So great that he's enrolled! Will be really interested to hear his result. I'd love to have S participate but seems to be a US study only (will look around to see if there's an equivalent Cdn. study).
I did speak with a company here which runs the spike antibody test (for natural and/or vaccine antibodies) but they have a warning that results may be skewed with immune-compromised patients. Were you, or Lisa, given any info regarding this?
The test available here does give a value, rather than just a positive/negative result (thanks Lisa for bringing this up).
If S's number is low, I'd love for him to get a booster somehow... he has a follow-up to his recent tests soon, so I've asked him to ask his GI what his thoughts are on this. I know Cda isn't give booster shots yet but... IDK... maybe I can find a way with my will!
