Quest Diagnostics Incorporated , the leading provider of diagnostic testing, information and services, today announced that its wholly-owned subsidiary Quest Diagnostics India Pvt. Ltd. has entered into a long-term agreement to provide health assessment services, including diagnostic laboratory testing, for Birla Sun Life Insurance Company Limited (Birla Sun Life), a joint venture between The Aditya Birla Group, one of the largest business houses in India, and Sun Life Financial Inc., a leading international financial services organization.

Under terms of the agreement, Quest Diagnostics will generally have the exclusive right to provide full-service medical screening and diagnostic testing of life insurance candidates, and related administrative services for Birla Sun Life's individual life-insurance underwriting business. Birla Sun Life is a leading insurance carrier in India's burgeoning life-insurance premium market, which is predicted to more than double to $100 billion by 2012.

"Birla Sun Life Insurance has, once again, opened a new chapter in the history of Life Insurance in India, whereby we envision setting new levels of service, new standards in underwriting and improving quality of underwriting and risks involved," said Vikram Mehmi, President & CEO, Birla Sun Life Insurance. "Quality and standardization of medical reports and effective handling of underwriting and operations are the benefits to be reaped by this initiative. Birla Sun Life Insurance is happy to associate with Quest Diagnostics, which works with Sun Life Financial in some countries, and is an established name world-wide in providing diagnostic services."

Demand for insurance products in India has grown significantly in recent years, driven by deregulation of the insurance industry in 2000 and a growing middle class with the disposable income to buy insurance policies. It has been predicted that the premium market for India's blossoming life insurance sector, now at $40 billion, will more than double to as much as $100 billion by 2012.

"Quest Diagnostics, through its ExamOne risk-assessment business in the U.S., has more than 30 years of experience providing medical screening, diagnostic testing and other risk assessment services to leading insurance companies in North America," said Janak Singh Bajwa, managing director, Quest Diagnostics India Pvt. Ltd. "Through our agreement with Birla Sun Life, we bring to India a level of expertise in health assessment, testing, and related services that has, until now, been largely absent from the country's booming life insurance market. As India's insurance market continues its fast paced growth, we look forward to delivering services that will enable Birla Sun Life to drive quality and cost efficiencies in its underwriting process."

Customer experience during the medical examination is an important touch- point for life insurance sales. To ensure standardization and a quality experience, Birla Sun Life Insurance has been evaluating processes which would result in consistent and positive experience across the country. The Quest Diagnostics partnership has been forged with this objective.

Quest Diagnostics will provide a range of health management services to Birla Sun Life, including laboratory testing through its new 65,000 square- foot diagnostic testing facility in Gurgaon, as well as case management and appointment scheduling of medical exams by trained and credentialed physicians. Quest Diagnostics will serve Birla Sun Life using the company's proprietary ExamView medical services and CaseView laboratory-test ordering and reporting software, which is used by the company's risk assessment business, ExamOne, based in Lenexa, Kansas, to serve insurance companies in up to 20 countries around the world.

"This arrangement is significant and important in the journey of Birla Sun Life Insurance," added Mr. Mehmi. "We are embarking on the phase of the pilot in two cities. Transition from other centers will happen in a phased manner. We will use our learning's to enhance our processes so that we have happy customers. It is also a proud moment for us as we have insured over 2 million lives."
