Researchers have developed a test that works by detecting chemical clues shed by brain tumors into the blood. They say it could help improve brain tumor survival by making diagnosis quicker and more efficient.
The test relies on infrared spectroscopy to examine the chemical makeup of a person’s blood, combined with an AI program that can spot the chemical clues that indicates the likelihood of a brain tumor. The researchers used the new test on blood samples taken from 400 patients with possible signs of brain tumor. Using the test, the researchers were able to correctly identify 82 percent of brain tumors. The test was also able to correctly identify 84 percent of people who did not have brain tumors, meaning it had a low rate of false positives.
