A delay by the federal Centers for Disease Control and Prevention in quickly making coronavirus test kits available was the result of "a glaring scientific breakdown" at the CDC's central lab, The Washington Post reported Saturday, citing scientists and federal regulators.

The Post reported that CDC facilities which assembled the testing kits "violated sound manufacturing practices, resulting in contamination of one of the three test components used in the highly sensitive detection process."

And while the part of the test that was compromised was not critical to detecting the coronavirus, CDC officials took more than a month to remove it from the test kits, according to The Post.

That lag in action aggravated national delays in testing for the virus, and in turn hampered a battle to contain the virus's spread, the newspaper said.

James Le Duc, a virologist and former CDC officer who now heads the Galveston National Laboratory in Texas, told The Post that the situation was "really a terrible black mark on the CDC, and the impact was devastating to the country."
