ABSTRACT:
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.
