Kathy Griffin is in COVID-19 isolation at the hospital.
The 59-year-old, who is now in a hospital isolation ward room receiving treatment, said she still couldn't get tested because of CDC restrictions.
NPR reported that the United States had surpassed South Korea in coronavirus tests, but added that the latter surpassed the U.S.in per capita testing.
Griffin tweeted that she had not been tested because of administration restrictions.
Hours earlier, President Trump had tweeted that the USA had done "far more "testing" than any other nation, by far!"
As of Wednesday, the latest data from the official COVID Tracking Project claims there have been 484,062 tests done (and counting) in the USA, with 65,497 coming out positive.
"Clinicians should use their judgment to determine if a patient has signs and symptoms compatible with COVID-19 and whether the patient should be tested."
