Figure

• 

  Fig. 1 (A) Platelet counts of blood collected with ethylenediaminetetraacetic acid (EDTA), heparin, and sodium citrate and examined at 0 min, 30 min, and 120 min after venipuncture. (B) Serotonin levels of the patient and a normal control subject in blood collected with EDTA examined at 30 min and 90 min after venipuncture.

• 

  Fig. 2 (A) An ethylenediaminetetraacetic acid (EDTA) blood film 0 min after venipuncture shows agranular platelets (also called gray platelets) (arrow) partly aggregated (arrowhead) and normal platelets (×400, Wright-Giemsa stain). (B) An EDTA blood film 30 min after venipuncture shows middle-sized, aggregated agranular platelets (arrowhead) (×400, Wright-Giemsa stain). (C) An EDTA blood film 120 min after venipuncture shows giant, aggregated agranular platelets (arrowhead) (×400, Wright-Giemsa stain). (D) An EDTA blood film 120 min after venipuncture shows normal platelets, approximately 2 months after discharge (×400, Wright-Giemsa stain).
