This part of the hemogram is the most subjective and difficult to quantitate. Besides that, smudge cells and different types of leucocytes seen in this vilification. Platelet clumping, if not detected, can cause you to underestimate platelet number since there may be few individual platelets found during the high magnification examination.
The white cells here are shrunken and appear much smaller than in the quickly dried areas — individual leukocytes can be difficult to identify in this area and red blood cell changes are hard to appreciate. The thick area of a smear dries too slowly for leukocytes to spread out.
