Is 1.2 low for a white blood cell count?

Yes. A normal white blood cell count for adults ranges from 4,000 to 11,000 white blood cells per microliter of blood, so 1.2 is quite low. A low white blood cell count can indicate a variety of underlying conditions, such as an infection, autoimmune disease, or bone marrow disorder. It is important to see a doctor if you have a low white blood cell count to determine the cause and receive appropriate treatment.
