Two factors contribute to the MCHC rise in spherocytes: 1) the geometric efficiency of a sphere to enclose the largest possible volume with the smallest possible surface area and 2) some dehydration that causes true hemoglobin concentration within the cells to rise.

WebRBC populations with a normal MCHC value are normochromic. Spherocytes can have an elevated MCHC. Red cells defend their MCHC over their MCV (preserving hemoglobin at the expense of RBC size), which is why microcytosis occurs with iron deficiency and with impaired hemoglobin synthesis. caliber home loans defermentWebSpherocytes are cells that contain more hemoglobin than normal in relation to cell volume—the arrows in the lower image on the right point to spherocytes.
