Basophils are the least common type of white blood cell. They play a key role in the immune system's response to allergens and parasites by releasing histamine and heparin. Within a Differential Count (TCDC), basophil levels are monitored to detect chronic inflammation or rare bone marrow disorders. While their exact function is still being studied, they are essential markers for type I hypersensitivity reactions.

Why Context Matters
Basophil counts are naturally very low; automated counters can sometimes misidentify other cells as basophils. Persistent elevation (basophilia) is a significant 'red flag' that often requires manual slide review to rule out myeloproliferative neoplasms.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
