Can Wilabrands runs in my family with levels around 27% with the exception of my uncle who had less than 1%. No one in my family, including myself, who have levels normally at 27% have had a decrease like this. On occasion our levels have risen. So I am a little out of my element. What does this mean and what could have caused it? I haven't gotten in touch with his HTC Dr yet but spoke to the nurse. Is there anything I should be concerned with and bring up with her also? Thank you
