<p>An improved specimen test unit is provided for use in the collection and analysis of a biological specimen or the like. The test unit includes a swab member (12) having a hollow shaft (22) closed at a rear end by a break-off nib (18), and a swab tip (24) at a front end for collecting a selected specimen. The swab shaft rear end is carried by a housing base (14), with the break-off nib extending into a reagent chamber (36) having a selected reagent therein. The housing base is sufficiently deformable to break the nib and thereby permit reagent delivery through the swab shaft to contact a collected specimen on the swab tip. In a preferred form, a housing cap (16) removably interfits with the housing base to define a specimen chamber with the swab tip enclosed therein, with the housing base and/or cap being conveniently formed from blow molded plastic.</p> |
