Reticulocyte Count
Reticulocytes are young, immature red blood cells. Their count shows how quickly your bone marrow is producing new red blood cells.
Category: Complete Blood Count
Also known as: reticulocyte count, reticulocytes, retic, retic count, reticulocyte %, Polychromatophilic red cells, retikulociti
Reference range: 0.5–2.5 % (Source: ABIM)
Standard unit: %
High values may indicate
High reticulocyte count may indicate hemolytic anemia, blood loss, or bone marrow response to treatment for anemia.
Low values may indicate
Low reticulocyte count may indicate bone marrow failure, aplastic anemia, nutritional deficiency, or kidney disease.
Frequently asked questions
- What is a normal Reticulocyte Count level?
- A typical reference range for Reticulocyte Count is 0.5–2.5 % (source: ABIM). Reference ranges vary by laboratory, age, and sex, so always compare against the range on your own lab report.
- What units is Reticulocyte Count measured in?
- Reticulocyte Count is most commonly reported in %. Labs in different countries may use other units — you can convert between them with BloodId's blood test unit converter.
- Where do Reticulocyte Count reference ranges come from?
- BloodId uses ABIM standard reference ranges and educational information from MedlinePlus (see our methodology). Reference ranges still vary by lab, age, and sex, so always compare against your own report.
- Can I track Reticulocyte Count over time?
- Yes. Upload results from any lab and BloodId charts your Reticulocyte Count over time against its reference range, so you can see whether the trend is rising, falling, or stable.
