Improvements in blood collection and testing. In one aspect, an improved method of manufacturing a blood collection tube, particularly illustrated for use in sedimentation rate testing, including providing an elongated glass tube with an open first end for receiving a venipuncture blood sample of at least 1 ml, formed with a closed end opposite the first end; and applying to a substantial portion of the receptacle a containment barrier. The improvements also pertain to resulting blood collection tubes, additives for blood collection tubes that permit reliable sedimentation test data after 8 hours from the blood draw, and methods of administering health care using the aforenoted tubes, additives or both.

What is claimed is: 1. A method of managing the diagnosis and treatment of a condition, comprising the steps of: a) coordinating the delivery of a blood sampling kit to at least one remote blood draw site, where blood samples are drawn from each of a plurality of persons directly into a tube corresponding to each person, wherein each tube has a containment barrier on the exterior of the tube and a surfactant inside of the tube; b) performing an erythrocyte sedimentation rate (ESR) analysis on each of the plurality of blood samples located in the tubes at a remote site more than 6 hours after each sample is drawn; c) receiving information at any site about the results of the ESR analysis of each blood sample; and d) based on the results, coordinating administering a pharmacological therapy to a plurality of such persons whose blood sample indicates treatment is necessary. 2. The method of claim 1, wherein the coordinating step (a) includes providing an elongated glass tube with an open first end for receiving a venipuncture blood sample of at least 1 ml, formed with a closed end opposite the first end. 3. The method of claim 2, further comprising applying to a substantial portion of the glass tube a containment barrier that is sufficiently transparent that accurate and reproducible sedimentation rate tests are obtainable by an optical detection technique, and following a fracture of the tube, blood is contained within the tube. 4. The method of 3, further comprising a step of evacuating the elongated glass tube to below atmospheric pressure and sealing the evacuated glass tube. 5. The method of claim 3, further comprising a step of introducing into the tube, prior to introducing any blood, an additive including a surfactant and at least one additional additive selected from the group consisting of an anti-microbial, an anti-coagulant, a preservative, and any combination thereof. 6. The method of claim 5, wherein the surfactant is a nonionic surfactant of the form Cx Ey, where C is an alkyl chain and E is a polyoxyethelyne chain, x is the number of carbons in the alkyl chain (C) and y is the number of ethyiene oxide units in the polyoxyethylene chain (E). 7. The method of claim 6, wherein x is from about 6 to about 18 and y is from about 4 to about 40. 8. The method of claim 7, wherein the surfactant is present 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 12 hours. 9. The method of claim 8, further comprising refrigerating the blood sample before testing it. 10. The method of claim 9, wherein the temperature of the sample is maintained between about 2 to about 10�� C. 11. The method of claim 8, further comprising maintaining the blood sample at ambient temperature before testing it.
