Researchers at Edinburgh University claimed that they have come up with a procedure of detecting variations in a person's genetic code that is convenient and inexpensive. This can be done by using a chemical test on saliva resulting in quick and cheap DNA tests for risks of certain diseases, according to the research.

It was also assured by the researchers that their "chemical analysis based" procedure would provide more trustworthy results as compared to the present DNA testing which involve expensive enzymes.

Juan Diaz-Mochon of the University's School of Chemistry, who led the research said, "The chemical method was able to detect genes linked to cystic fibrosis in laboratory experiments using synthetic DNA. We're hoping to bring the first test for cystic fibrosis to the market within five months. With the scientific data we already have, we believe we can develop this test further and in different ways".

Juan and his team were aided by the funds from commercial partners and the Scottish Enterprise fund. They consequently plan to market a cystic fibrosis test and find for any possibility of same method decoding entire human genomes. This study was published in the journal Angewandte Chemie.

Diaz-Mochon further added, "This chemical method would offer a speedy, cost-efficient alternative to existing DNA analysis. Our method could help reach the goal of complete genome analysis in a few hours for less than $1,000".
