Analyze Red Cell Distribution Width (RDW) with MCV to help differentiate anemias. RDW-CV reference ≈ 11.5–14.5%, RDW-SD ≈ 39–46 fL (lab-dependent). Elevated RDW reflects anisocytosis. Classic Bessman patterns: high RDW + low MCV → iron deficiency anemia (IDA), which raises the RDW early — before MCV/Hb fall; normal RDW + low MCV → thalassemia trait (uniform microcytosis). Other patterns: high RDW + high MCV → megaloblastic anemia (B12/folate), MDS, drugs, hemolysis with reticulocytosis, preleukemia, or mixed populations (combined iron + B12 deficiency, post-transfusion); high RDW + normal MCV → early/mixed nutritional deficiency, dimorphic anemia, marrow recovery; normal RDW + normal MCV → anemia of chronic disease is classically normocytic. Interpret with Hb, ferritin, Hb electrophoresis, and clinical context. Based on Bessman 1983 and Teixeira 2014. Not medical advice.

POST https://api.elysiatools.com/en/api/tools/rdw-analyzer| Name | Type | Required | Description |
|---|---|---|---|
| rdwForm | select | Yes | RDW-CV (coefficient of variation, %) is most commonly reported; RDW-SD is the distribution width in fL. |
| rdw | number | Yes | RDW value in the unit selected above (RDW-CV in %, RDW-SD in fL). |
| mcv | number | Yes | Mean corpuscular volume in fL. Reference ~80–100 fL (lab-dependent). |
| decimalPlaces | number | No | — |
