What are White Blood Cells (WBC)? White Blood Cells (WBC), or leukocytes, are a critical component of the immune system, responsible for fighting infections and foreign invaders. They include subtypes like neutrophils, lymphocytes, monocytes, eosinophils, and basophils. Measuring WBC count in the blood is a key part of a complete blood count (CBC) and helps diagnose infections, inflammation, hematologic disorders, and immune system conditions.
Definition: The White Blood Cells Unit Converter converts WBC counts between various units, enabling standardization of laboratory results for clinical use.
Purpose: It assists clinicians and researchers in interpreting WBC counts across different measurement units (e.g., 10^9/L to K/µL), ensuring accurate diagnosis and monitoring of immune and hematologic conditions.
Converting WBC counts between units is critical for:
Elevated Levels (Leukocytosis): High WBC counts may indicate infections, inflammation, stress, leukemia, or tissue damage. Specific subtypes (e.g., neutrophils, lymphocytes) provide further diagnostic clues.
Low Levels (Leukopenia): Low WBC counts may suggest bone marrow suppression, viral infections, autoimmune disorders, or chemotherapy effects.

Interferences:
Q: Why are there different units for WBC counts?
A: Different units reflect varying standards; 10^9/L is the SI unit, while K/µL and cells/µL are commonly used in clinical practice, particularly in different regions.
Q: What is a normal WBC count?
A: Normal WBC count is typically 4.0–11.0 × 10^9/L (4.0–11.0 K/µL). Ranges vary by age and lab—consult a healthcare provider for interpretation.
Q: Can this converter be used for other blood cell counts?
A: No, this converter is specific to WBC counts; other blood cell counts (e.g., RBC, platelets) have different units and conversion factors—consult a healthcare provider for accuracy.
