AbbottThere are many reasons to buy Abbott for their different pharmaceutical products but I can't see the reason to buy it for its covid 19 test. The test is useful in ascertaining whether a person has developed antibodies to the coronavirus but that person may not even be contagious anymore. It has some validity but it's most important to find those who are infected and are asymptomatic. Those are the people that may spread the virus if they are not put into quarantine.
