However, it also helps in knowing what amount of healthy cells are making healthy blood cells to rule out chronic cases of anemia or thrombocytopenia. A needle is inserted in the bone and then marrow is extracted which is known as bone marrow aspiration.
An MCV test measures the size and volume of red blood cells. A normal MCV range is roughly 80-100 fl . If someone's MCV level is below 80 fl, they will likely develop or have microcytic anemia. Alternatively, if their MCV levels are greater than 100 fl, they could experience macrocytic anemia
Bone marrow is found in the center of most bones and has many blood vessels. There are two types of bone marrow: red and yellow. Red marrow contains blood stem cells that can become red blood cells, white blood cells, or platelets. Yellow marrow consists of fat and stem cells that produce cartilage and bones in the body.
