Missouri coronavirus saliva test approved by FDA

Gov. Mike Parson announced Wednesday that a saliva test from Washington University in St. Louis has been approved, the new test requiring less person-to-person interaction and proving to be cheaper overall compared to the swab test.

COLUMBIA, Mo. (AP) — A Washington University saliva test for the coronavirus has been approved by the Food and Drug Administration (FDA), Missouri Gov. Mike Parson announced Wednesday.

The St. Louis-area university worked with biotechnology company Fluidigm to develop the test, which allows people to collect their own testing samples by spitting into small tubes. Test results are available in a few hours.

The FDA gave Fluidigm emergency approval for the test, which also allows Washington University School of Medicine to start using it, according to a release from the school.

The test removes the need for health care workers to swab deep inside noses, Jeffrey Milbrandt, who heads Washington University School of Medicine’s McDonnell Genome Institute, said in a statement. It also doesn’t require RNA extraction kits, which Milbrandt said makes the tests cheaper.

“People can collect the sample themselves, and it doesn’t require an uncomfortable nasal swab,” Milbrandt said. “Another problem with current testing is the shortage of certain lab supplies that are required to process viral samples. We have developed a method to process the saliva samples that doesn’t require these specialized supplies.”

Meanwhile, Missouri’s state health director said he won’t follow new recommendations by U.S. officials against testing people who have been in close contact with infected people.

The new guidance was posted earlier this week on the website of the Centers for Disease Control and Prevention.

The agency previously advised testing for close contacts, but on Monday that was changed to say that testing is no longer recommended for symptom-less people who were within 6 feet of an infected person for more than 15 minutes.

Missouri health department Director Randall Williams on Wednesday said he doesn’t understand why U.S. health officials shifted gears on testing and has been trying to get more information.

“At this point in time, barring something I learn that I don’t know yet, that would not be the direction I’d recommend Missouri go,” Williams said.

Williams said unless he’s presented with “clear evidence” to the contrary, he still encourages Missourians to get tested if needed and as recommended by their doctors.

Parson’s administration has pushed for increased testing as part of the governor’s reopening plan.
