Introduction
An eosinophil count of 0.61 usually refers to eosinophils accounting for 0.61% of the total white blood cell count. This value is slightly above the normal range and may indicate conditions such as drug reactions, allergic reactions, urticaria, parasitic infections, or psoriasis. Patients are advised to seek medical attention promptly. Additionally, this elevation could also be caused by eosinophilic leukemia.

Under normal circumstances, an eosinophil count of 0.61 usually refers to eosinophils accounting for 0.61% of the total white blood cell count. This value is slightly higher than the normal range and may indicate conditions such as drug reactions, allergic reactions, urticaria, parasitic infections, psoriasis, or other causes. Patients are advised to seek medical attention promptly. Specific analyses are as follows:

1. Drug Reactions

Certain medications may cause side effects leading to increased eosinophil counts. Examples include antibiotics and antifungal drugs. Patients should consult their doctor to adjust dosages or switch medications.

2. Allergic Reactions

When the body is allergic to certain foods, medications, or environmental factors, the immune system releases eosinophils to combat allergens, which may result in elevated eosinophil counts. Patients experiencing allergic reactions should follow medical advice and take antihistamines such as loratadine tablets, epinastine hydrochloride tablets, or cetirizine hydrochloride tablets.

3. Urticaria (Hives)

Urticaria is characterized by red or pale wheals on the skin, accompanied by symptoms such as itching, swelling, and stinging pain. These symptoms are primarily caused by mast cells releasing inflammatory mediators like histamine. Eosinophils play a role in phagocytizing these inflammatory mediators, thus leading to increased eosinophil counts in urticaria. Patients may apply tacrolimus ointment, zinc oxide ointment, or calamine lotion as directed by a physician.

4. Parasitic Infections

Following parasitic infection, the body's immune system mounts a response. Eosinophils, as important immune cells, can kill parasites or inhibit their proliferation by releasing eosinophilic granules. This may lead to elevated eosinophil counts. Treatment under medical guidance may include mebendazole tablets, albendazole tablets, or cefixime dispersible tablets.

5. Psoriasis

Psoriasis may increase eosinophil counts in the skin, which is reflected in blood tests as elevated eosinophil levels. It is recommended to follow medical advice and use medications such as calcipotriol ointment, tacalcitol ointment, or tazarotene gel to alleviate symptoms.

In addition, elevated eosinophil counts may also be caused by eosinophilic leukemia. Patients should actively cooperate with their doctors for treatment, which will aid in recovery.
