Immunophenotypic analysis of non-Hodgkin's lymphomas. None of the tested antigens were linked to treatment outcome. However it is frequently misdiagnosed because of its non-specific imaging and histological pattern. An internal organ may or may not be a little bigger or a little smaller than normal but this is insignificant and no cause for worry. The screening panel will be charged based on the number of markers tested (FIRST for first marker, ADD1 for each additional marker). This test was developed using an analyte specific reagent. The results from your immunophenotyping are compared to the pattern of antigens for normal cells as well as to patterns that are associated with abnormal cells (e.g., cells present with leukemias and lymphomas).
