摘要

A sample collection device is described which comprises an absorbing material which can readily absorb and release test liquid, and which additionally comprises at least one assay reagent. The assay reagent is present in only part of the absorbing material, the remaining part of the absorbing material is located upstream the part comprising the assay reagent and serves as a reservoir for test liquid to be used as a washing fluid. The part of the absorbing material comprising the assay reagent is provided with means to prevent washing out of the assay reagent during sample taking, while allowing the availability of said assay reagent for test performance during or after sample taking.
