Blood & Lymphoid Tumor Package - Immunohistochemistry: CD123 Diagnostic Package

This diagnostic package, based on immunohistochemistry, involves testing for a range of markers to diagnose and differentiate proliferative tumors of the bone marrow, blood, and lymph nodes. The package primarily includes testing for CD123 (interleukin-3-alpha receptor, a marker for plasmacytoid dendritic cells), along with essential complementary markers: CD34 (a stem cell/blast cell marker), CD117 (c-KIT) (a bone marrow/mast cell marker), and a lymphoid marker such as CD20 or CD3. The package aims to differentiate between myeloid tumors (e.g., acute myeloid leukemia - AML) and lymphoid tumors (especially hairy lymphoma - HCL), and to identify subtypes such as dendritic plasmacytoma (BPDCN).
