Reticulocyte count is a blood test that can reflect the production level of red blood cells in the blood. This test is characterized by the ability to count reticulocytes, a type of blood cell that is produced in the bone marrow and then released into the peripheral blood.

The main components of blood include plasma, white blood cells, platelets, and red blood cells. White blood cells help fight infection, red blood cells transport oxygen to tissues in the body, and platelets help with blood clotting, preventing bleeding. When any of these components is disrupted, serious physical imbalances can occur.
