COVID tests are completely random. They are engineered to randomly give a result that matches the required number of cases.
For example, if the testing place is instructed that the number of new COVID cases they are to find is 250, and they have 10,000 people come in that day, test results will be adjusted to 2.5% positive rate, chosen randomly.
