Great news for those guys in Texas, but really how many helmet ventilators can they make and get to ICUs in two weeks? Because that's when their ventilator stock gets depleted in Texas (and every nearby state where people went to Mardi Gras).

We need those antibody tests and we need them right now, by the millions. Here's why: People with antibodies who have had no symptoms or recovered a few weeks from mild symptoms can go back to work, getting a start on reviving the economy and filling in for all the people sick or in quarantine. They can also donate antibodies to give besieged health care workers some protection. Blood banks need to start offering those with antibodies a suitable bounty ($500?) for donating one unit of blood. If they test and then centrifuge that blood, it is very easy to separate out the plasma from the red cells. They desperately need the red cells for transfusions, but they can also purify Covid-19 antiserum from the plasma. This antiserum can give passive immunity to people that receive it. In particular, health care workers who are inevitably going to be exposed at work. You don't have to give it to health care workers who already have antibodies, which is another reason we need those tests.
