Hello, welcome to HCM.
Firstly, you do not need to increase the monocyte
count. Basically we find Monocyte as 1-3%. So, usually the level is very low. But, this report should be corroborated with the peripheral blood findings.
Secondly, decreased monocyte count does not indicates an infection. Rather its increased number indicates a chance of leukemia
There is nothing that can help you to increase its number.
So, do not worry.
