Tutu won the Nobel Peace Prize in 1984 for his role in fighting South Africa's racist, apartheid regime. After the country's first all-race elections in 1994, Tutu chaired the Truth and Reconciliation Commission, which probed apartheid-era abuses and gave amnesty to those who confessed their crimes.
Tutu is scheduled to remain in the hospital overnight, said Odile Pearce, a spokeswoman for the Truth Commission. She declined to specify the tests Tutu was undergoing or to identify the private hospital to which Tutu had been taken.
"We should know the results by tomorrow," she said.
Tutu returned to South Africa in August after taking a two-year sabbatical to lecture on theology at Emory University in Atlanta. Upon his return he said he planned to stay out of the public eye and take a well-deserved rest.
The jovial archbishop is widely revered and loved in South Africa, where his personable manner has endeared him to people across the political spectrum.
