Here is the response I received today from Jane at Stanford, with her permission to repost:
The testing for the study is ongoing. We are doing 3 types of pathogen tests
as well as multiple immunology tests and gene expression tests. We don't
have results as yet. When we do we will contact you. I know it's been a long
time, but I think we are finding out some things about the disease that will
help in the long run. Thank you for your participation.
