RT Journal Article SR Electronic T1 Relationship of platelet retention in glass bead columns to the rate of aggregation with adenosine diphosphate and thrombin JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 560 OP 562 DO 10.1136/jcp.22.5.560 VO 22 IS 5 A1 Bloom, A. L. A1 Evans, E. P. YR 1969 UL http://jcp.bmj.com/content/22/5/560.abstract AB The initial rate of platelet aggregation induced by adenosine diphosphate and thrombin correlated with the number of platelets retained when samples of citrated blood from the same normal donors were passed through glass bead columns. The results support the view that the glass bead column method of measuring platelet `adhesiveness' is influenced by platelet aggregation.
