Will it ever be possible to diagnose autism with a urine test? A few British researchers are of the view that it may be possible, after they could discover what they term as a unique chemical fingerprint in the urine of kids who have the condition.

Autism at times is difficult to diagnose as it can be confused with other behavior-related troubles. Kids usually are examined via social interaction and communication tests. However, a majority of children are not diagnosed until their preschool years and at times even in much later periods.

Since the parents of kids suffering from autism often report that their kids suffer from distinct gastrointestinal troubles, one theory is that autistic kids have a unique bacterial structure in their intestines.

Now researchers say that it is very much probable to differentiate between autistic and non-autistic kids by simply taking a look at the byproducts of their intestinal bacteria and the body's metabolic procedures in the children's urine.

Using spectroscopy, lead researcher Jeremy Nicholson, a Professor at Imperial College London, and contemporaries from the University of South Australia tested the urine in almost 100 kids, aged three to nine, who were divided into three groups: those diagnosed with autism, non-autistic siblings of kids suffering from autism, and a control group with no history of autism in the family.
