A collection and test device for a rapid test is provided. The device comprises a test fluid accommodation part having a test fluid accommodation space, a test paper accommodation part having a test paper accommodation space, and a collection probe having a channel for the test fluid to flow out from the collection probe. The two ends of the test paper accommodation part are respectively connected to the test fluid accommodation part and the collection probe, and the test paper accommodation space communicates with the channel of the collection probe. The test fluid accommodation space and the test paper accommodation space are separated from each other by a temporary barrier. The temporary barrier can be manually removed or broken to make the test fluid accommodation space communicate with the test paper accommodation space. The device of the present invention can provide the test results conveniently and rapidly.
