Plasma taken from the blood of recovered COVID-19 patients stands a real chance of being one of the more effective short-term measures feasible in the ongoing effort to control the global coronavirus pandemic. The FDA has issued a broad call for donations from eligible individuals, and now Microsoft has built an online screening tool on behalf of the CoVIg-19 Plasma Alliance (which is funded in part by the Bill and Melinda Gates Foundation).

The “CoVIg-19 Plasma Bot” that Microsoft created for the foundation is just the latest COVID-19-related bot built by Microsoft using its technology, and its symptom self-checker for the CDC was one of the earliest large-scale efforts of its kind in the U.S. The Plasma Bot takes you through a series of simple questions to determine your eligibility, from the perspective of both your ability to meet the actual biological and health requirements, to your willingness and a ability to participate in the plasma collection process itself at a donation center.
