Which type of red cells has a decreased surface-to-volume ratio and subsequent increased osmotic fragility?

Question

Quizplus · Accepted Answer

Spherocytes have a decreased surface-to-volume ratio due to loss of their normal biconcave shape, resulting in increased osmotic fragility. Sickle cells have a decreased surface-to-volume ratio but their osmotic fragility is not necessarily increased. Hypochromic cells and teardrop cells do not have a decreased surface-to-volume ratio.
