Summary

CHANGE OF THE MORPHOLOGY AND QUANTITY OF PLATELET IN THE PLATELET

CONCENTRATE AFTER SEPARATING FROM DONOR'S BLOOD UNITS USING

AUTOMATIC CELL COUNTER MACHINE

Study about the change of the morphology and quantity of platelet in platelet concentrate after

separating and preserving for blood transfusion is very necessary. Objective: Identify changes in term of

morphology and quantity of platelet concentrate separating from blood samples of blood donors using

Hemonetics and Cobe Spectra auto - machines. Methods: 20 platelet concentrate units were separated from

donor's blood samples using Hemonetics auto machine (10) and Cobe Spectra machine (10). Platelets were

counted using automatic cell counter machine Sysmex - SF 3000 and the change of platelet morphology was

observed using Electronic microscope. Result and Conclusion: both morphology and quantity of platelet and

platelet concentrate were changed after preserving for one, two, three, four and five days. Using platelet

concentrate after a long time storing may effect on the quality of treatment for the patients.

Key word: Platelet, Platelet amount and morphology, electric microscope
