Additional Chief Judicial Magistrate-I Ajmer Khagendra Sharma granted permission to the ATS to carry out the test after it had moved an application in this regard on Saturday, a senior ATS official told reporters.
An ATS team will take Gupta to Hyderabad to get the tests conducted.
Gupta, who is believed to have links with Hindu group Abhinav Bharat Sangathan, was arrested last week from here when he had come to meet his ailing mother. He is suspected to be involved in the blast inside the Dargah of Khawaja Moinuddin Chishti.
Officials are also probing Gupta's alleged links with Sadhvi Pragya Singh Thakur, a key accused in the Malegaon blast case.
The ATS also arrested another suspect Chandrashekar from Madhya Pradesh in connection with the case. Both are being interrogated under police custody and will be produced before the court on May 12.
Three persons were killed and 15 others injured in the blast in the Ajmer Dargah in 2007.
Ajmer: A court here Monday granted permission to Rajasthan ATS to conduct narco-analysis test on Ajmer Dargah blast case suspect Devendra Gupta.
