An emergency dispatcher took the call from Woods' home at 2:35 a.m. and transferred it to Orange County Fire Rescue, Orange County Sheriff's Office spokesman Jim Solomons told The Associated Press.
An adult patient was taken to Health Central Hospital in Ocoee, the same place Woods was treated after he crashed his sport utility vehicle outside his home last month, fire rescue spokeswoman Genevieve Latham said. The patient's condition was not immediately known.
Woods' agent, Mark Steinberg, did not immediately respond to an e-mail requesting comment.
Media attention has been focused on the world's No. 1 golfer since he hit a hydrant and a tree around 2:25 a.m. on the Friday after Thanksgiving. The Florida Highway Patrol last week cited Woods for careless driving and fined him $164.
The accident - and Woods' refusal to answer questions about it - fueled speculation about a possible dispute between him and his wife, Elin.
Just days before the crash, a National Enquirer story alleged Woods had been seeing a New York nightclub hostess, Rachel Uchitel, who has denied it. After the crash, Us Weekly reported that a Los Angeles cocktail waitress named Jaimee Grubbs claims she had a 31-month affair with Woods.
Last week, Woods issued a statement saying he had let his family down with unspecified "transgressions" that he regrets with "all of my heart." He did not elaborate.
A police report on the crash released Monday showed that a Florida trooper who suspected Woods was driving under the influence sought a subpoena for the golfer's blood results from the hospital he was taken to after the crash, but prosecutors rejected the petition for insufficient information.
A witness, who wasn't identified in the report, told trooper Joshua Evans that Woods had been drinking alcohol earlier. The same witness also said Woods had been prescribed two drugs, Ambien and Vicodin.
The report did not say who the witness was but added it was the same person who pulled Woods from the vehicle after the accident. Woods' wife, Elin, has told police that she used a golf club to smash the back windows of the Cadillac Escalade to help her husband out. His injuries were minor.
The sister of a neighbor who called 911 after the crash told troopers that Woods' mother, Kultida, and mother-in-law, Barbro Holmberg, were also at the scene, but the AP has not been able to confirm that.
Eva Malmborg, a spokeswoman for Holmberg, said Tuesday that she could not comment on the reports about a woman being taken from Woods' neighborhood to the hospital.
"I haven't been in contact with her and like I said I don't know where she is - and so I can neither confirm or deny anything," Malmborg said.
Malmborg confirmed Holmberg had taken a week's leave from her job as Gavleborg county governor in central-east Sweden, but said she did not know where Holmberg had gone.
There was no sign of emergency workers later Tuesday morning at the Woods' gated community, where luxury SUVs and cars drove in and out as a few reporters and television news trucks milled around outside.
