Do you have low white blood cells with lupus?

Leukopenia and neutropenia are very common in active lupus, but rarely are white cell counts low enough to lead to infection. Counts may be lowered by azathioprine, cyclophosphamide and some other drugs. Therefore, white cell counts are always monitored during treatment with these agents.
