One Hour Protocol:
(1) Weigh a urine pad in grams.
(2) Place the pad.
(3) Have the patient drink 500 mL of liquid and start the 1 hour period.
(4) For minutes 0 to 15 the patient sits or rests.
(5) For minutes 16 to 45 the patient walks and climbs stairs.
(6) For the final 15 minutes the patient
(6a) Sits and stands 10 times.
(6b) Coughs 10 times.
(6c) Runs on the same spot for 1 minute.
(6d) Picks up an object from the floor 5 times.
(6e) Wash hands for 1 minute.
(7) Retrieve and weigh the pad.
urine leakage in grams =
= (weight of the pad after 1 hour) - (initial weight of the pad)

2 - 10 grams

slight to moderate

If the specific gravity of the urine is known then the actual volume can be estimated as:
volume in mL =
= (change in weight) / (urine specific gravity)
