A device and method for collection of a urine sample is disclosed which comprises a channel, an opening in the channel, and a collector associated with the opening. The channel is formed so that urine can flow through it from a first end to a second end thereof. The opening is provided in the channel at a point between the first and the second ends thereof. The collector is associated with the opening in the channel to be able to receive urine therein. In one embodiment, a member can cover the opening to permit urine to pass through it after contact with urine. Specifically, the member may dissolve or otherwise permit urine to pass through the opening after a period of time to test a urine sample which is not from the initial flow of urine to avoid bacteria contamination.
