Overview
The most important laboratory test for sickle cell anemia is a complete blood count (CBC), specifically hemoglobin and hematocrit.
Laboratory findings
Blood tests
Laboratory findings consistent with the diagnosis of sickle cell disease include:[1][2]
- Anemia
- High reticulocyte count (greater than 1.5%)
- Target cells and Howell-Jolly bodies on pripheral blood smear
- Abnormal hemoglobin forms on hemoglobin electrophoresis (Sickle-cell hemoglobin (HgbS) and hemoglobin C with sickling (HgbSC) are the two most common forms)
