After further investigation I found out that only the percentage of my Lymphocytes where high and the abs. number was normal.
BUT It's because my abs. number and the percentage of Neutrophils were low.
I'll try to summarize my WBC - White Blood Count (Before I suffered from BO vs. today):
Neutrophils (%) - decreased from 60% to 40%.
Neutrophils (abs. count) - decreased from 3.9K/ul to 2.5K/ul.
Lymphocytes (%) - increased from 36% to 45%.
Lymphocytes (abs. count) - increased from 2.4K/ul to 3.3K/ul.
Monocytes (% and abs. count) - Increased.
Basophils (% and abs. count) - Increased.
Eosinophils (% and abs. count) - Minor increment.
Note that the results above doesn't exceed the normal range.
It's important to say that this results stayed almost constant in the past 3 years (I got this BO for almost 5 years).
I wonder why my Neutrophils decreased while my Lymphocytes, Monocytes, Basophils and Eosinophils increased. and how it's connected (or not) to LGS. Any ideas?
