Abstract: The present invention relates to a tube for collecting specimens. The tube includes a tubular body having an inner surface which defines a hollow space for carrying a carrier solution or the like. The tube also includes a plurality of ridges projecting inwardly from the inner surface for engagement with at least a portion of a specimen collection tool for facilitating release of at least some of specimens therefrom.

Abstract: A swab includes a stick having a handgrip section and a tip section. The tip section includes a plurality of lobes arranged axially along a longitudinal axis of the stick. More particularly, the lobes include a first lobe located at a distal end of the stick and at least one second lobe axially offset from the first lobe. The diameter of the first lobe is smaller than the diameter of the second lobe. Fibers are attached to the tip section for collecting a specimen from an anatomical cavity of a patient. A stop plate may also be provided for removable attachment to the stick for adjusting the extent to which the tip section can be inserted into the cavity.
