Blood Test May Aid in Early Accurate Alzheimer's Diagnosis
Researchers Report Promising Results
Scientists Approach Long-Sought Goal
WEB July 28 2024 700 am Scientists have made another major stride toward a significant goal: diagnosing Alzheimer's disease with a straightforward blood test. In addition to the blood test, most patients also underwent a lumbar puncture for spinal fluid, while those who could not underwent a radionuclide scan.
The blood test screens for a type of protein called phosphorylated tau or p-tau and can be used to screen for Alzheimer's disease. The test, developed by the California-based firm ALZpath Inc., has shown promising results, with CNN reporting that it could cost between $200 and $400.
According to researchers, the blood test could help doctors diagnose Alzheimer's disease faster and more accurately. This is a significant development, as early diagnosis is crucial for effective treatment. The test's sensitivity and specificity are comparable to current methods, making it a potentially valuable tool for clinicians.
Further research is necessary to validate the blood test's performance in larger populations and to determine its long-term clinical utility. If successful, this blood test could revolutionize the diagnosis and monitoring of Alzheimer's disease, benefiting patients and their families.
