UK is way ahead of USA, I am quoting @kevin99 post in its entirety:
"I’ve received a reply from Oxford Uni today, I mentioned I would like to post it on here, which they were happy with as long as I didn’t include the details of their researcher, who then may be inundated with emails, so here it is:
Thank you for your email, and I am so sorry for the delay in reply. We have received a lot of interest since the BBC special aired!
We are recruiting people with psychosis, aged 18-70 years for our study to test for antibodies in patients with psychosis. For participants to be eligible for the study, the current episode of psychosis should be for less than 2 years, but that can be a first episode, or a relapse. We are currently recruiting from South London and Maudsley Trust for this study. Our recruiter in SLaM is xxxxxxx and he can be contacted on: xxxxxxxxxxxx. He will be able to determine whether or not your wife is eligible to participate in the study.
If your wife does not meet study eligibility criteria, then your clinician (GP/psychiatrist) can request the antibodies blood test anyway, through clinical routes. I know this is sometimes done in SLaM.
The particular antibodies we recommend they test for are NMDAR -live assay, LGI1. The details for how clinicians can request the test, and the request card to use are here:

I hope this information is helpful, please feel free to get in touch if you have any further questions.
Looks like my wife won’t be eligible, but will check directly with the Maudsley next week, and then go to local GP for the test if necessary. If anyone out there manages to get on this study, or have the test done, please keep us updated.
They have requested that any enquiries go to the firstname.lastname@example.org address"
