All male employees at a care facility, where a female patient who had been in a vegetative state for years gave birth, will have to provide DNA to police.
Police served a search warrant on Tuesday to get DNA from the male employees at the long-term care facility in Phoenix.
Hacienda HealthCare said it welcomed the DNA testing of employees.
"We will continue to cooperate with Phoenix Police and all other investigative agencies to uncover the facts in this deeply disturbing, but unprecedented situation," the company said in a statement.
The woman, who had been in a vegetative state for more than 10 years after nearly drowning, gave birth to a healthy baby on 29 December.
Officials from the San Carlos Apache tribe announced on Tuesday night that the woman was a member of their community and confirmed she was still in a vegetative state when she gave birth.
"On behalf of the tribe, I am deeply shocked and horrified at the treatment of one of our members," tribal chairman Terry Rambler said.

The video, which was extensively shared on social media on Wednesday morning, shows the driver hand over a package to the customer. She then turns around to walk back inside the gates.
The driver can be seen watching the woman as he opens his fly and starts masturbating. The customer is completely oblivious to what is happening.
"Mr D Foods condemns the behaviour of the driver in the strongest possible terms and we sincerely apologise to the affected customer. As soon as the incident was brought to our attention, the driver was identified and his contract has been terminated with immediate effect," said Devin Sinclair, head of Mr D Foods .
"We have been in touch with the customer’s family and have apologised to them directly for the driver’s unacceptable behaviour. We deeply regret the incident and will provide them with any information they require to take the matter against the driver further."
Sinclair said all Mr D Food drivers were subjected to a rigorous vetting process.
