Collection Instructions Refrigerate the collection container during the period of the collection.

Note that the minimum acceptable time period for a 'timed' collection is 6 hours.

Results of collections of less than 24 hour duration will be adjusted to reflect a '24 hour collection'. The limited time of collection as well as the need to adjust the values to be comparable to the '24 hour' normal ranges will inherently affect the accuracy of the results.
