How is blood count?

First investigation done (but overdone), three main components (RBC count (important to look at) and HB, WBC count, and platelet count) Normal RBC (4-6 * 10^12), Hb (13.5-17.5 male and -2 for females), MCV (80-95 normal, less microcytic and more macrocytic) White cells (normal 4-7 *10^9, decrease leukopenia, increase leukocytosis, may be lymphocyte or neutrophil alone) Platelets (normal 150-400 * 10^9, low thrombocytopenia seen in poor production and increased destruction and high cytosis increase risk of blood clot)
