More than 130,000 Americans have been tested for coronavirus as kits are sent out and drive-thru centers pop up across the US.

As of Friday afternoon, 12 percent have been confirmed positive and the results of about 3,300 tests are still pending.

It's a welcome surprise after weeks of delays from federal health officials and red tape in authorizing outside labs to perform tests.

Several states have since ramped up testing including opening drive-thru centers and even offering testing at some places without appointments.

There was great difficulty in getting tested in the early days of the outbreak due to health officials first distributing a flawed test, then only providing states with a couple hundred each.

The Centers for Disease (CDC) shipped its first batch of kits to laboratories across the US on February 5.

Less that a week later, several state labs said the CDC diagnostic was returning 'inconclusive results.'

This forced the federal health agency to remanufacture components of the kit, although its unclear what defect occurred.

By March 6, an investigation from The Atlantic found only 1,895 people had been definitively been tested for coronavirus.

That same week, US Food and Drug Administration (FDA) Commissioner Stephen Hahn said upwards of a million tests would be performed by the end of the week.

But officials within the Trump administration later had to come forward and admit the government had nowhere near that number of kits readily available.

Health and Human Services Secretary Alex Azar explained during a press briefing on that each suspected person actually requires two tests.

Therefore, even if one million tests were run, only 500,000 patients at most would be tested - and that's if no tests return inconclusive results.

Since then, several states have ramped up testing in an attempt to more quickly identify and isolate infected people before they spread the virus.

New York has performed the most with more than 32,000 tests completed followed by Washington, California, Texas and Minnesota, respectively.

Several states have opened clinics where appointments can be made, drive-thru testing locations, and even a few sites where no appointments are necessary.

These are the numbers of tests that have been run by every state and territory:
