answer question #2 a-f
e.) What is the prognosis for those effected? Check Your Understanding 1. When someone is admitted to the hospital, one of the first procedures that health professionals perform is a blood draw. One lab value that is checked is a white blood cell (WBC) count. If the WBC count is high (normal range - 4,000 -11,000/mma, this could indicate the presence of an infection. Further analysis (called a differential) is performed to determine the relative prevalence...
