In patients with pneumonia, high total white blood cell count, elevated neutrophil count, and elevated neutrophil ratio are usually seen in blood tests. Bacterial pneumonia is an acute inflammation of the lung tissue caused by bacterial infection. If the pneumonia is caused by a viral infection, the blood work is often normal, or there is a lower white blood cell count, high lymphocyte count, and an elevated lymphocyte ratio. Therefore, which indicators of blood count are elevated in patients with pneumonia depends mainly on the specific type of pneumonia, as well as on individual differences.
