@curiousanne Actually, testing capacity is part of the dilemma we face at this point. The availability of tests in most places is extremely limited, and it will be some months before production will ramp up to the point where everyone who should be tested, or wants to be, will be able to get a test, whether for active virus or antibodies.
The second complication is the number of unreviewed, unproven post-tests that have been tushed to the market. Many have been shown to give dubious results, and a false positive could give a false feeling of security, and cause people to be endangered.
Finally, there is more work to be done to confirm that presence of antibodies confers immunity to further infection.
So for now, the best policy is continued self isolation as possible, infection precautions, and staying as healthy as possible.
