Indicator Explainer
Soluble Monocyte Differentiation Antigen CD14
Soluble monocyte differentiation antigen CD14 is encoded by the human CD14 gene. This soluble protein may be used as a marker of monocyte activation and is derived either through cleavage that removes the glycophosphoinositol (GPI)-anchor from the membrane bound form of CD14 or as non-cleaved form secreted from the non-GPI-modified intracellular pool of CD14.
This page explains what the indicator is and how results are interpreted in general terms. Reference ranges depend on the laboratory, the method, and your own situation — no single “normal value” applies to everyone. This page is health information, not a diagnosis. For symptoms, treatment, or urgent concerns, contact a healthcare professional.
