The spleen is an organ that normally stores about one-third of the body's platelets. It also helps your body fight infection and remove unwanted cell material. can be caused by Valproate Neutropenia A normal ANC is above 1,500 cells per microliter. An ANC less than 500 cells/μL is defined as neutropenia and significantly increases the risk of infection. Neutropenia is the condition of a low ANC, Clozapine - WBC => 3500 to initiate therapy, ANC MUST BE =>2000/mm, ck wbc/anc weekly x 6 months, then Q other week for 6 months; if stable then Q 4 weeks. after therapy test for at least 4 weeks, LIVER PANEL ALP, AST, ASP, BILIRUBIN, ALBUMIN, TTL PROTEIN, CBC with WBC DIFFERENTIAL, PLATELET COUNT.
