If you have any symptoms of COVID, you should try to stay at home and away from others to avoid passing on the virus. They are gentle and non-invasive, meaning patients are no longer required to practically have their brains tickled with a long, thin nasal swab. Walia expects that current strict testing requirements for travel, which vary by country, will eventually loosen, and demand for overnight and faster results will recede.

But testing will remain crucial for preventing the global spread of new variants. But if this thing is still around for a little while, testing will be the only way to prevent global spread,” she said.

Sameday Health, another testing outfit started during the pandemic, has also sought to expedite the turnaround time for COVID tests. Emad, who says the self-funded company is already profitable, thinks demand for PCR testing will hold steady as cases of the virus remain elevated. It seems Omicron doesn’t care if you’re fully vaccinated or have the booster, we are still seeing breakthrough cases in people who have their triple shot, and we are here if we are needed,” he said.

That swab goes into a tube and is sent to a lab. Some large hospitals have on-site molecular test labs, but most samples are sent to outside labs for processing. More on that later. That transit time usually runs about 24 hours, but it could be longer, depending on how far the hospital is from the processing lab. After the RNA is extracted, technicians also must carefully mix special chemicals with each sample and run those combinations in a machine for analysis, a process called polymerase chain reaction PCR , which can detect whether the sample is positive or negative for COVID.

Some labs have larger staffs and more machines, so they can process more tests at a time than others. But even for those labs, as demand grows, so does the backlog. Problems with the first CDC test kits also led to delays. Large commercial labs like those run by companies such as Quest Diagnostics and LabCorp were given the go-ahead late last month by the FDA to start testing, too.

Labs at some big-name hospital systems, such as Advent Health, the Cleveland Clinic and the University of Washington, are among those doing this. In addition, the FDA has approved more than a dozen testing kits by various manufacturers or labs under special emergency rules designed to speed the process. The kits are used in PCR machines, either in hospital labs or large commercial labs.
