As the number of abnormal cells increases in the bone marrow, they may crowd out and inhibit the production of normal white blood cells, red blood cells, and platelets, and eventually abnormal cells may also be released into the blood. The main advantages of IHC are the possibility to correlate antigen expression with cell morphology and tissue architecture and the ability to detect a relatively low number of neoplastic cells, such as in Hodgkin's lymphoma (HL) or T-cell-rich large B-cell lymphoma (TCRBCL). According to the European Group for the Immunological Classification of Leukemias (EGIL), AML can be immunologically defined by the expression of atleast two of the following myeloid markers: Based on this classification, one study researched the prognostic significance of various immunophenotypic subgroups in 177 adult AML patients.

TdT and PAX5 were performed in five of the seven patients with ABLB detected by FC. Immunophenotypic abnormalities of different B-NHL subtypes are overly heterogeneous; hence, including all markers in one screening tube with kappa and lambda is difficult. NCI CPTC Antibody Characterization Program. Sometimes pieces of the abnormal myeloma protein are filtered through the kidney into the urine. Comparing cases with immunophenotypic dissimilarities to those with cytogenetic differences, no distinct patterns of association were identified.
