Genetic mapping and testing have long been hailed as the future of preventative medicine, but the Royal College of Pathologists is warning Australians should be cautious about embracing it too quickly.

Genome mapping advances are on the agenda of the health informatics conference being held in Adelaide, with discussion focused on how technology can improve healthcare.

Katerina Andronis of the Health Informatics Society of Australia said efficiencies were possible.

"We need to use technology to enable the more efficient way of managing our patients," she said.

Professor William Dalton of M2Gen said people's DNA profiles should be held in a national database in conjunction with facts about their medical history and lifestyle.

"It's not just knowing the genome, it's putting it in the context of the system," he said.

"We can predict how a patient may develop a disease or respond to therapy."

National framework needed

Professor Graeme Suthers Royal College of Pathologists agreed a DNA test might soon hold the key to revolutionising patient care.

"The ability to sequence the entire human genome, an individual's entire genetic code, is now literally within our grasp," he said.
