CD23

The CD23 test measures the levels of the CD23 protein in your blood. This protein is crucial in regulating the immune response by controlling how immune cells are activated. Monitoring CD23 helps assess your immune system's activity and response to various health conditions.

This test is done primarily:

• To assist in the diagnosis and monitoring of chronic lymphocytic leukaemia (CLL)
• To evaluate CLL treatment effectiveness
• To identify individuals at risk for developing CLL
• To segregate CLL subtypes
• To understand and manage immunological disorders accurately

Doctors suggest the CD23 test for individuals:

• With suspected or confirmed CLL
• Under CLL treatment for therapy monitoring
• With symptoms indicating potential immunological disorders
• With family history predisposing them to CLL
• Requiring separation of different CLL subtypes

• Abnormal results may suggest certain immunological conditions, particularly CLL.
• Elevated levels might indicate an increased risk of CLL or other immune-related disorders.

Discuss any abnormal findings with your doctor for further evaluation and management.

This test requires a blood sample.

During the test:

• A sample is collected using a needle inserted into a vein.
• The process is quick and relatively painless.
• Minimal discomfort might be experienced during blood draw.

There are no specific preparations required for the test. However, it is recommended that you consult with your healthcare provider before taking the test, as they may have specific instructions or recommendations based on your individual medical history and current health status.

Additional tests that may accompany the CD23 test include:

• FISH Testing: Detects genetic abnormalities often seen in CLL.
• Complete Blood Count (CBC): Evaluates overall blood health, important in assessing numerous conditions.
• Flow Cytometry: Identifies various cell types based on their surface markers, useful in diagnosing several cancers and immunological disorders.

• FcεRII Test
• Low-Affinity IgE Receptor Test

Chronic Lymphocytic Leukaemia is a type of cancer originating in the bone marrow affecting white blood cells called lymphocytes. These abnormal cells accumulate, interfering with normal blood cell production and weakening the body's ability to fight infections. Signs and symptoms of this disease include swollen lymph nodes and fatigue.
