uBiome is back to running its only lab test, the troubled startup told customers on Thursday, a week after it was forced to stop running the test after laying off key employees.

The company had to stop processing lab samples on July 10, after cutting its lab director, Susan Zniemer. She has since been brought back on, according to an email sent to customers that uBiome shared with Business Insider.

Lab testing has resumed for the company's Explorer test, a direct-to-consumer product that tells users what microbes are in their guts. The test costs $89, and uses a small sample of an individual's poop.

"You may be aware that last week we temporarily paused processing Explorer samples while we executed an organizational change at the company," uBiome said in the email. We are pleased to inform you that Dr. Susan Zneimer will continue as uBiome's Lab Director and we have resumed processing Explorer samples. We anticipate few if any delays in delivering results to customers."

Zneimer was let go as part of a round of layoffs in which uBiome cut about half its workforce. The startup is working to find a path forward, after the FBI raided the startup in April. Following the raid, the company suspended sales of two doctor-ordered tests, SmartGut and SmartJane.

Founded in 2012, uBiome raised $105 million from investors and achieved a $600 million valuation on the promise of helping people understand the bacteria in their body, called the microbiome.
