However, "-osis" is commonly used in blood disorders to imply cell proliferation (such as in "leukocytosis"), while "-penia" to imply reduced cell numbers (as in "leukopenia"); for these reasons, granulocytopenia is a more etymologically consistent term, and as such, is sometimes preferred to "agranulocytosis" (which can be misinterpreted as ...
Leukopenia (from Greek λευκός (leukos) 'white' and πενία (penia) 'deficiency') is a decrease in the number of leukocytes (WBC). Found in the blood, they are the white blood cells , and are the body's primary defense against an infection .

[5] [6] [7] Other definitions include less than 10 cells/μLiter, while some clinical laboratories classify 0 cells/μLiter as within the acceptable range. [3] The diagnosis of eosinopenia is challenging due to the low number of eosinophils normally present in blood and the fluctuations in eosinophil levels throughout the day.
leukopenia: total white cell count < 4.0 x 10 9 /L. Decrease in all types of white blood cells (revealed by doing a differential count). thrombocytopenia : platelet count < 150×10 9 /L. Treatment
Lymphocytopenia is commonly caused by a recent infection, such as COVID-19. [3]Lymphocytopenia, but not idiopathic CD4+ lymphocytopenia, is associated with corticosteroid use, infections with HIV and other viral, bacterial, and fungal agents, malnutrition, systemic lupus erythematosus, [4] severe stress, [5] intense or prolonged physical exercise (due to cortisol release), [6] rheumatoid ...
Leukocytosis is a condition in which the white cell count is above the normal range in the blood. [1] [2] It is frequently a sign of an inflammatory response, [3] most commonly the result of infection, but may also occur following certain parasitic infections or bone tumors as well as leukemia.
The treatment may mirror that of chemotherapy-induced myelosuppression or may be to change to an alternate drug or to temporarily suspend treatment. Because the bone marrow is the manufacturing center of blood cells, the suppression of bone marrow activity causes a deficiency of blood cells.
