A specimen collecting device is disclosed. The device has an elongated foam member that is circumscribed by a hollow tubular member along a portion of its longitudinal axis. The hollow tubular member has a cross sectional area less than the uncompressed cross sectional area of the foam member so that the foam member is compressed along the circumscribed portion.

1. A specimen collecting device useful for collecting a fluid specimen for diagnostic testing consisting essentially of an elongated absorbent foam member having a longitudinal axis and an uncompressed cross sectional area, the elongated foam member being circumscribed by an elongated hollow, one-piece tubular member having a flexible side wall along a portion of the longitudinal axis, the hollow tubular member having a cross sectional area less than the uncompressed cross sectional area of the foam member so that the foam member is compressed by the hollow tubular member along the circumscribed portion,wherein the foam member consists of a material suitable for collecting a specimen of a patient fluid and the foam member remains circumscribed by the tubular member during collection of the specimen, andwherein pressure can be exerted on the side wall of the tubular member to compress the foam and deliver a sample of the fluid specimen.2. The specimen collecting device of claim 1, wherein the hollow tubular member is made of paper or plastic.3. The specimen collecting device of claim 1, wherein the foam member comprises a material selected from the group consisting of polyurethane foam, polyethylene foam, polyvinylchloride foam, ethylvinylacetate foam, polyethylene/ethylvinylacetate foam, polyester foam and polyether foam.4. The specimen collecting device of claim 1, wherein the foam member comprises a polyurethane foam.5. The specimen collecting device of claim 1, wherein the foam member has a mean diameter in an uncompressed state, and wherein the foam member protrudes from an end of the tubular member a distance of about 25% to about 125% of said mean diameter of the uncompressed cross sectional area of the foam member.6. The specimen collecting device of claim 1, wherein the hollow tubular member has a length of from about 1.0 inch to about 5.0 inches.7. The specimen collecting device of claim 1, wherein the hollow tubular member has a mean diameter of from about 0.12 to about 0.5 inch.8. The specimen collecting device of claim 1, wherein the hollow tubular member has a length of from about 1.5 inches to about 3.5 inches.9. The specimen collecting device of claim 1, wherein the hollow tubular member has a mean diameter of from about 0.18 to about 0.38 inch.10. A specimen collecting device useful for collecting a fluid specimen for diagnostic testing consisting essentially of an elongated absorbent foam member having a longitudinal axis and an uncompressed cross sectional area, the elongated foam member being circumscribed by an elongated hollow tubular member having a flexible side wall along a portion of the longitudinal axis, the hollow tubular member having a cross sectional area less than the uncompressed cross sectional area of the foam member so that the foam member is compressed by the hollow tubular member along the circumscribed portion,wherein the hollow tubular member has a mean diameter of from about 0.12 to about 0.5 inch,wherein the foam member consists of a material suitable for collecting a specimen of a patient fluid and the foam member remains circumscribed by the tubular member during collection of the specimen, andwherein pressure can be exerted on the side wall of the tubular member to compress the foam and deliver a sample of the specimen.
