Simple Autism Test Undergoing Trials
According to a story in the Daily Mail, British scientists say that all it takes to definitively diagnose Autism is a few drops of urine, a non-evasive test. Jeremy Nicholson, from Imperial College London said that the urine of an Autistic child contains a distinctive “chemical fingerprint”.
It points to a link between Autism and the gut, a marker long suspected but never proved. Some factors point to a link between Celiac Disease (sprue) an autoimmune disease and Autism. The article published in the “Journal of Proteome Research” in June of 2010 goes on to say that the bacteria in the gut of an Autistic child is different from those found in guts of a normal child.
Researchers tested the urine of three trial groups of children, those with Autism, normal siblings of the Autistic group, and a group composed of children without Autism or Autistic siblings. With a test called H NMR Spectroscopy, they determined that each group had different chemical markings in their urine. Siblings of the Autistic child showed a different marker than the so-called normal children.
However, scientists debate whether the differences point to gut markers as a byproduct of Autism or if they cause the condition.
Similar to a test for pregnancy, this test could aid in detection of the disorder and lead to early treatment for affected babies. If trials prove successful, the test could be available as early as 2015. Early treatment promises a child a more normal life and easier integration into social structures.
Present tests for Autism consist of interviews with parents and caretakers asking many questions about the child’s history, behavior, and observation of the child by himself, with siblings and with parents.
For instance, a CHAT (Checklist for Autism in Toddlers) test asks parents a number of questions about the child’s behavior. Many other evaluations take place to arrive at a diagnosis of Autism.
Doctors are also working on a new genetic test. Dubbed the
Chromosomal Microarray Analysis (CMA), it discovers genetic abnormalities.
In March 2010, Bai-Lin Wu, PhD, medical director of the genetics diagnostic laboratory at Children’s Hospital, Boston, and a study co-researcher, relayed this information to WebMD.
Such research opens up an exciting new era of diagnosing and treating Autism in the future, and lead to a much-improved prognosis without the extensive testing in vogue today. Early treatment of the condition will lead to lives that are more productive for the children.
These physical tests for a definite diagnose open up an exciting new era of diagnosing and catching the disease at a very early age.
