CD8

CD8 measures the levels of suppressor T cells in the blood. Suppressor T cells help control the immune response, preventing it from becoming too strong. Monitoring CD8 levels can provide insights into how well your immune system is functioning.

This test is done primarily:

• To assess the function of your immune system
• To diagnose or monitor conditions related to immune system abnormalities
• To evaluate treatment effectiveness for certain immune-related disorders

Your healthcare provider may recommend this test:

• If you have suspected autoimmune diseases like lupus or rheumatoid arthritis
• If you are undergoing cancer treatment affecting the immune system
• If you have infections that may be linked to immune system deficiencies

• Abnormal results may suggest autoimmune disorders, immunodeficiency diseases, or cancer.

Abnormal results require further evaluation and discussion with your doctor.

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.

Your doctor may recommend the following tests along with CD8 test:

• Immunoglobulin levels: Measures different types of antibodies in your blood.
• Lymphocyte panel: Evaluates various types of white blood cells involved in the immune response.
• Autoantibody testing: Detects the antibodies which mistakenly targets and attacks the healthy tissues in autoimmune diseases.

• T8 Marker Test 
• Suppressor T Cell Test

Immunodeficiency diseases are conditions where the immune system fails to function adequately, leading to increased susceptibility to infections and illnesses. These diseases result from failure or absence of certain elements of the immune system. These diseases can be primary, due to genetic factors, or secondary, resulting from external factors like HIV/AIDS or chemotherapy.
