State provider Curative moves to Abbott nasal Covid-19 test Reading Time: 2 minutes Beginning Thursday, Delaware’s largest Covid-19 testing partner, Curative, Inc., will shift from using a self-administered saliva-based test to a self-administered shallow, nasal test. The new PCR testing method is expected to have the same turnaround time for results, usually within 24 to 48 hours of the test specimen being received at Curative’s lab. The new test, an Abbott shallow nasal PCR test, has been being phased in at Curative testing sites since June. Those testing sites include select State Service Centers staffed by medical personnel from the Delaware National Guard and weekly community pop-up sites staffed by Curative health care workers.
