Opening laboratory problem

An adult EDTA whole-blood specimen has a microcytic, hypochromic CBC pattern. The compact result table records the measured CBC evidence before any pattern assignment.

The peripheral smear shows marked microcytosis, hypochromia, target cells, and mild anisopoikilocytosis; no nucleated red blood cells are seen. These findings support a microcytic process but do not establish a specific disorder. Basophilic stippling, if present, is also nonspecific and requires smear and exposure correlation.

Microcytosis and hypochromia with a relatively preserved or increased RBC count support a thalassemia carrier pattern, but iron deficiency remains a competing explanation until iron status is assessed. A fractionation pattern is not a genotype: assemble CBC, smear, iron, age, and fractionation evidence before releasing an interpretation.
