and to an urgent push to treat the most severe coronavirus patients. Diane sawyer has an inside look at a procedure, using the anti-bodies of those that already recovered. It's going take time, but the country's top infectious disease expert Dr. Anthony Fauci already indicated anti-bodies could be a key part of this fight. Here's Diane reporting like so many tonight, from home. Reporter: It's an experimental treatment, and possibly hope for those hospitalized by the illness until better treatments or a vaccine are within reach. Am I right of an anti-bodies of a recoverying person can save the life of someone who is critically ill? That is concept, Diane. If you give the plasma, the portion of the blood that contains the antibodies, from someone recovering from an illness, a viral illness like covid-19 or ebola -- it may help the patient overcome the disease. And so our plan is to infuse this into patients with moderate to severe illness who are in our hospital. Reporter: They are hoping to start with just one case this weekend. And hoping that among the people on their list to donate blood are, in fact, super donors who may have particularly high levels of anti-bodies. They tell us one donor could end up helping more than one patient. We have developed a test here at mt. Sinai to look for community anti-body responses to covid-19. Reporter: This is professor Florian Krammer and his dedicated lab team who have made breakthroughs working nonstop. He sent ABC news this video. In these small wells, antibodies are reacting. The more intense the yellow color, the more antibodies from the donor. Will some people in this country be super anti-bodies? Super immunizers? Everyone who recovers from an illness like this will develop some degree of immunity. Reporter: The nation's expert, Dr. Anthony Fauci, also wants to see if this can work. It's one of our top priorities. Reporter: Already the hospital has received thousands of offers to donate. But they tell us every donor has to have a documented positive test and be at least 21 days from their first symptoms. I think that it's beautiful if people who are recovering from the illness can, in the spirit of donation and helping others, that some of them will have that capacity by having very high levels of immunity. Reporter: Among the perspective donors who wrote in is a 31-year-old lawyer. Had a very high fever. Reporter: He tells us he recovered two weeks ago. If I have a resistance to it that can then be help to someone who's elderly or someone who's sick, I would be honored to do that in any way that I can. Reporter: And late last night, he sent us a video of the moment he got news back from the team at mt. Sinai. It says, you may be able to help. Reporter: David wanted to send a message that of course we don't know what the outcomes will be, but we know doctors and scientist across the country are working on this. As soon as there are results we'll be back in touch. Look forward to it Diane. Diane will stay on this. When we come back here, the
