HHS affirms: Early CDC test kits were delayed because of contamination issues

One of three reagents in the initial batch of test kits was likely contaminated, according to a statement from US Health and Human Services Assistant Secretary for Public Affairs, Michael Caputo, on Saturday.

The contamination was discovered after an investigation was conducted by the HHS Office of the General Counsel at the request of HHS Secretary Alex Azar, the statement said.

“These tests are so sensitive that this contamination could have been caused by a single person walking through an area with positive control material and then later entering an area where tests reagents were being manipulated,” Caputo said.
