**for research purposes only
Interpretation: CD1a=1%
The above results were obtained by
gating on blasts only.
PRELIMINARY: Specimen presents with suspect abnormal blast population (-15%).
LAIP indicative of residual AML presence with aberrant CD58 expression.
Correlation with clinical, cytogenetic and histopathologic data is recommended.
Addendum: The suspect abnormal blast population exhibits large cell size with a heterogenous SSC pattern based on FSC/SSC dot plot.
Normal lymphocytes are prominent (-67%) composed entirely of T cells.
