Abstract

A device for detecting the presence or amount of an analyte in a fluid sample and method thereof, comprises a sample collector and a receiving cup for receiving and holding the sample collector within the receiving cup. The sample collector contains a compressible absorbent member for collecting the fluid sample, and has a first position and a second, locked position within the receiving cup. The absorbent member is uncompressed in the first position and is compressed in the second, locked position. The sample collector or the receiving cup has at least one test element having reagents for detecting the presence or amount of the analyte in the fluid sample.
