How many neutrophils are in the human body?
Understanding the results
Test | Adult normal cell count | Adult normal range (differential) |
---|---|---|
white blood cells (WBC) | 4,300-10,000 (4.3-10.0) white blood cells/mcL | 1% of total blood volume |
neutrophils (ANC) | 1,500-8,000 (1.5-8.0) neutrophils/mcL | 45-75% of total white blood cells |
What do neutrophils do in the body?
Neutrophils are important effector cells in the innate arm of the immune system (Mayadas et al., 2014). They constantly patrol the organism for signs of microbial infections, and when found, these cells quickly respond to trap and kill the invading pathogens.
