Last year a team of researchers from Rensselaer Polytechnic Institute, US, developed a simple blood test for diagnosing ASD (autism spectrum disorder). At the present moment, a follow-up study confirms the original finding.
In this test, there is an algorithm that takes into account the presence and concentration of numerous chemicals in the blood associated with ASD.
To make the test more predictive, the scientists worked with children divided into several groups within the existing studies. Using the test, they found 154 aged from 2 5o 17 years.
Systems biologist and senior author Juergen Hahn says: “This is an approach that we would like to see move forward into clinical trials and ultimately into a commercially available test.” She also adds: “We were able to predict with 88% accuracy whether children have autism.”
A team of scientists from Johns Hopkins University School of Medicine created a new blood test that can be a much simpler and more effective diagnostic technique than most of the modern techniques. This technique called CancerSEEK and has the potential of identifying 8 types of cancer from one sample of blood.
For the study, the researchers tested CancersEEK on 1,005 individuals who were diagnosed with non-metastatic forms of one of the 8 cancers. They discovered that the test was able to identify 70% of cancers. Its sensitivity varied depending on the cancer type.
Study co-author Dr. Bert Vogelstein of Johns Hopkins University School of Medicine says: “This test represents the next step in changing the focus of cancer research from late-stage disease to early disease, which I believe will be critical to reducing cancer deaths in the long-term.”
Researchers from the US developed a method for diagnosing schizophrenia. A report about their work can be found in the journal Analytical Chemistry.
Scientists offer diagnosising chizophrenia to pay attention to oxidative stress – cell damage due to oxidation.
In their view, this mechanism is closely associated with many diseases, including schizophrenia and other mental disorders.
The new approach has been tested on a cohort of patients with schizophrenia and healthy individuals. As a result, researchers were able to correctly separate the blood samples of sick people from healthy one. For the detection of oxidative stress they used iridium salt as for the evaluation of the process in the food products.
The researchers hope that their technique will be used for the diagnosis of schizophrenia: the sooner the disease is found, the more successful it is treated. Now the diagnosis is sometimes stretched for a year.
