I was looking back at my immune labs over the past several years tonight in anticipation of my upcoming phone appt with my specialist. I see the following trends in CDxx cell numbers: Low numbers in the following cell types -- not just slightly low, about 20% below range and steadily declining over the years Total CD3+ CD8+ Total CD5+ OTOH, my CD56+ cell numbers are comparably high. NK cell function has usually been normal. Does anyone else have a similar pattern? Comments?
