Morning,
The white blood cells r ur immune system n the big generals, we can call them, r ur IgG, IgM, IgA. These “generals” tell all the monocytes, lymphocytes etc what to do...when these generals r not working properly, infection is eminent. IgG is the most prevalent general (protein) in ur body, IgA is in ur respiratory tract n lining of ur lungs as is IgM. When these don’t work properly, u have to have the IgG either IV or in ur belly (sub q). I have a port in my chest now which makes life much easier!
