A critical low white blood cell (WBC) count, also known as leukopenia, is generally considered to be less than 4,000 cells per microliter of blood. This level indicates a significantly increased risk of infection.
Understanding Low WBC Count
A low WBC count means the body has fewer infection-fighting cells than normal. According to the provided reference, when you don't have enough white blood cells, especially neutrophils, you're more vulnerable to infections.
Implications of a Critically Low WBC Count
- Increased Infection Risk: The primary concern with a low WBC count is the higher susceptibility to bacterial, viral, and fungal infections.
- Delayed Healing: The body's ability to repair damaged tissues and fight off infections is compromised.
- Severity Varies: The lower the WBC count, the greater the risk and severity of potential infections.
Factors Affecting WBC Count
Various factors can influence WBC counts, and what constitutes a "critical" level may vary slightly depending on the laboratory and the individual's overall health.
