The company was founded in 1995 by brothers
Shivinder Mohan Singh and
Malvinder Mohan Singh as Specialty Ranbaxy Limited (SRL), a 50:50 joint venture between
Ranbaxy Laboratories and US-based Specialty Laboratories. It became the first pathology company in India to receive accreditation from
National Accreditation Board. In 2001, SRL became a wholly owned subsidiary of Ranbaxy Laboratories after Ranbaxy bought out Specialty Laboratories' stake; the company was subsequently renamed SRL Ranbaxy. In 2008, SRL Ranbaxy was renamed as Super Religare Laboratories. In 2010, Super Religare Laboratories acquired Piramal Diagnostic Services and its network of 107 laboratories from
Piramal Healthcare for 600 crore. In 2011,
Fortis Healthcare completed the acquisition of 74.59% stake in Super Religare Laboratories. After being acquired by Fortis, the company rebranded itself as SRL Diagnostics. In 2021, SRL Diagnostics acquired the remaining stake in its
Kerala-based joint venture, DDRC, for 350 crore. With the addition of DDRC's 220 labs to its lab network, SRL became the biggest pathology lab chain in India with a total of 430 labs. In 2023, SRL Diagnostics changed its name to Agilus Diagnostics. ==Operations==
