Is Low WBC Count A Cause For Concern?

I have a low wbc count of 2.9. Seven months ago, during my routine physical, it was tested at 3.0 and then again at 4.0. It seems to be jumping around the 3 s a lot, but I don t feel particularly bad and have had no real sickness othet than being a bit tired. I just completed another blood test and am awaiting results. Should I be worried?

Hello dear
Understand your concern.
WBC is white blood cell produced by bone marrow.
Protective cell, fight against infection and provide immunity.
So any factor that damage the bone marrow affects its level
Normal count : 3.5-10.5 X 10 9/L

Following are the causes of Low WBC count
Viral infections that temporarily disrupt the work of bone marrow
Cancer that damage bone marrow
Autoimmune disorders
Severe infections that use up white blood cells faster than they can be produced
Medications, such as antibiotics, that destroy white blood cells
Sarcoidosis
Aplastic anemia
Chemotherapy
Radiation therapy
HIV/AIDS
Tuberculosis (and other infectious diseases)
Leukemia
Lupus
Rheumatoid arthritis and other autoimmune disorders
Malnutrition and vitamin deficiencies


Hope this may help you.
Best regards
