Other markers that have been evaluated include mean platelet volume (MPV), white blood cell (WBC) count, ESR, red cell distribution width (RDW), Pentraxin-3, hyponatremia, and oxidative markers such as nitric oxide and myeloperoxidase, to name a few [10,11,12,13,33,34,35,36,37]. Here, PTX3 is linked to Hyponatremia.
