A has [wiki2="Chronic"]chronic[/wiki2] low WBC. The doctors didn't even bat an eye until it happened several times consecutively. I started asking about it when I noticed the downward trend, from 8 steady falling to 4. Now they are hanging out at 3.7.
I think you need exact results and low results on consecutive tests before getting too concerned. Is there a reason why you can't get a copy of the labs?
