A sample of the collected specimen is removed from the device for analysis by means of a detachable transferring stick, one area of which is the sample collecting portion of the device and another area of which is an integral handle. The device also provides for the collection of a liquid sample drained from a defined volume of a semi-solid specimen through porous screen and collected on the detachable transferring stick. A sample of the specimen or liquid from it may be flushed from the stick for a qualitative or quantitative determination of analyte.
