Reticulocyte count
Informed by recognized medical guidance
Overview
A reticulocyte count is a blood test that measures the number of young red blood cells (reticulocytes) in your blood. It helps show how well your bone marrow is making new red blood cells.
Key facts
- Reticulocytes are immature red blood cells that mature in about 1 to 2 days.
- This test is often used to help diagnose and monitor types of anemia (low red blood cells).
- A high reticulocyte count usually means your body is trying to make more red blood cells, often because of blood loss or destruction of red blood cells.
Yes, this is a common blood test that may be done as part of a complete blood count (CBC) or separately when doctors need to check bone marrow activity.
It is used in people of all ages who have symptoms of anemia, bleeding disorders, or conditions affecting the bone marrow.
