CD103

CD103 measurement aids in assessing the presence and activity of regulatory T cells. These cells play a key role in immune system regulation, preventing excessive immune responses that can lead to autoimmune diseases or allergic reactions.

The CD103 test is done to:

• Evaluate the functionality of regulatory T cells.
• Diagnose autoimmune disorders.
• Monitor treatment effectiveness for immune-related conditions.
• Understand allergic responses.
• Identify certain types of cancers like Hairy Cell Leukemia.

Doctors recommend this test to:

• Evaluate autoimmune disorders.
• Assess immune system health post-treatment.
• Investigate allergic reactions.
• Diagnose Hairy Cell Leukemia.
• Monitor immune system function in specific patient groups.

If the results of a CD103 test are abnormal, it could indicate several possibilities depending on the specific context:

• Normal range: Results vary; consult your healthcare provider for accurate interpretation.
• Abnormal range: May suggest immune dysregulation, autoimmune disorders, or certain cancers.
• Alterations in CD103 could also be indicative of an ongoing infection.
• Follow-up tests may be required.
• However, you should discuss the results with your doctor for a clear understanding and further action.

You will provide a blood sample in a minimally invasive process:

• Collection via venipuncture
• Minimal discomfort expected during blood draw
• Quick and simple procedure at any pathology lab

You can prepare for the test by:

• Informing your health provider about medications.
• Ensuring adequate hydration before sample collection.

Other tests alongside CD103 may include:

• Regulatory T Cell Panel: Evaluates various markers on regulatory T cells.
• Flow Cytometry: Provides detailed analysis of cell populations in blood samples.
• Hairy Cell Panel: Focuses on detecting markers for Hairy Cell Leukemia diagnosis.

Integrin Alpha E (or ITGAE) or Cluster of Differentiation 103

Hairy Cell Leukemia (HCL) is a rare, chronic blood cancer that occurs when the bone marrow produces too many abnormal B lymphocytes, a type of white blood cell. This can lead to low blood counts, which can lead to infections, fatigue and bleeding problems. Treatment is designed to effectively control symptoms and prevent complications. The name comes from the microscopic appearance of leukemia cells, which have small hair-like projections on their surface.
