If my WBC goes below 3.0 my LLMD takes me off everything. It went down to 2.3 and 2.6 in March and April and he immediately stopped all my abx. It took almost 3 weeks for it to get above 3.0 again. He also wanted me to stay away from crowds because he said I was at high risk for infection and if that happened he told me it could be life threatening.
I work in retail so had to take a few weeks off. I have always been in the low 3.0's since becoming sick. I have mine tested every month or if it gets into the 2.0's every two weeks. Hope this helps.
