"HHS knows the identity and location of every minor in the care of our grantees", he said, adding that authorities were working to reunite children with their parents "as expeditiously as possible".
Judge Dana Sabraw had issued an injunction on June 26 requiring the government to reunite detained migrant children under the age of five within 14 days and those over that age within 30 days.
Immigration activists say the that DNA data can be easily abused once it is collected by the USA government, and may be used to track a migrant's whereabouts.
Earlier this week, the US Department of Health and Human Services (HHS) said it had ordered DNA tests on some 3,000 children in an effort to reunite migrant families.
Azar told reporters on Thursday that officials have identified "under 3,000" children potentially separated from parents.
Azar said HHS is now tasked with reuniting almost 3,000 children with their parents because the court deadline includes children separated before the zero-tolerance policy went into effect.
Anthony Bourdain leaves majority of $1.2M estate to daughter
The court will appoint a guardian ad litem to represent their daughter Ariane's interests, because she's a minor. The documents also state that Bourdain has a mortgage worth $1.1 million, though the property is not specified.
The Department of Health and Human Services, which is responsible for both children taken from their parents and those who came to the US with an adult, is now trying to match families. The Trump administration in a court filing late Thursday night requested further guidance from the court on reuniting the families, saying the government may need more time in certain cases.
Azar said that verification process in some cases involves DNA testing.
Jonathan White, a Health and Human Services official, filed a declaration with the court that gives perhaps the most detailed account yet of what the government is doing and the hurdles it faces.
On Thursday, Azar said the Trump administration "will comply" with the deadlines - though he assailed the judge's timetable as "extreme".
Hurricane Beryl Moving Westward Over Tropical Atlantic
It will most likely return to its tropical storm status by late Sunday or Monday as it approaches the Lesser Antilles. The Met Office assured the public that Trinidad and Tobago is not under any Tropical Storm watch or warning.
He added that he believed the complexity of the reunifications was caused by the federal judge's "extreme" deadlines and the U.S. immigration system itself - not the Trump administration.
The U.S. Department of Justice asked the U.S. District Court in San Diego to clarify if it would be breaching the court's order if families were reunited after the deadline due to delays in confirming parentage.
The DOJ also expressed concern about the reunification timeline as it determines whether a parent has a criminal history.
Prosecutions have been pursued against illegal immigrants in previous administrations, but they were rarely used on families - a fact that became known among smugglers and migrants, who then began to bring their children in order to take advantage of the family "loophole".
Lee Gelernt, deputy director of the ACLU's Immigrants' Rights Project, had this reaction to the action in court on Friday, according to a news release: "The judge made it very clear he wasn't going to allow the Trump administration to drag its feet on reunifying these children with their parents".
