What does a low eosinophil ratio mean?

Eosinophils, also known as blood cells, are a component of human white blood cells and, like other granulocytes, originate from hematopoietic stem cells in the bone marrow. Eosinophils play a crucial role in human immunity and allergic reactions, protecting our physical health. During the immune process, eosinophils participate by releasing their contents, thereby causing blockage and damage, and promoting the progression of inflammation. So, what does a low eosinophil ratio mean? Let's answer this question below.

1. What does a low eosinophil ratio mean?

Eosinophils account for only 0.5% to 5% of the total white blood cell count. A generally low eosinophil ratio is commonly seen in conditions such as adrenal cortical hyperfunction, aplastic anemia, acute myocardial infarction, severe burns following major surgery, lobar pneumonia, typhoid, and scarlet fever when severe. The eosinophil count fluctuates throughout the day, and the timing of the test may result in different indicators. Therefore, a single test result does not have significant clinical significance.

2. What are the clinical significance of eosinophils?

Eosinophils typically account for 0.004 to 0.08% of the total white blood cell count. Increases in eosinophil count are generally associated with allergic diseases such as bronchial asthma, urticaria, drug allergies, and allergic purpura. They can also be seen in certain hematologic diseases such as chronic granulocytic leukemia, multiple myeloma, eosinophilic leukemia, lymphoma, and eosinophilic granuloma. The above is a compilation of relevant information on the meaning of a low eosinophil ratio. I hope it helps. If the eosinophil count increases or decreases only once, it cannot be used to determine the specific disease affecting the body. Multiple tests or other examinations are needed to determine the cause.
