Final answer:
Aniso-cytosis refers to cells of varying sizes, particularly noticed in red blood cell populations, and can indicate various types of anemias.
Step-by-step explanation:
Aniso-cytosis refers to cells of varying sizes. It is a term used in the morphology of red blood cells (RBCs) when describing the size variation found in a sample of blood. In medical diagnostics, it is essential to measure the mean corpuscle volume (MCV), which determines the average size of RBCs. Normal-sized cells are called normocytic, while cells that are smaller or larger than normal are described as microcytic or macrocytic, respectively. The presence of aniso-cytosis can be an indicator of various types of anemias or other hematologic disorders. This condition can impact the delivery of oxygen to body tissues, potentially causing symptoms such as fatigue, lethargy, and an increased risk for infection.
