My history shows low WBC, but these past 2 times were a little lower then in previous years. Would not eating that morning do anything? (fasting) or maybe even a possible cold? And how do I get my WBC back up?
Low White blood cell count is not a big deal as long as the white blood cells you have are healthy. You can have a high blood cell count but if the cells are malformed then you can be very ill.
Your white blood cell count can vary from day to day because a lot of the specific cells neutrophils, monocytes etc. dart into your tissues and then back into the blood depending on needs of the body for infection protection. So you could draw blood every single day and get a different count higher or lower. Also another thing that matters is percentage of White blood cells and their specific functions. Lymphocyte per centages matter in terms of how many B cells and T cells you have available to fight infection. Neutrophils are very necessary for fighting bacterial infections. Monocytes are also the type of cell that hunts out and swallows up potential bacteria that could cause harm.
There are two illnesses that are specific to low white cell counts the primary known one is AIDS the other is certain lymphomas.
Occasionally the aftermath of flu, or a chronic illness such as Rheumatoid arthritis will cause low White blood cell counts.
