A group of researchers from the Rensselaer Polytechnic Institute (USA) published a paper describing a reliable set of biomarkers in human blood that can indicate signs of an autism spectrum disorder. Clinical studies have confirmed that this complex disease can be diagnosed today in 97.6% of cases by blood analysis. Or with a probability of 96% to prove his absence if there is no disease.
The main problem in the diagnosis of autism is the mandatory study of the behavioral characteristics of the patient, which puts enormous difficulties when working with infants. Scientists around the world are looking for alternative signs, even if they are not the most accurate – but they can be studied under a microscope, rather than in a psychiatrist's office. In a new study, such a criterion is described – a complex of 24 metabolites that can be analyzed algorithmically to conclude that autism exists.
The problem is that the methodology is based not on scientific information, but on statistical information. Researchers have no idea how these 24 metabolites are associated with the development of autism, they just state that they are present in both explicit and implicit patients. Although in practice it all depends on the accuracy of the data collection – when compared with another large-scale clinical trial, it turned out that there were only 22 metabolic markers. In addition, the analyzes were taken in patients aged 3-10 years, but what happens in the body of very small autistics?
At this stage, there is no talk of creating a new method for diagnosing autism, scientists have only taken an important step in this direction, but they do not know how long it will take to work. While we can only state an important fact – autism can be detected through a blood test.js.src = “&version=v2.8”; 'script', 'facebook-jssdk'));
