CD3/CD4/CD8/CD45

This comprehensive test evaluates specific white blood cells labelled with CD markers to assess the immune system's health. It measures CD3 for T cells, CD4 for helper T cells, CD8 for cytotoxic T cells, and CD45 to identify all leucocytes. These measurements are vital for diagnosing and managing immune-related disorders.

This test is done primarily to:

• Diagnose and manage HIV by monitoring immune function
• Assess immune status post bone marrow transplant
• Evaluate immunodeficiency disorders
• Aid in lymphoma diagnosis and treatment planning
• Identify autoimmune diseases affecting immunity

This test is suggested while:

• Diagnosing or managing HIV
• Assessing immune recovery post-transplant
• Investigating unexplained infections or autoimmune conditions
• Monitoring lymphoma progression or immune deficiencies
• Evaluating therapy effectiveness for autoimmune diseases

• Abnormal results may indicate immunodeficiency, autoimmune diseases, or cancers.

Discuss results with your doctor for further evaluation and treatment planning.

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.

Other tests include:

• HIV viral load testing: Determines the amount of HIV in your blood.
• Complete blood count (CBC): Assesses overall blood health.
• Lymph node biopsy: Examines lymph tissues for cancerous cells or infections.
• Autoantibody tests: Detect antibodies that attack healthy tissues in autoimmune diseases.

• Lymphocyte Subset Panel
• T-Cell Subset Analysis
• Leucocyte Immunophenotyping

HIV (Human Immunodeficiency Virus) belongs to Retroviridae family of viruses. It causes an infection that attacks your immune system’s crucial T-helper cells, compromising your body's ability to fight infections effectively. Two types of HIV have been characterized: HIV-1, and HIV-2. Early detection and treatment are vital to manage HIV effectively.
