Nelson Mandela has left hospital after successful medical tests and returned to his home in Johannesburg on Sunday, according to the African National Congress.
The former president and anti-apartheid leader was admitted to a hospital in Pretoria, the capital, on Saturday.
"The doctors have completed the tests," said a statement by Mac Maharaj, the official spokesman of the South African president, Jacob Zuma. "He is well and as before, his health remains under the management of the medical team."
Maharaj appealed to the public and media to respect the privacy of Mandela, 94, and his family.
The ANC, South Africa's ruling party, had earlier released a statement saying it believed Mandela was in "capable and competent hands".
Mandela, who has become increasingly frail in recent years, was in hospital for nearly three weeks in December, when he was treated for a lung infection and had surgery to remove gallstones.
Under South Africa's white-minority apartheid regime, Mandela spent 27 years in prison before he was released in 1990. He became the nation's first democratically elected president in 1994 under the banner of the ANC. He served one five-year term before retiring.
