt to void into the specimen container upon awakening.

Second Void
■ Instruct Pt to void, drink a glass of water, wait 30 minutes, and then void into a specimen collection container.

Timed (24-hour urine)
■ Used to quantify substances in urine and to measure substances whose level of excretion varies over time.
■ Ideally, collection should begin between 6:00 a.m. and 8:00 a.m.
■ Specimen container should be refrigerated or kept on ice for the entire collection period.
■ The start time of the 24-hour collection begins with the collection and discard of the first void.
■ Instruct Pt to discard the first void of the day and record the date and time on the collection container.
■ Add each subsequent void to the collection container and instruct the Pt to void at the same time the following morning and add it to the collection container.
■ This is the end of the 24-hour collection period.
■ Record date and time and send the specimen to the lab.

Timed (24-hour urine) Catheterized Patients
■ Follows the same guidelines as a regular timed urine, but is started after the bag and tubing have been replaced. This is the start time and should be recorded on the collection container.
■ Either the collection bag is kept on ice, or the specimen is emptied every 2 hours into a collection container, which is refrigerated or kept on ice.
■ At the end of 24 hours, the remaining urine is emptied into the collection container.
■ This is the end of the 24-hour collection period.
■ Record date and time and send the specimen to the lab.
