Platelet counts and histograms within normal limits in EDTA on hospital admission (a), in sodium citrate (c), and in heparin (d). The EDTA aliquot obtained six days after admission presented multiple peaks and a depressed curve's height suggesting respectively platelet aggregation and thrombocytopenia (b). X-axis in femtoliters.

Abnormal platelet histogram and white blood cell (WBC) also suggested in vitro platelet clumping (Figures 1 and 2).
WBC histograms of a sample drawn six days after admission. A left peak in the ghost zone (<50 femtoliters) suggesting platelet clumping is absent in sodium citrate (a) but present in EDTA (b). X-axis in femtoliters.
