My immunologist ordered some T-Cell blood tests and some of them were abnormal. My CD4/CD8 Ratio is High (5) CD3/CD8 Absolute Count is Low (<250) Please, does anyone know what my tests mean? I have attached my test results to this question. I am a female in my 60's and have been ill for years, with no diagnosis. I feel sick and ill, with severe ongoing daily fatigue. My muscles (in my legs and arms) will ache when I use my muscles, and this makes difficult for me to walk too long. Sometimes I am so tired I fall asleep during the day for short times (about 30 minutes) and wake up feeling a little less tired. I have trouble thinking, because I can not remember things quickly anymore.
