Abstract
An oral fluid collection device includes a plunger and funnel to simultaneously collect and split a single specimen into metered doses for drug testing. The device may be used with collection tubes for collection of the metered doses and later testing. The device, when used, drives the metered dose into the collection tubes and removes bubbles in the specimen to provide improved accuracy in testing.
