Resolve morphology and artifacts
On an acceptable Wright-Giemsa smear, toxic granulation means conspicuous coarse, dark cytoplasmic granules in neutrophils; a Döhle body is a pale blue-gray peripheral cytoplasmic inclusion; and cytoplasmic vacuoles are clear round spaces. Bands have a curved or horseshoe nucleus without distinct lobes; immature granulocytes include metamyelocytes and earlier granulocytic forms under local nomenclature. Reactive lymphocytes vary in size, chromatin, and abundant basophilic cytoplasm; blasts are immature cells requiring local escalation, not a diagnosis from this figure. Storage artifact can include degenerative vacuolation or nuclear/cytoplasmic deterioration in an aged specimen.
Compare feature distribution across well-spread cells and fields. Stain precipitate is irregular granular debris that may overlie cells or occur in background; it can mimic toxic granulation but does not follow neutrophil cytoplasm consistently. A platelet overlying a neutrophil can mimic a discrete inclusion; focus through the film and compare adjacent cells before calling a Döhle body. Reactive lymphocyte heterogeneity and a more uniform/monomorphic population are clues only: neither pattern alone establishes reactive versus neoplastic etiology.
In this case, a smear made at 10:05 shows mature neutrophilia with mild toxic granulation, occasional Döhle bodies, rare manual bands, and heterogeneous lymphocytes; no blasts, basophilia, or dysplasia are seen. The local reviewer resolves the IG flag by documenting these quality-smear findings, recording that no reportable immature granulocyte category is confirmed beyond the rare bands, and following the locally validated next step (release if criteria are met; otherwise repeat/review/escalate). An IG flag alone is not a morphology diagnosis.
