An invalid result means the test was not able to tell if you have COVID-19 or not. If the test is invalid, a new swab should be used to collect a new nasal specimen and the test should be run again, using a new test cassette and extraction buffer tube. If the problem persists, call (800) 838-9502 for assistance. Customer Service hours are 5a.m. – 5 p.m. (PST), 7 days a week.
