New Blood Test Aids Early Alzheimer’s Detection in India
A new blood test called pTAU/Aβ1-42, approved by the US FDA and Central Drugs Standard Control Organisation, can help doctors find Alzheimer’s disease early.
This test is combined with special brain scans called PET and MRI.
In India, these scans are very expensive and not everyone can get them.
The new blood test is easier and cheaper.
Doctors can now find Alzheimer’s before people get very sick.
This helps families plan and get treatment earlier.
The test was talked about at a meeting in Gurugram.
Many older people in India have Alzheimer’s, and this number is growing.
The new test can help a lot of people.
New pTAU/Aβ1-42 blood biomarker test approved by US FDA and Central Drugs Standard Control Organisation.
Test integrated with PET and MRI imaging for early Alzheimer’s detection.
High cost and limited availability of amyloid PET scans in India have restricted access.
Blood-based biomarkers allow earlier diagnosis and intervention.
Symposium in Gurugram discussed the new diagnostic approach and its implications.
