## Emory Researchers Identify ALS Blood Test
Emory University researchers found a 10-protein blood signature that distinguishes ALS patients from healthy controls with 98.3% accuracy.

> We saw the proteins we expected, like neurofilament and phosphorylated tau, but we also found differences in proteins that hadn't been linked to ALS in blood before.
## Alamar Technology Used for Testing
Alamar Biosciences' NULISA technology measured over 300 neurological and inflammatory proteins in each blood sample.
## Study Published in Nature Communications
The study, published in Nature Communications, outperformed a leading individual ALS biomarker including patients with difficult-to-diagnose presentations.
## 10-Protein Signature Details
The signature combines established neurofilament markers NFL and NEFH with pTau-181 and VEGFA, plus six new proteins not previously reported as ALS blood biomarkers.
## Validation Results
In a validation cohort of 144 ALS patients and 37 controls, the 10-protein signature achieved 98.3% balanced accuracy compared with 89.9% for neurofilament light chain alone.
## Why This Matters
The signature identifies ALS patients missed by NFL alone, including those with little disability, which helps distinguish ALS from other conditions.
## Key takeaway

Emory University researchers developed a 10-protein blood test that correctly identifies ALS patients with 98.3% accuracy using Alamar Biosciences' NULISA technology.
