CD4 cells help the body fight infections. CD8 cells help fight cancer and germs that live inside your cells. The CD4:CD8 ratio test judges the strength of your immune system. It also tells your physician if you are at risk for opportunistic infections like pneumocystis pneumonia. Your physician may want to protect you by prescribing some medicines.

My last CD4:CD8 test result in Nov23 was 0.79.

yep. I might be wrong. Me and my dr went over this. I know she said that's a marker for having HIV. My cd4 is in the high 600's low 700's and I still have a low cd4% We have more cd8 than cd4 cells.

Hope it helps…
