Do any of your kids just" have" this. O's anc runs in 500-900 range but as low as 300 and hasn't been even low normal for a few months now. Her wbc is 3-4 and never above 6. Both only drop with infection....never increase even into normal range. Any thoughts? Concerned that this is causing her frequent line infections. She is always anemic (hgb 8-10) and her platelets fluctuate between 100-150 so not terrible but often below normal.
