ABSTRACT:
A predetermined number of small latex beads is provided in the vacuum capsule of a Vacutainer. After blood is drawn into the capsule, the capsule is agitated to mix the blood and beads into a homogeneous suspension. A smear or spun slide is prepared of the suspension for microscopic analysis. The beads in the microscope field are counted in addition to the white blood cells, thereby enabling calculation of the volume of blood in the microscope field to provide an absolute white cell count. Absolute red cell, platelet and differential white cell counts are obtained in the same manner. The beads have a predetermined uniform size and color density thereby enabling cell size and hemoglobin percentage measurements.
