English: Illustration of complete blood count and differential (hemogram, full blood exam, leukogram etc.) test results with blood specimen in EDTA tube. N.B. these are my own CBC and diff results so no patient confidentiality issues. Symbol key: CBC, complete blood cell count; WBC, white blood cell count (leukocyte count); RBC, red blood cell count (erythrocyte count); HGB, hemoglobin level; HCT, hematocrit; MCV, mean corpuscular volume; MCH, mean corpuscular hemoglobin (per erythrocyte); MCHC, mean corpuscular hemoglobin concentration; RDW-CV, red blood cell distribution width–coefficient of variation; PLT, platelet count (thrombocyte count); MPV, mean platelet volume; NEUT, neutrophil count; LYMPH, lymphocyte count; MONO, monocyte count; EO, eosinophil count; BASO, basophil count; IG, immature granulocyte count; NRBC, nucleated red blood cell count; EDTA, ethylenediaminetetraacetic acid, a preservative that makes the blood sample last long enough to be processed (it inhibits coagulation by chelating calcium ions).
