Yes. A few months ago they talked about using it for COVID19 at universities in America and probably some work places. I assume they are doing it. It sounded like that was the plan when I saw interviews discussing it.

Yes. We’re not doing it yet, but it’s a viable method of testing.

It is a brilliant idea. Some labs are experimenting now using sewage as the test sample. Theoretically they can take a sample from a dormitory wing or floor and use that as a quick test to decide if further testing is required.
False negatives are a problem today but I have confidence in the system.

As long as a testing method is effective, we should use it. We need to collect as much data, as possible.

I thought that we had been doing this for months. At least they were taking about it several months back and it sounded as though it had been put into use so the tests would come back faster

lf tests to determine who in that batch actually had the virus came back negative then every person in the batch tested received a notification of negative results However, if the tests came back positive,then each person in the batch went through another test to determine who actually tested positive

@SEKA , The system is set up so that if the tests come back positive, they know whose sample it was. Each person has a sample in six of the pools. The group of six is unique for each person. The system can also handle cases where a few people test positive. I wish I could say more, but I don’t know the specifics.

Yes, I heard about it earlier in the pandemic. Practical math applications are really interesting and satisfying.
