I have read in todays press that it is possible to do a Blood Test to diagnose Autism. You can google the info. I am surprised that it is possible to do a blood test to diagnose Autism as it is really a personality with traits. I do not if it applies to Adults. I am sure that if there is a real blood test many of us would be found not to have Autism but it would not help as we have the traits. I do not know if one just has Asperger Syndrome whether that would show up on a blood test.
If you have any information or views on this subject I hope you will reply to me.
My son had a blood test when he was going through the diagnosis they told me it was to see if it was genetic
This text has been taken from the NHS website (https://www.nhs.uk/news/pregnancy-and-child/new-blood-test-autism-long-way/):
"The study involved 38 children with ASD and 31 children without. Blood and urine samples were collected from all children and tested for various protein by-products, some of which are thought to be found at higher levels in people with ASD.
"Based on the results of the tests, the researchers developed a computer-based model to predict whether a child had ASD or not. The model correctly identified 92% of the children who had ASD, and 84% of the children who did not.
"This was an early study which provides the basis for further research. However it is far too soon to know if the test could ever be used in practice. [My emphasis.] From this single, small study we don't know that it's accurate enough or that it could improve upon existing methods for diagnosing ASD in clinical practice.
"The causes of ASD remain largely unknown, and any ways of improving our understanding of the condition are welcome. But media claims that this new test would help spot ASD early currently have no basis. [My emphasis.]"
You will note there is no reference to adults.
And a sample size of 69 participants is just way too small to draw any reliable conclusions.
Thanks for all the replies. Yes I am sure it is not conclusive yet especially the one with National Health text. I wonder if it is possible to ask the Doctors if it will be available for Adults as well as children eventually.
David said:I wonder if it is possible to ask the Doctors if it will be available for Adults as well as children eventually.
I do not believe that such a question is relevant at this stage. Further research may, for instance, prove the test is inaccurate.
The study also seems to focus on early detection of autism. In the conclusions of the findings, it is stated:"For future studies, we suggest firstly validation of the current findings in an independent clinical study group. Thereafter, priorities are investigation of the biomarkers in children younger than 5 years old to assess their ability to improve diagnosis at earlier stages of ASD development..."
The findings are published in the journal Molecular Autism:https://molecularautism.biomedcentral.com/articles/10.1186/s13229-017-0183-3
I would think the blood test could only be to measure hormone (testosterone) levels as that's the only (autism related) marker I've ever read of that would be measurable in the blood (based on the whole 'male brain theory'). If indeed it is testosterone / hormone levels in general that are being measured then the test could only be used in young children long before puberty kicks in.
Could the test be given to Pregnant women? If it could then there is a danger that they might decide to abort their babies if they know it has Autism. I hope that test will be restricted to children when they are already born.
Thanks for the replies.
.....Greetings to all here. I Post great support to what "Caretwo" first says. Please listen to that.
...If the stated "Test" were TRUE, then they would gain the same results in Autistic Adults. But, indeed, where is the research specifying and/or correlating *that*?
I don't know if the test could be given to pregnant women.
According to the 'male brain' theory, autism is / could be caused by the child receiving too much testosterone whilst in the womb. This happens at a very specific time and, in theory at least, could be tested for. In practice, I think there would be too many variables. If this test ever does reach the stage of being repeated on a larger scale, it would likely only apply to children after birth. (And not immediately after either.)
I think there's a lot more going on in resulting autism than simply a perfectly timed and measured overdose of testosterone. There are genes involved (a specific combination of several possibilities which, on their own, don't mean autism but which when combined do) which one or more parents must carry. Even a genetic test wouldn't be certain because having a gene doesn't mean it's expressed. Also, everyone's autism would show a different genetic make-up (Like everyone's fingerprint) hence the wide spectrum and no two autistic people being exactly the same.
I think we're a long, long way from an autism test. Especially in pregnancy.
Thanks for the heads up, and pointing to a reliable source (NHS). Personally, I'd be surprised if these results were reproduced by other researchers, partly because it seems so unlikely that autism has a single cause. A lot of people have been looking for contributory genes, but those identified only seem to account for at most 25% of cases of autism, whereas this feeds more into the 'oxidative stress' and 'auto-immune' ideas.
The selective increase in DT may suggest a role of increased DUOX activity in subjects with ASD. DUOX expression is increased through activating transcription factor 2 in inflammatory signalling. DUOX has an important role in gut mucosal immunity, host–microbe homeostasis, and signalling for neutrophil recruitment into allergic airways. Gut microbiota may be influential in the development of the behavioural phenotype in ASD children
I'd guess they're looking for a maintenance drug as much as a test, although that would meet a lot of resistance. Here's the press release, less balanced than the NHS: https://warwick.ac.uk/newsandevents/pressreleases/blood_and_urine/
