About a year ago Fiona's t cell function dropped. We just got her antigen test back. Her pha stimulation result is 5682, normal is >=135190. That means that when her t cells are stimulated with a chemical called phytohaemagglutinin, they don't respond properly. Her Candida and tetanus responses are low too.
She is over RSV, which is amazing. I was worried about her cough, then it was gone. Igg replacement is working. Now if they could figure out a way to fix her t cells she would be in great shape.
