What is a "poikilocyte"?

A poikilocyte refers to an atypical or irregularly shaped red blood cell characterized by its distorted morphology. These irregularities can manifest as various shapes, such as teardrop, oval, or fragmented forms. Poikilocytes are often observed in conditions associated with altered red blood cell production or destruction, such as anemias, certain genetic disorders, or certain types of infections. The presence of poikilocytes in a blood sample can provide valuable diagnostic information and may indicate an underlying health issue that requires further investigation.
