Abstract
A platelet reference control and method of preparation in which a minor amount of solid polyethylene glycol is added either to the platelet suspension or the diluent for the platelet suspension whereby time and agitation stabilization are both achieved.
Claims5
A method of preparing a fixed platelet reference control comprising the steps of stabilizing a fixed platelet reference control against false counts due to container adsorption by adding a solid polyethylene glycol as a stabilizing agent to one member selected from the two member class consisting of an aldehyde fixed platelet suspension member and an isotonic diluent member for a platelet suspension, and thereafter adding the other member to the mixture resulting from the first adding step whereby a control is achieved that is substantially time and agitation stable.
