Thank you so much for your reply. So great to hear that you are well, its very encouraging. Did you have any alarming symptoms in your blood work?
Since nothing was found, there must be a reason for this extreme low count of T-cell and the last thing that remain on the list is bone marrow biopsy and genetic exome testing. It could be a mysterious autoimmune condition indeed, but all the main one were negative in the blood work (lupus and rheumatoid arthritis) so was tyroide issues.
I should get the results in maximum 14 days for both the genetic and bone marrow examination.
