Explanation: 

Detailed explanation-1: -A person has leukopenia if they have a reduced number of total white blood cells in their blood. According to the Leukemia & Lymphoma Society, a healthy white blood cell count is 5, 000–10, 000 white cells per microliter (µL) of blood for males and children, and 3, 500–11, 000 white cells per µL for females.

Detailed explanation-2: -A person has leukopenia when the total WBC count is less than 3.0 x 109/L. A person has neutropenia when the ANC is less than 1.9 x 109/L. The neutrophil count usually decreases with the WBC count, but it is possible to have a normal WBC count and still have neutropenia.

Detailed explanation-3: -In general, for adults, a count lower than 3, 500 white blood cells per microliter of blood is considered low.

Detailed explanation-4: -Generally, a count lower than 3, 500 white blood cells per microliter of blood is considered a low white blood cell count. But ask your doctor what the normal range is for the laboratory he or she uses. It may also be helpful to discuss exactly how far outside that range your number falls.

Detailed explanation-5: -Leukopenia is an abnormal reduction of circulating white blood cells, especially the granulocytes. The term leukopenia is often used interchangeably with neutropenia.
