Abstract

Disclosed herein is a sample recovery and collection device comprising a tube, a cap, an insert, and an opening. The cap includes an O-ring and is removably secured to the tube for sealing the tube. The insert includes a first end having a ring that is adhered to the tube and second end opposite the first end. The insert also includes a first leg, a second leg, and a third leg, each coupled to and extending from the ring to the second end. The opening extends from the ring to the second end and the insert defines a diameter. Also disclosed herein is a kit comprising the sample recovery and collection device. Further disclosed herein is a method of collecting a sample from a subject.

Claims

1. A method of collecting a sample from a subject, the method comprising:

(a) providing a sample recovery and collection device comprising;

a tube;

a cap including an O-ring, the cap removably secured to the tube for sealing the tube;

an insert including a first end having a ring that is adhered to the tube and a second end opposite the first end, the insert including a first leg, a second leg, and a third leg each coupled to and extending from the ring to the second end; and

an opening extending from the ring to the second end, the insert defining a diameter,

wherein each of the first, second and third legs includes a plurality of concentric protrusions that project radially from an inside surface of each of the legs;

(b) contacting a tip of a swab against a body portion of the subject to obtain the sample;

(c) inserting the swab tip through the opening of the insert; and

(d) transferring the sample from the swab tip to a solution enclosed within the tube.

2. The method of claim 1, wherein the sample comprises buccal cells.

3. The method of claim 1, wherein inserting further comprises applying pressure to the swab tip to cause the sample to be squeezed from the swab tip into the tube to mix with the solution.

4. The method of claim 1, further comprising:

(e) contacting a tip of a second swab against the body portion of the subject to obtain a second sample;

(f) inserting the second swab tip through the opening of the insert; and

(g) transferring the second sample from the second swab tip to the solution enclosed within the tube.
