Abstract
A method for collecting a sample of fluid specimen from a patient for diagnostic testing, providing a specimen collecting device comprising a hollow tubular member, 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. Around the hollow tubular member is slidably mounted a flexible sleeve member having a first end that fits snugly around the hollow tubular member and a second end with an enlarged diameter that can surround the uncompressed foam member.
