New Delhi, Aug 14: Union Home Minister Rajnath Singh today underwent tests at the All India Institute of Medical Sciences (AIIMS) where he was admitted with complaints of abdominal pain. Doctors performed colonoscopy on him along with few other tests. Colonoscopy is an endoscopic examination of the large intestine and the distal part of the small bowel.

“He underwent colonoscopy test this morning. His condition is perfectly stable. He will be discharged by the afternoon,” said a senior doctor at AIIMS. 63-year-old Singh was admitted last night with complaints of pain in his lower abdomen, sources close to him had said.
