Ramping Up Rutgers Saliva Testing to Reduce Processing Backlog of COVID-19 Results

To eliminate delays in delivery of results, New Jersey is developing a statewide model for public and private testing

A new milestone has been reached as New Jersey steps up its coronavirus testing program. Doctors at Rutgers University say they can now provide the state with 30,000 tests a day with results available in just 48 hours.

“It says are you positive today or are you negative today. It can be different tomorrow; it can be different yesterday. It’s just one point in time and it says are you positive at that time. It’s important information, but it doesn’t give any more guarantee that you’re not going to be exposed and positive moving forward,” said Brian Strom, chancellor of Rutgers Biomedical and Health Sciences.

The saliva-based coronavirus tests developed at Rutgers RUCDR Infinite Biologics were granted emergency authorization by the U.S. Food and Drug Administration after the state experienced lengthy wait times for test results due to increased outbreaks in other states.

“If somebody gets tested, for example, on a Monday and they’re waiting for their results — and let’s assume they’re negative on Monday — they go out on Tuesday, Wednesday, Thursday, they get their results on Friday. The results say they’re negative. They’re continuing to think they’re negative. It’s entirely possible they may have contracted the disease Tuesday through Thursday,” said Dr. Stephanie Silvera, an epidemiologist and professor at Montclair State University.

Silvera said the lag time between testing and delivery of results allows for the continuing spread of the virus.

“There’s two parts to this: There’s the availability of the tests, which have been ramped up; but there’s the processing of the tests, which is really where the lag seems to be happening and where that bottleneck is. And so it looks like what we need is a bigger investment in our lab capacity to process these tests in a timely matter,” Silvera said.

More testing for New Jersey

To eliminate delays in delivery of test results, New Jersey is developing its own statewide model for public and private testing. For that, $94 million from federal funds in the form of grants will go to hospitals and existing resources to decrease the turnaround time for testing.

“The funding is coming from the CDC,” said New Jersey Department of Health Commissioner Judith Persichilli. “Our hope is that our hospitals will increase their capacity — new equipment, more manpower — and have the ability to rely on ourselves, decrease the turnaround time and reach out into the community, not only doing their own inpatients and outpatients, but reach out into the community and provide testing for our vulnerable populations.”

“The CARES ACT ordered insurance companies to pay for the testing. Insurance companies must pay for it with no deductible. And even people who don’t have insurance, the CARES ACT included money to pay for it. So who’s paying for it? Essentially, the federal government is paying for it,” Strom said.

Both health experts stressed that random testing, while helpful, is not useful unless it’s followed by contact tracing to identify a case and, in turn, prevent the spread of the virus.
