Terminology
Void Containers
A 'container' that is used temporarily to collect a void that is added to a interval collection (storage) container.
These void containers are barcoded to ensure that the right void goes with the right interval collection container for the right subject.
Sometimes the same void container is used in an interval, or, new void containers are used for each void.
Interval Collection (Storage) Containers
These are the interval container 'jugs' that are used to store the void in (for the fridge, etc).
The number of needed collection containers for an interval is unknown. If a subject is voiding a lot, they may need to add several collection containers to an interval.
Note
Focuses on a simple urine collection interval process (e.g. does not include a 'clean catch')
It's possible for there to be 0 (zero), 1 or several urine voids in an interval. Shorter intervals are unlikely to have many voids and longer intervals are unlikely to have 0 or few voids if kidney function remains unaffected and compliance is good
Safety precautions and associated best practices are out of the scope of this workflow
Attempts to design a process that does not require a urine monitoring log or a checker
Start Interval
Within Data Collection:
Scan Start Event barcode label on pooling container to open event (or open event manually > Interval PK Start form)
Scan subject wristband to verify correct subject
Scan Container Start Barcode again
Container is confirmed to belong to the subject for that collection interval
Document the start date/time of interval
Store container for use within the interval

Collect Urine Void in Interval
Note
A urinal has been used in the following examples, but may just as easily and interchangeably show a hat.
Within Data Collection:
Scan subject wristband
Press “Add New” within form to add a new void
Scan urinal (void container) as applicable
Void container is confirmed to belong to the subject for that interval collection
Subject voids and time of collection is documented
Scan barcode on interval collection container
Scan urinal or hat as applicable
Weight
Sometimes weight is required for each void but not always

Pooling (Interval Collection) Container is confirmed to match the urinal (void container) for that interval collection for that subject.
1.
2.
Poor freshly voided urine into the pooling container
Pour this >
into this
Place the pooling container into the fridge
Rinse and retain the urinal for the next void OR
A new void container is provided each time a subject voids
Repeat as necessary until the end of the interval.
End Interval
Within Data Collection:
Scan Stop Event barcode label on pooling container to open event (or open event manually > Interval PK Stop form)
Scan subject wristband to verify correct subject
Container is confirmed to belong to the subject for that collection interval
Document interval end date/time
Measure volume of total amount of urine collected in the interval and record this on the Stop Event form
Mix pooled collection thoroughly
Within Sample Processing:
Scan Stop Event Label
Scan urine aliquot tubes for the interval
Transfer applicable quantities of urine to the urine aliquot containers.
Using the scanner at each step, pack the aliquots into appropriate containers and place them in the applicable freezer.
