What Could Cause an Elevated Percentage of Eosinophils in a Blood Routine Test?

An elevated percentage of eosinophils in blood routine tests is often associated with eczema, but it may also be caused by urticaria, schistosomiasis, bronchial asthma, and other reasons. It is recommended to adopt appropriate treatment methods after diagnosis.

1. Eczema

Exposure to irritant substances and genetic factors can often lead to autoimmune abnormalities, accompanied by inflammation in the superficial dermis and epidermis. Common symptoms include redness, swelling, and itching. Clinical examination may reveal an abnormal percentage of eosinophils. It is recommended that patients consult a doctor for further examination and treatment. Medications such as loratadine capsules, prednisone acetate tablets, and tacrolimus ointment may be prescribed under the guidance of a doctor. In addition, patients should take good care of their skin and maintain healthy habits.

2. Urticaria

Bacterial infections, emotional fluctuations, and autoimmune diseases can often lead to the dilation of small blood vessels in the skin and mucosa, resulting in local edema, wheals, and other symptoms. Blood routine tests may show an elevated percentage of eosinophils. Patients may be prescribed medications such as cetirizine hydrochloride capsules, dexamethasone acetate tablets, and omalizumab injection under the guidance of a doctor to alleviate symptoms caused by urticaria. It is important to closely monitor the progress of treatment, rest adequately, and exercise regularly.

3. Schistosomiasis

Poor living conditions, unsanitary personal hygiene, and environmental pollution can often lead to the growth and reproduction of schistosomes. If proper care is not taken, direct contact may induce schistosomiasis infection. Blood tests may reveal a significantly higher percentage of eosinophils than normal. Treatment with drugs such as artesunate piperaquine tablets, compound dihydroartemisinin tablets, and artesunate amodiaquine tablets can eliminate schistosomes under the guidance of a doctor. It is important to maintain personal hygiene and eat a healthy diet.

4. Bronchial Asthma

Genetic factors, inhalation of specific substances such as pollen, and respiratory infections can often lead to chronic inflammation of the airways, accompanied by symptoms such as chest tightness and shortness of breath due to airflow obstruction. Blood tests may reveal abnormal indicators. Medications such as montelukast sodium tablets, theophylline sustained-release tablets, and salbutamol aerosol may be prescribed under the guidance of a doctor to relieve asthma symptoms. It is important to avoid exposure to allergic substances and regularly clean the living environment.

Apart from the above reasons, the elevated percentage of eosinophils may also be caused by allergic purpura, which is often associated with parasitic infections, drug allergies, food allergies, and other reasons. This can lead to dysfunction of the immune system and allergic inflammation. Patients may be prescribed medications such as acetaminophen tablets, cyclophosphamide tablets, and azathioprine tablets under the guidance of a doctor to suppress inflammatory reactions. Regular hospital visits and attention to personal and dietary hygiene are also recommended.
