Absolute Eosinophil Count (ABEOS)

Price: 4 د.ا

The Absolute Eosinophil Count (ABEOS) test measures the number of eosinophils in the blood. Eosinophils are a type of white blood cell that play a crucial role in the body’s immune response, particularly in fighting off certain infections and in mediating allergic reactions.

Normal Ranges

– Females: 0 to 500 cells per microliter (cells/µL) of blood

– Males: 0 to 500 cells/µL of blood

– Children: 0 to 850 cells/µL of blood

 Function in the Body

Eosinophils are primarily involved in the following functions:

– Combatting Parasites: Eosinophils are critical in the defense against parasitic infections. They release toxins to destroy the parasites.

– Allergic Reactions: They play a significant role in allergic reactions by releasing inflammatory chemicals like histamines.

– Modulating Immune Response: Eosinophils help modulate the immune response by interacting with other immune cells and releasing cytokines.

 Diseases Revealed by the ABEOS Test

Eosinophilia (High Eosinophil Count):

– Allergic diseases (e.g., asthma, hay fever)

– Parasitic infections (e.g., helminth infections)

– Autoimmune diseases (e.g., rheumatoid arthritis)

– Certain cancers (e.g., Hodgkin’s lymphoma)

– Specific drug reaction

Eosinopenia (Low Eosinophil Count):

– Acute infections

– Cushing’s syndrome

– Hyperadrenocorticism

– Steroid use

Symptoms of Eosinophil Deficiency (Eosinopenia)

Eosinopenia itself typically does not cause symptoms but is indicative of other underlying conditions. Symptoms would be related to the primary disease, such as:

– Infections: Fever, fatigue, muscle aches

– Hormonal Imbalances: Weight gain, high blood pressure, mood swings

Symptoms of Eosinophil Overdose (Eosinophilia)

Eosinophilia symptoms depend on the underlying cause but may include:

– Allergic Reactions: Itching, rashes, runny nose, shortness of breath

– Parasitic Infections: Abdominal pain, diarrhea, weight loss

– Joint pain, fatigue, fever

Diagnosis

The diagnosis of eosinophil-related conditions involves:

1. Complete Blood Count (CBC): Measures the overall number of white blood cells, including eosinophils.
2. ABEOS Test: Specifically measures the absolute number of eosinophils in the blood.
3. Additional Tests: Depending on the initial findings, further tests may be necessary, such as:

– Allergy Tests: To determine specific allergic sensitivities.

– Parasitic Tests: Stool tests or serological tests for parasitic infections.

   -Imaging and Biopsies: For more severe conditions like cancers or autoimmune diseases.

– Lifestyle and Management: Managing conditions associated with eosinophil imbalances often involves addressing the underlying cause. This may include avoiding allergens, treating infections, or managing chronic conditions with medication.

– Treatment: Depending on the cause, treatments might include antihistamines for allergies, antiparasitic medications, corticosteroids for autoimmune conditions, or other targeted therapies.

Frequently Asked Questions

Q1: What is the purpose of the ABEOS test?

The ABEOS test helps diagnose conditions that affect eosinophil levels in the blood, such as allergies, parasitic infections, and certain autoimmune diseases.

Q2: How is the ABEOS test performed?

The test is performed through a blood sample, typically taken from a vein in the arm. The sample is then analyzed in a laboratory to determine the eosinophil count.

Q3: Can the eosinophil count change throughout the day?

Yes, eosinophil levels can fluctuate during the day and are typically higher in the evening. They can also be influenced by seasonal changes and other physiological conditions.

Q4: Are there any risks associated with the ABEOS test?

The test involves a standard blood draw, which has minimal risks such as slight pain or bruising at the puncture site.

Q5: What should I do if my eosinophil count is abnormal?

If your eosinophil count is abnormal, your healthcare provider will likely recommend further testing and evaluation to determine the underlying cause and appropriate treatment.

 

Understanding the role of eosinophils and maintaining their balance is crucial for a healthy immune response and overall well-being. If you have concerns about your eosinophil count or related health issues, consult with a healthcare professional for personalized advice and treatment.
