I have done research, but I am making a lot of inferences and I want to be sure I am correct.
1) Does one use ELISA?
2) Does one use serotonin, the patient's blood, and a biomarker to show if / when the antigen and antibody hook up?
And is this done as a medical test in clinic as of yet? So far, I've only seen it within studies.
Thank you for any help you can provide.
