From New Atlas, a promising new diagnostic tool:
“That same research group had a secondary layer to their novel diagnostic method, combining this blood test with a second test to measure tau proteins in the cerebrospinal fluid, which is currently the only way to quantify its levels, though is expensive and invasive.”
This means a test for the disease could be done with just a blood draw, rather than a cerebrospinal fluid draw, more commonly known as a Spinal Tap. By making the test more accessible, it means more people can be tested. The more people who are tested, the more they can treat early. The test is still in the early stages of development, but it’s a promising start.
