CD4:CD8 Ratio Profile

This test compares the levels of two specific types of white blood cells, called CD4 and CD8 cells, which work together to fight infections. It helps show how well your immune system is balanced and functioning, which is often monitored in conditions like HIV or chronic viral infections. This measurement helps doctors distinguish between a healthy immune response and a weakened or suppressed system. However, this ratio alone cannot diagnose a specific disease or identify the exact cause of an immune imbalance without further testing.
