Leukocyte formula - the percentage ratio of different types of leukocytes in the blood smear. When evaluating the leukocyte formula, it may be necessary to take into account the absolute content of certain types of leukocytes.
Changes in the leukocyte formula accompany many diseases and are often nonspecific. Nevertheless, the diagnostic value of this study is great, as it gives an idea of the severity of the patient's condition, the effectiveness of the treatment. With hemoblastoses, the study of the leukocyte formula often allows you to establish a clinical diagnosis.
