Urine collection and fluid intake schedule
Urine samples should be collected every thirty minutes, as described below
Analyze each sample as soon as is convenient avoid letting too many samples
accumulate
1. At the beginning of the lab period, each subject should empty his or her
urinary bladder and note the time. Do not collect this sample
2. After thirty minutes, again empty the bladder, this time collecting the full
sample. This sample will serve as a pre-treatment control
3 Immediately after step 2, subjects 1-3 should drink the fluid appropriate to
their treatments as quickly as possible. If the sample cannot
be finished
before the first post-treatment sample is taken (below), record the
volume
that was drunk
Thirty minutes after step 2, each subject should again empty his or her
bladder, collecting the full sample. Repeat this step twice more, every thirty
minutes
