I agree with Ramon. I've heard if you had a low CD 4 when you were diagnosed, it takes a bit longer to get it back to normal values with the meds. Sounds like you have, Good for you. Adhere to your meds and you should be able to maintain your counts. Remember HIV/AIDS is different with every individual. Take care of yourself.

All of us have a compromise immune system even me and my cd4 is 727. Undetectable is awesome and extremely important great job keep up the good work

Your immune system is not compromised if you are undetecable it is not 100% you need to do everything you can to be active and healthy. Make sure you do not miss a dose of meds and avoid unhealthy crap like recreational drugs and alcohol to excess. eat healthy and excersise..

I also went down to 2 never got sick and now have climbed to 100 been under 200 for many years but undetected.. healthy man of 57 don’t think they will ever go back up

I'm undetectable but have always had a low cd4. Problem is we usually don't have a baseline to what it was before infection. It may have always been low but even then should get up over 100
