CD4/CD8 Analysis, Flow Cytometry

This test measures the levels of CD4 and CD8 white blood cells in your body. CD4:CD8 ratio is more useful in the assessment of host the immune function. Monitoring these levels aids in understanding your immune system and detecting issues early.

This analysis is done primarily:

• To monitor immune health in HIV/AIDS patients
• To evaluate immune system status before organ transplants
• To diagnose immunodeficiency disorders
• To assess autoimmune diseases affecting white blood cells
• To track response to cancer treatments, especially for lymphomas

This analysis is usually recommended:

• For HIV/AIDS patients to gauge disease progression
• Pre-transplant patients to assess immune readiness
• For individuals with suspected autoimmune conditions or immunodeficiencies
• Those undergoing cancer treatments
• People with recurrent infections or unexplained illnesses

Abnormal results could indicate:

• Immune system suppression or hyperactivation
• HIV progression or AIDS development
• Autoimmune diseases like lupus or rheumatoid arthritis

Discuss all results with your healthcare provider for accurate interpretation.

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.

Alongside this test, doctors might recommend:

• HIV viral load testing: Measures HIV presence and its impact on the immune system.
• Complete blood count (CBC): Looks for abnormalities in your blood, such as unusually high or low numbers of blood cells and provides overall blood health information.
• Flow cytometry for other markers: Identifies additional immune system cell types for comprehensive assessment.

• Lymphocyte Subset Enumeration by Flow Cytometry 
• T Lymphocyte Panel

HIV i.e. Human Immunodeficiency Virus, attacks the body's immune system, particularly impacting white blood cells like CD4 and leading to Acquired Immunodeficiency Syndrome (AIDS). This condition weakens the body's ability to fight infections and can be life-threatening if untreated.
