Okay, deep breaths!!! You'll be okay.
First off, your doctor shouldn't have told you that you can't have lupus with a negative ANA. You definitely CAN have lupus. Is this your rheumatologist who told you that, or your primary doctor?
It is urgent to find out the cause of why you have a low WBC count. I have chronic low WBC counts. It's called Leukopenia. Very common in lupus. I don't have enough WBC to fight infections properly. Mine fluctuates between normal and low all the time. I just have to be extra careful around people who are sick, I wash my hands a lot and stay away from situations that might make me sick.
If you can get to the lab on Friday, one extra day isn't going to change anything. Let us know what comes of the test okay?
I can do anything through Jesus Christ who strengthens me. I have learned in whatever state I am in,to be content. Phillipians 4:11-13
