What does it mean when someone has a high mature CD3 %,
The results state mature CD3 84%. In range is 57%-85% therefore nearly as a clinical lymphocytosis.
My questions kindly, what is the most common reason for this reading?
Is a high CD3% (mature T) a bad indicator?
I would say, it basically means that you have a good immune system as CD3 is expressed in mature T cells which help in T-cell related immunity. They originate from thymus. In your case it is still within range. However, do ask your doctor about it also. Take care!
