Hematology
Numbers first. Then patterns, flags, films, and the clinical context that tells us whether the story holds together.

Thalassemia Trait on the CBC: When Microcytosis Does Not Fit Iron Deficiency
How RBC count, RDW, iron studies, previous results, and the blood film can point toward a thalassemia-type pattern — without turning screening clues into a diagnosis.Hematology · 18 min read
