Hey LA Twitter - Is there a way to get a Covid 19 test in LA to see if you have the antibodies to help someone else out with a plasma donation? I saw that there would be random testing....I believe I had Covid 19 in late Jan/early Feb and would like to donate plasma. Help?

Thank you, but no need to send me articles/tv segments on LA starting the random testing - I'm asking for a test that I can get because I believe I have the antibodies.
