A low neutrophil ratio refers to a decrease in the percentage of neutrophils in the overall white blood cells, which may be associated with certain infections, blood disorders, and physicochemical factors of injury.
Neutrophils are a type of leukocytes, which also include lymphocytes, eosinophils, basophils, and monocytes, so the neutrophil ratio refers to the percentage of neutrophils in the leukocyte population, and a low neutrophil ratio is indicative of a decrease in that percentage.
Low neutrophil ratio may be related to typhoid and paratyphoid infections, blood disorders such as aplastic anemia, and physicochemical damage such as X-rays and benzene.
When neutrophil ratio is low, the cause needs to be clarified under the guidance of a doctor so that it can be treated aggressively.
