RANTES test, CCL5 chemokine determination
This test is done to measure RANTES (Regulated upon Activation, Normal T cell Expressed and Secreted), also known as CCL5, a chemokine involved in attracting immune cells such as T cells, eosinophils, and monocytes to sites of inflammation. It plays a role in immune response, chronic inflammation, allergic conditions, and some infectious or autoimmune diseases. It is often used in specialized or research settings.
