Discussion

Novel assay quantifies protease activity with 88% sensitivity in plasma samples, indicating potential for timely sepsis detection.

MAIN FINDING: A multiplexed assay for sepsis diagnosis achieves 88% sensitivity and 87% specificity.
KEY EVIDENCE: The assay utilizes modified protease substrates to generate distinct mass-to-charge signatures.
APPROACH: Developed an analytical method using mass spectrometry to measure protease activity in plasma samples.
SIGNIFICANCE: This rapid and low-cost platform enhances diagnostic capabilities in clinical sepsis detection.

Caton et al. (2025) studied this question.
