Abstract
Method for obtaining a fluid sample from a collection device which includes assembling cap and fluid-holding vessel components of the collection device to contain and isolate a specimen retrieval device adjacent a side wall of the vessel. The position of the specimen retrieval device within the collection device is such that the specimen retrieval device does not substantially interfere with the movement of a fluid transfer device into or out of the assembled collection device. The fluid transfer device is used to draw and remove a fluid substance from the collection device for analysis.
