What is a "macrocyte"?

A macrocyte, also known as a macrocytic red blood cell, is an abnormally large cell found in the bloodstream. They are often associated with conditions such as vitamin B12 deficiency, folic acid deficiency, or certain medications. Macrocytes can be observed under a microscope during a blood smear examination and their presence may indicate an underlying health issue. The identification of macrocytes can help healthcare professionals in diagnosing and managing the underlying cause of their appearance.
