The laboratory requires all the urine produced over a 24 hour period to perform the test your doctor has requested. The more accurately this is done by you, the more accurate is the result the lab produces. As most individuals get out of bed at the same time each morning this is the best time to start. 8am is used in the example below.
- Day 1 – 8am: – Empty your bladder and discard the urine. We do not require this sample. From this time all urine you pass during the day must be saved into the bottle provided.
- Day 2 – 8am: – Empty your bladder and save this in the bottle. The collection is now complete.
Screw the top on tightly. Ensure your details are completed on the bottle label. Put the bottle in the plastic bag provided and seal with the elastic band. Attach the pathology request form, given to you by your doctor, to the plastic bag using the sticky strip on the form.
Your completed urine collection should be taken to pathology laboratory reception, The James Cook University Hospital, Middlesbrough, TS4 3BW, or to the Pathology Laboratory, Friarage Hospital, Northallerton, DL6 1JG or to wherever you have been instructed to take it by your doctor.
