What it measures
Counts nucleated red blood cells, young red cells that still have a nucleus, the cell’s control center. They normally stay in your bone marrow, so adults usually have none in their blood.
Why it matters for women
Adults normally have none of these cells in their blood, and that’s the same for women and men. Anemia is common in women, but these cells may appear only when anemia is severe or the body is under major strain, such as a serious illness or a large blood loss.
You might check it if…
- a past blood test showed severe anemia
- you’ve had a large blood loss recently
- a doctor mentioned an inherited blood condition such as thalassemia
- you’re getting a routine blood count as part of a checkup
What your result may mean
High Absolute Nucleated Rbc: what it may mean
A high or measurable nucleated red blood cell count may point to bone marrow stress from severe anemia, low oxygen or marrow infiltration, when abnormal cells crowd the marrow. Adults may have none in their blood, so any found can prompt a closer look. It can happen with a large blood loss, serious illness, fast red cell breakdown (hemolysis) or inherited conditions like thalassemia and sickle cell disease. Anemia can be common in women, but these cells may appear only when it's severe. Symptoms can include deep tiredness, shortness of breath or pale skin.
Low Absolute Nucleated Rbc: what it may mean
A low or zero nucleated red blood cell count can be the normal adult result, because red cells can push out their nucleus before they leave the bone marrow. Newborns can have some in their blood for a short time, but adults may have none. This may be the same for women and men. A zero here can't rule out anemia, so your hemoglobin, hematocrit and iron tests may say more about that.
