Neopterin is a molecule produced by immune cells, particularly macrophages, in response to stimulation by interferon-gamma. It is considered a marker of immune system activation and inflammation. Elevated levels of neopterin in urine or blood can indicate increased immune activity, often seen in infections, autoimmune disorders, or chronic inflammatory conditions. Because it reflects cellular immune response, neopterin is sometimes used to monitor disease progression or immune system status.
Neopterin is a compound released by immune cells when the immune system is activated, serving as a marker of inflammation and immune response.
Elevated neopterin levels can suggest increased immune activity, which may occur during infections, autoimmune diseases, or chronic inflammation.
Not directly. While high neopterin suggests immune activation, it is a non-specific marker and must be interpreted in context with other clinical findings.
