As the states of California, Oregon and Washington begin strategizing on their regional plan to re-open their economies and control the future spread of COVID-19, a crucial question remains: How can businesses ensure their employees remain virus-free now and in the future?

For the thousands of western U.S. businesses seeking to safely bring their employees back to work, and tens of thousands of residents who desperately want and need to return to their jobs, a robust supply of COVID-19 tests, coupled with a systematic COVID-19 testing strategy supported by evidence-based guidelines will be key to success.


To date, the country has faced testing shortages, confusion about the various testing types, and lack of clarity around who should or can have access to tests. However, that does not mean we can't course-correct by thoughtfully laying the necessary roadmap for more transparent and effective testing guidelines as we look to reopen our economy.

The first step is a clear understanding of the current testing options available. The two predominant tests on the market are viral tests and serum antibody tests:

  • Viral, or PCR, tests determine if an individual currently has COVID-19 by testing for the virus itself through a swab of the nose or throat. These tests indicate whether the person is contagious to others, even if they are asymptomatic. Viral tests are complex and can require at least 24 hours to perform and report. The PCR test is considered the gold standard given its 90%+ accuracy rate and ability to detect even low levels of virus.
  • Antibody tests determine whether an individual has been infected with the virus and has developed an immune response (antibodies) against the virus. Antibody tests use a blood sample and can be processed relatively quickly, yet they will not identify people with an early infection, nor can they tell whether an individual is no longer shedding the virus and therefore *no longer contagious.

Both types of tests can be delivered as laboratory tests or point-of-care (POC) tests, the latter having the goal of quick turn-around and broad community delivery. However, none of the companies marketing POC tests have published accuracy data based on patient testing yet.

So where does that leave businesses looking to get their workforce back up and running? Businesses must establish protocols for appropriate testing of employees to confirm that they are virus-free before returning to work. Taking someone's temperature is NOT a valid proxy for determining whether an individual is "healthy" nor is an antibody test alone. Instead, we need to develop a clear decision tree that includes the two different types of testing.

Companies should institute a multi-step COVID-19 testing protocol:

1) Any person who previously tested positive must receive a negative viral clearance test before returning to work.

2) Any person who has no confirmation of prior infection should receive a viral test first. If they are positive for the virus, they must be retested until they receive a negative result. If they are negative for the virus, they should then have an antibody test to determine whether they were previously infected.

If negative for virus and positive on the antibody test, they can also safely return to work. If negative for the virus and negative on the antibody test, they should know they are susceptible to infection if they return to work.

For those who are still susceptible, one option is to allow them back to work, but develop a prospective viral screening protocol. These screening tests could be on a volunteer and rotating basis through the workforce, with perhaps 10%-20% being tested each week. Anyone with symptoms also should be sent home and receive immediate viral testing.

The federal government should be taking action to coordinate testing supply, help direct it to the highest priority populations and subsidize the cost of testing. Business leaders should coordinate efforts to establish testing protocols and sharing of testing resources for the workforce that reflect the most current science to ensure that workers can safely return to, and stay at, work.

Viral testing is the only established method to confirm if an individual is virus-free and therefore safe to return to work. At MiraDx, we are conducting PCR testing for COVID-19 and are seeing many individuals continue to be contagious for weeks after their last symptoms. This is significantly longer than the current CDC guidelines that indicate that individuals are "clear" to return to work 72 hours after fevers and symptoms are gone. We are completing a larger study on this issue and will report results soon.

*This story has been corrected to say that if you are no longer shedding virus, you are no longer contagious. It previously and improperly said the opposite.

This Week in LA: Robotaxis, Reels & a $100K Challenge

🔦 Spotlight

Happy Friday, LA,

It’s Coachella Weekend 2, which means fewer cars on the road, easier restaurant reservations, and just enough quiet to hear the next wave of innovation humming through the city. This week, we’re watching more driverless cars roll in, Instagram remix your Reels feed, and a $100K climate challenge call for startups. Let’s get into it.

🚕 Zoox Is Bringing Its Robotaxis to LA

Image Source: Zoox

Amazon-owned Zoox just announced that its futuristic, steering wheel–less robotaxis are heading to Los Angeles. The company has begun mapping the city as it gears up to launch a fully autonomous ride-hailing service. These aren’t retrofitted Teslas; they’re bidirectional vehicles built specifically for autonomy, with no front, no back, and no driver seat.

It’s Zoox’s first major push beyond Northern California and Las Vegas, and it's a signal that LA is being positioned as a proving ground for next-gen transportation. As the city preps for the 2028 Olympics, Zoox is hoping to help LA reimagine what mobility looks like without a human behind the wheel.

👀 More on that here:Zoox’s LA Expansion

💬 Instagram’s New “Blend” Feature

Image Source: Instagram

Instagram just announced “Blend,” a new feature that creates a private Reels feed curated for you and a friend based on your shared interests. It’s like a personalized explore page, but just for two. Think Spotify Blend, but with more memes and fewer breakup ballads.

It’s currently in testing, but if rolled out broadly, Blend could change how creators build community and how content spreads in smaller, more intimate algorithmic circles.
