Now that disease will be detected with a single hair strand.

See the information on Mynete, the study of LinusBio, a research company located in New York state of the USA, was on the agenda.

The test involves sending a hair sample to a lab for analysis. The study showed that it accurately predicted autism 81 percent of the time. It has been described as ‘groundbreaking’ by independent scientists and is now fast tracked by the Food and Drug Administration (FDA).


Because there is no standardized test for the condition, doctors must rely on the child’s developmental history and behavior. But the New York-based startup scientists called LinusBio said their new test should not be used on its own, but in conjunction with other methods. But they insist it can help shorten the diagnostic window. “With about a centimeter of hair, we can detect the clear rhythm of autism,” Manish Arora, the company’s co-founder and CEO, told NBC News.


“The problem with autism is that it’s diagnosed, on average, at age four. By then, a lot of brain development is already happening. We want to make early intervention possible.” For the test, the scientists first use a laser to peel off the surface layer of the hair. A second, more powerful laser is then passed through the hair, measuring at 650 points per centimeter. This also turns the thread into plasma. It controls substances linked to autism, including metals such as lead, cadmium, arsenic, zinc and copper, among others.

Previous research has found higher levels of all three essential metals in the hair of autistic children. Researchers are unsure why this is the case, although it may be linked to genetic factors or exposure to environmental substances. The results are then fed into a computer program that looks for patterns that indicate autism. It was developed using studies conducted on hundreds of people in Sweden and the USA.


The scientists tested their method on strands of hair collected from 220 Japanese children when they were about a month old. The results were then compared to the clinical diagnosis of autism, which was completed when the teens were about four years old. The scientists found that their tests correctly identified autism in 394 cases (81 percent of the total). It correctly identified autism in 96.4 percent of the children, and correctly gave everything clear to 75.4 percent of the children without autism.
