There is not enough testing capacity, so tests are being done where they can do the most good such as testing at hospitals, to determine treatment, or whether a person needs to isolate to keep from spreading the virus. The U.S. will eventually need to go to random testing(maybe 10% of the population) to get a handle on the pandemic but it's a hard test to administer, it also needs to be done regularly, and it costs over $50 per test, so widespread testing will be hard.
