Low white blood cell count cause?

Answer 1

A low white blood cell count usually is caused by one of the following:

• Viral infections that temporarily disrupt bone marrow function
• Congenital disorders characterized by diminished bone marrow function
• Cancer or other diseases that damage bone marrow
• Autoimmune disorders that destroy white blood cells or bone marrow cells
• Overwhelming infections that use up white blood cells faster than they can be produced
• Drugs that destroy white blood cells or damage bone marrow

Answer 2

Mildy low white blood cell counts are most often indicative of viral infections (even minor ones, such as the common cold - rhinovirus, and many others).

Answer 3

Anemia is low hemoglobin/red blood cell count. It has nothing to do with the white count.
