On September 17th 2007, the BBC reported that a new DNA test may help prove if people have had their health damaged by exposure to chemicals.
Samples of DNA are taken from a healthy person and exposed to the chemicals to see which genes are affected. This is then compared to the claimants' DNA.
Experts say it could have huge implications on civil cases where workers seek compensation for illnesses caused by things such as asbestos.
The technique was developed by Dr Bruce Gillis at the University of Illinois. Dr Gillis said the technique - named msds1 - could prove an invaluable way of speeding up such cases, which can often drag on for years.
It can read the specific pattern of changes to DNA triggered by exposure to a chemical.
This unique DNA "fingerprint" can then be compared to samples taken from people making claims.
