How Close Are We to Patient-Side Troponin Testing?

Area of Science:

• Cardiology
• Biomedical Engineering
• Clinical Diagnostics

Background:

• High-sensitivity cardiac troponin (hs-cTn) testing is crucial for diagnosing acute coronary syndrome (ACS).
• Traditional laboratory testing has limitations in rapid emergency assessment.
• Emergence of point-of-care (POC) troponin assays with comparable analytical sensitivity.

Purpose of the Study:

• To review the latest POC troponin assays.
• To explore the clinical utility of POC troponin testing in various settings.
• To identify evidence gaps for widespread adoption.

Main Methods:

• Literature review of recent POC troponin assays.
• Analysis of current clinical data on POC troponin use.
• Discussion of implementation challenges and future directions.

Main Results:

• New POC troponin assays demonstrate requisite analytical sensitivity.
• Potential applications span emergency departments, community, and pre-hospital settings.
• Significant evidence gaps remain, particularly regarding whole-blood trials.

Conclusions:

• POC troponin testing has the potential to expedite ACS assessment.
• Clinical trials using whole blood are essential for safe implementation.
• Integration with biosensors and AI can further enhance cardiovascular care.
