A pathological drop in the total leukocyte count is medically termed_________________?
Show answer Hide answer
Answer: B. Leucopenia
Explanation
Leukopenia is the specific medical term denoting a pathological decrease in circulating leukocytes. It reflects a deficiency in total white blood cell counts below established normal limits. This condition increases patient susceptibility to opportunistic bacterial and viral infections. Leukocytes are essential cellular components of the human immune defense system. Bone marrow suppression or increased peripheral destruction frequently causes marked leukopenia. Complete blood cell counts provide quantitative measurements of circulating leukocyte populations.
Medical practitioners monitor white blood cell levels during chemotherapy and immunosuppressive treatments. Identifying leukopenia prompts investigations into underlying bone marrow disorders or infections. Patients with low leukocyte counts require protective isolation measures to prevent severe sepsis. Leukocytosis describes a pathological increase in circulating white blood cell counts. Leukorrhea refers to a benign whitish vaginal discharge unrelated to leukocyte blood counts. Leukemia represents a malignant neoplastic proliferation of white blood cells in bone marrow.
