What is a reticulocyte count?
Reticulocytes are red blood cells that are still developing. They are also known as immature red blood cells. Reticulocytes are made in the bone marrow and sent into the bloodstream. About two days after they form, they develop into mature red blood cells. These red blood cells move oxygen from your lungs to every cell in your body.

A reticulocyte count (retic count) measures the number of reticulocytes in the blood. If the count is too high or too low, it can mean a serious health problem, including anemia and disorders of the bone marrow, liver, and kidneys.

Other names: retic count, reticulocyte percent, reticulocyte index, reticulocyte production index, RPI

What is it used for?
A reticulocyte count is most often used to:

Diagnose specific types of anemia. Anemia is a condition in which your blood has a lower than normal amount of red blood cells. There are several different forms and causes of anemia.
See if treatment for anemia is working
See if bone marrow is producing the right amount of blood cells
Check bone marrow function after chemotherapy or a bone marrow transplant
Why do I need a reticulocyte count?
You may need this test if:

Other blood tests show your red blood cell levels are not normal. These tests may include a complete blood count, hemoglobin test, and/or hematocrit test.
You are being treated with radiation or chemotherapy
You recently received a bone marrow transplant
You may also need this test if you have symptoms of anemia. These include:

Fatigue
Weakness
Shortness of breath
Pale skin
Cold hands and/or feet
Sometimes new babies are tested for a condition called hemolytic disease of the newborn. This condition happens when a mother's blood is not compatible with her unborn baby. This is known as Rh incompatibility. It causes the mother's immune system to attack the baby's red blood cells. Most pregnant women are tested for Rh incompatibility as part of routine prenatal screening.
