Abstract:
1. A specimen sample collection system comprising: a handle having opposing first and second ends, and a sufficiency indicator coupled to the handle, wherein the handle second end and sufficiency indicator form a cavity adapted to receive a sample collection pad; a sample collection pad having opposing ends, the sample collection pad partially contained within and extending from the handle second end and in contact with the sufficiency indicator, the sample collection pad having a cylindrical cross section; a pad compression tube having a first open end to go over the sample collection pad and second end of the handle, an opposing second end, an interior surface extending therebetween, and at least outlet port proximal to the pad compression tube second end and in fluid communication with the pad compression tube interior; and, wherein the sufficiency indicator comprises a light pipe, the light pipe including a first end surface and a second surface in physical contact with the sample collection pad creating a refractive boundary, the second surface oriented at an angle of incidence to the first end surface such that when the sample collection pad absorbs a sufficient liquid sample the refractive properties of the boundary alter the observability of the first end surface.
