What WBC Numbers Really Mean
- White blood cell (WBC) count is shown as WBC and normally ranges roughly 3–10 on blood work. Dr. Stephen Cabral prefers a functionally healthy range not below about 4 and cautions that values reflect immune activation, not a single definitive diagnosis.
Bone Marrow And Serious Causes
- Bone marrow suppression from chemo, radiation, or certain immunosuppressant drugs can cause low WBCs and must be taken seriously. Cancer itself can also present with low white blood cells, so clinicians should investigate context and other markers.
Always Interpret Labs In Context
- Do not read any single blood marker in isolation; evaluate autoimmune markers like RA factor, ANA, and TPO alongside WBC. Check for signs of autoimmune disease (e.g., lupus, rheumatoid arthritis, Hashimoto's) when WBCs are low.
