With Thanksgiving just days away, Sophie Krakowski wanted a COVID-19 test, and the results, right away. So she came to a storefront on Elizabeth Street.

"We’re doing a small Thanksgiving, just my family, my aunt. But we’re all getting tested because my parents are over 65. So just to be smart, me and my three sisters are all getting tested ahead of Thanksgiving," she said.

Rapid Test NYC is a new kind of business, a for-profit coronavirus testing site, born out of necessity in the pandemic.

Unlike urgent care sites, clinics and hospitals, everyone must pay out of pocket. It does not take insurance, although clients can file a claim with their insurers.

Krakowski had once waited four hours for a test at an urgent care clinic. She visited Rapid Test NYC after seeing an Instagram post about it.

"The speed is the quickest," she said. "It’s a gorgeous testing center. It feels very clean inside. I just had a good experience here."

Mark Golberg launched the testing center in October with his father, Dr. Alexander Golberg. It's an outgrowth of their at-home testing concierge service.

"The demand right now, I think, is particularly high due to the holidays," Mark Golberg said.

They charge $250 for a rapid test, with the results returned in as soon as 25 minutes.

A more accurate test, known as a PCR, is sent to a lab for same-day results. It costs $450.

"This is something that's needed," Mark Golberg said. "There's obviously free testing everyone has access too."

But, he added, "Since we charge money for the test, this is a different kind of demand."

"It's very difficult to provide services and especially now, in this second wave looks like it's coming now, we need to get as many people tested as possible," Alexander Golberg said.

On the Upper West Side, Dr. Stuart Weiss opened a rapid testing service created for TV and movie productions for anyone who needs results quickly.

"The normal test results are coming back a day, two days, three days later," Weiss said. "But some people that are traveling or visiting family members or their job requires it, we give them results within an hour."

Weiss plans to stay open even after a vaccine becomes available.

"We're hoping to pivot to a center that can give vaccine," Weiss said. "We'll play whatever role we need to play to help us, as a community, get through the pandemic."
