Will eosinophils be elevated during allergy period physical examination

During the allergy period, eosinophils may be elevated during physical examination. Elevated eosinophils are commonly seen in allergic reactions, parasitic infections, and other conditions. If you are in the midst of an allergic attack during a physical examination, the test results may be abnormal. Allergic reactions are one of the common causes of elevated eosinophils. When the human body comes into contact with allergens, the immune system releases inflammatory mediators such as histamine, which stimulates the bone marrow to accelerate the production of eosinophils. These cells will gather at the site of the allergic reaction and participate in the process of combating allergens. If blood is drawn during a physical examination during the acute phase of allergies, the proportion of eosinophils in the blood may significantly increase, manifested as values on the test report exceeding the normal range. This situation is usually accompanied by typical allergic symptoms such as skin itching and sneezing. In rare cases, elevated eosinophils may not be related to allergies. Certain blood system diseases such as eosinophilia and chronic myeloid leukemia can also lead to persistent abnormalities in this indicator. When parasitic infections, especially intestinal worm infections, the body's immune response can also cause an increase in eosinophils. Long term use of glucocorticoids or the presence of adrenal hyperfunction may result in reverse eosinophilia. When an abnormal increase in eosinophils is detected, it is recommended to record recent episodes of allergic symptoms and avoid contact with known allergens. Before rechecking the blood routine, one should maintain a normal daily routine and avoid vigorous exercise. If the indicators remain abnormal or accompanied by symptoms such as weight loss and fever, further investigation of blood diseases or parasitic infections is necessary. Individuals with allergies can inform their doctor of their allergy history in advance before undergoing a physical examination to help accurately interpret the report results.
