But you haven´t post the number of the count !!!
First thing to do is to repeat the test after one week . And go to blood test after eat a light meal , empty stomach also can make a little lower count of leucocytes.
Anyway , no reason to worry, roids just don´t have any relationship with low count of leucocytes .
There are a lot of couses (being sick is just one) .
keep me posted.
