Urine Collection Instructions
When you wake up on the morning of the home visit, please collect your FIRST URINE of the day. To
help you remember to do this, place the urine cup next to the toilet the night before the visit.
•

If you work at night, please see the special instructions below

•

If you are a woman and are having your menstrual period, do not worry if blood gets in the cup.

•

If you get up in the middle of the night to urinate, please do not collect that urine. We want urine
collected when you “normally” wake up.

•

If possible, please remember to fast for at least 8 hours before the home visit. By fast, we mean
do not eat or drink anything except water in the 8 hours before your visit.

When you collect your urine:
1. Fill to the 90 mark with urine and screw the lid securely on the cup.
2. Write the date and time you collected your urine on the paper label on the side of the
cup. DO NOT WRITE YOUR NAME ON THIS LABEL.
3. Place the cup in the plastic bag provided. Close the bag and keep urine cool in
the refrigerator until the Medical Research Assistant arrives.
If you are not able or for forget to collect your FIRST URINE, collect the sample the
next time you urinate.

If you have to cancel the visit for some reason:
•

Flush the collected urine collected in the toilet, rinse the cup with water and dry it. Do not use
soap to clean the cup.

•

Follow instructions #1-3 above on the day of the next scheduled visit.

•

Cross out the missed date and time on the urine cup label and clearly write the new date and time
on the label.

Urine Collection Instructions for Night Workers
You should collect your urine as described above when you normally wake up—that is after your longest
period of sleep, and BEFORE your scheduled visit with the Medical Research Assistant.

Examples:
1. George works nights as a dock worker. On Tuesday, he gets home at 7:00 am and sleeps from 9:00
am until 4:00 pm. George’s home visit appointment is Tuesday evening at 6:00 pm. George collects
his urine Tuesday afternoon when he wakes up at 4:00 pm and keeps it in the refrigerator until the
visit.
2. Beth works nights at a factory, and usually gets home from work at 9:00 am. Beth stays awake all
morning and early afternoon. She sleeps from 3:00 pm until 9:00 pm. Her appointment is for Tuesday
morning as soon as she gets home from work. Beth collects her urine Monday night at 9:00 pm when
she wakes up before going to work, and refrigerates her urine until the home visit the next morning.
