Abstract:
1. A kit for performing a blood sedimentation rate analysis, comprising: a) a substantially optically clear glass tube having an overall length of about 100 to about 300 mm and a wall thickness of about 0.5 to about 1.5 mm, and having a plastic containment barrier that covers substantially the entirety of the outer surface of the tube with a thickness of less than about 1 mm and a closed end, and containing an additive including a polyoxyethylene lauryl ether surfactant that is free of clouding under the conditions to which it will be exposed prior to and during sedimentation rate testing and at least one additional additive selected from the group consisting of an anti-microbial, an anti-coagulant, a preservative, or any combination thereof, wherein the surfactant is present in the tube in sufficient amount that it is capable of providing reproducible sedimentation rate tests in a consistent and reproducible manner that approximates that of a fresh blood sample after a delay of more than about 6 hours; and b) at least two components for performing a blood sedimentation rate analysis selected from the group consisting of an alcohol swab, gauze, a tube holder, a tube rack for performing a blood sedimentation rate analysis, a tourniquet, a glove, another cell collection tube, needle, lancet, adhesive strip, syringe, test strip, glass or plastic strip containing reagents for cell analysis, packaging to store any desired components, packaging to transport a blood sample stored in the tube after collection, a timer, a worksheet, or any combination thereof.
