Flow lymphoma is used in the case of lymphoid neoplasms or when a lymphoid origin is suspected on the basis of cell morphology after staining. What is Immunophenotyping?. Among T-cell populations outside the thymus, phenotypes associated with malignancy included 1) loss of pan-T antigens (including loss of the beta chain of the T-cell antigen receptor), 2) coexpression or loss of T-subset antigens, 3) Leu-6+ T-lineage, and 4) MB-1+ T lineage. The type of sample to be tested is up to your healthcare practitioner and must be representative of your cancer.
