White Blood Cell Differential
What This Test Measures
Breakdown of white blood cell types (neutrophils, lymphocytes, monocytes, eosinophils, basophils)
Conventional vs. Functional Optimal Range
The gap between these ranges is why you feel terrible with "normal" labs. Conventional medicine waits for disease. Functional medicine optimizes for health.
Gabriel's Take
WBC differential is critical. Neutrophilia = bacterial infection. Lymphocytosis = viral infection or leukemia. Eosinophilia = allergies or parasites. Monocytosis = chronic inflammation. Persistently low WBC (under 3.5) deserves a look at B12, folate, copper, viral illness or autoimmunity. Gabriel's optimal WBC is 3.8-6.0 k/μL, with a balanced differential. Gabriel interprets patterns, not just total WBC.
When This Test Is High
High WBC: infection, inflammation, leukemia; High eosinophils: allergies, parasites
When This Test Is Low
Low WBC: immunosuppression, bone marrow issues
Related Conditions
Infections, leukemia, immune dysfunction, allergies
Recommended Follow-Up
Interpret differential patterns: neutrophilia (bacterial infection), lymphocytosis (viral), eosinophilia (allergies/parasites)
