A new blood test method to detect tiny protein clots linked to long COVID

Abstract

Imaging flow cytometry revealed a significantly increased concentration and size of amyloid microclots in Long COVID patients.

  • Long COVID is associated with hypercoagulability, leading to the formation of amyloid microclots that resist breakdown.
  • Previous methods lacked statistical robustness and rapid throughput for assessing microclot presence.
  • The current study shows that imaging flow cytometry can accurately identify variations in size and fluorescence of microclots in Long COVID patients compared to controls.
  • This technique enhances the accuracy of microclot detection beyond conventional flow cytometry, which has been widely used in clinical settings.
  • Results suggest that conventional flow cytometry could also effectively detect microclots in Long COVID and related conditions.
