Could blood and urine tests detect autism?

Could blood and urine tests detect autism?

"We hope the tests will also reveal new causative factors", Rabbani said.

It is nearly 90 percent accurate and could be available to doctors within a year, scientists at the University of Warwick say. The outcome was a diagnostic test better than any method now available. They found children with ASD had higher levels of the oxidation marker dityrosine and certain sugar-modified compounds called "advanced glycation endproducts" in the protein.

The team took blood and urine samples from the children, aged between five and 12, and found that there were chemical differences between the two groups.

The lifelong developmental condition affects, among other things, a person's social interaction and communication, and symptoms can include restricted and repetitive behaviours and interests.

New tests that can indicate autism in children have been developed by university researchers in the United Kingdom.

In the U.S., more than 3.5 million individuals live with ASD, as indicated by Autism Society and this cutoff points 35 percent of youthful grown-ups with the turmoil from having an occupation or proceeding with their instruction after secondary school. Researchers led by a team at the University of Warwick, however, have identified the basis for what they describe as a test that flags the "fingerprints" of ASD much earlier than traditional methods. Indeed, the researchers suggest that while a combination of genetic causes, environmental factors, and rare genetic variants are known to be causes of autism, the tests could reveal other causes we now don't know about.

Because the study used a very small sample - 38 children with ASD and 31 without ASD - the team plans to repeat the study, not only to confirm its findings but also to establish whether ASD can be detected even earlier, and whether the future development of the disease can be predicted.

Naila Rabbaini, specialist of test frameworks science and co-lead on the study, said that with additionally testing of bigger number of kids at more youthful ages the group might have the capacity to discover new reasons for autism and evaluate whether treatments are working.

She said: "We have the method, we have everything".

Since there is such a wide range of ASD symptoms, it can be extremely hard to diagnose autism, especially at the early stages of development.

It produces a means of determining whether autism is likely to be present, and researchers hope to trial it next on two-year-olds. It is far too early for that.

"This study does not disclose to us how successfully this measure can separate amongst autism and other neurodevelopmental or emotional well-being conditions, for example, ADHD and tension".
