Detailed explanation-1: -White blood cells, also known as leukocytes, are responsible for protecting your body from infection. As part of your immune system, white blood cells circulate in your blood and respond to injury or illness.
Detailed explanation-2: -Leukocytosis is the broad term for an elevated white blood cell (WBC) count, typically above 11.0x10^9/L, on a peripheral blood smear collection. The exact value of WBC elevation can vary slightly between laboratories depending on their ‘upper limits of normal’ as identified by their reference ranges.
Detailed explanation-3: -Definition. Leukocytosis is an elevation in the absolute WBC count (>10, 000 cells/L). Leukopenia is a reduction in the WBC count (<3500 cells/L).
Detailed explanation-4: -The reference range for adults (males and females) is as follows : Total leukocytes (adults and children >2 years)-5000-10, 000/mm. Total leukocytes (children aged 2 years or below)-6200-17, 000/mm. Total leukocytes (neonates)-9000-30, 000/mm.
