Dendritic Cell and Monocyte Enumeration. This test enumerates plasmacytoid dendritic cells (pDC), myeloid dendritic cells (mDC), and classical monocytes. It can be used as part of the diagnostic assessment of patients suspected of defects in innate immunity, particularly those in monocyte and dendritic cell development, which can manifest in isolation or as part of a broader clinical phenotype.

Monocyte Subset Quantitation – Monocytes reflect the monocyte/macrophage or mononuclear phagocytes in circulation. The majority of CD14high cells found in human blood are classified as classical monocytes while a very minor population (in healthy controls) of cells express low CD14 and high CD16 and are described as non-classical monocytes. The population between these two are referred to as the transitional subset. It is useful to quantitate and evaluate monocyte subsets in the context of certain primary immunodeficiencies (inborn errors of immunity) where such cell populations are clinically informative. Monocyte subsets can also be skewed in the context of severe infection, HIV-1 infection, therapy with steroids and other immunomodulatory agents, and are critical regulators of inflammation. There is also some evidence that the absolute count of transitional monocytes can predict cardiovascular events. Monocyte subsets in blood varies substantially during life from the neonatal period into adulthood.
