Scanning electron microscopy (SEM) of echinocytes Echinocyte compared to other forms of poikilocytosis. Echinocyte (from the Greek word echinos, meaning 'hedgehog' or 'sea urchin'), in human biology and medicine, refers to a form of red blood cell that has an abnormal cell membrane characterized by many small, evenly spaced thorny projections.
Poikilocytes may be oval, teardrop-shaped, sickle-shaped or irregularly contracted. Normal red blood cells are round, flattened disks that are thinner in the middle than at the edges. A poikilocyte is an abnormally-shaped red blood cell. [1]

Sickle cell disease: In a healthy individual, the HBB gene is responsible for encoding hemoglobin which carries oxygen throughout the body. [16] However, when a person has this disease due to inheriting two mutated copies of the HBB gene due to a base pair point mutation, their red blood cells are shaped differently. [16]
An "All Apps" screen lists all installed applications, with the ability for users to drag an app from the list onto the home screen. The app list may be accessed using a gesture or a button, depending on the Android version. A "Recents" screen, also known as "Overview", lets users switch between recently used apps. [89]
A complete blood count (CBC) may show increased reticulocytes, a sign of increased red blood cell production, and decreased hemoglobin and hematocrit. The term "non-hereditary spherocytosis" is occasionally used, albeit rarely. [2] Lists of causes: [3] Warm autoimmune hemolytic anemia; Cold autoimmune hemolytic anemia/paroxysmal cold hemoglobinuria
