According to the CDC[1], you can contact your healthcare provider for the possibility of a test if (and only if) you are in close contact with someone with the disease or if you're in a community where there's ongoing spread. That's still a very limited subset of people who might have the disease.
There's very limited insight into who does or does not have the disease in the US.

That said, we must manufacture medical equipment for pandemics locally or have a reserve like oil.
One of them said a few days ago masks and other supplies were stolen from a delivery truck that was broken into as the driver went in to start the delivery to the hospital.
My sense is there's a lot of leakiness in supply of various forms.
My experience is similar to those of others here: it's not really clear there's a substantial increased patient count at the hospitals here, test or not, but supplies are getting scarcer. Maybe other areas of the country or world are creating shortages.
Testing is a mess, but that's a different issue, one maybe more relevant to public health and policies in some ways.
