• Question 114:

  The cells indicated by the arrows in the image are spherocytes. Spherocytes have a decreased surface to volume ratio and are therefore smaller with an increased MCHC. Spherocytes have lost their bi-concave shape and are spherical in shape, hence the name.

  What are the cells that are indicated by the arrows in this peripheral blood smear image?

  

  A. Echinocytes

  B. Elliptocytes
