INDIANAPOLIS (WISH) — A simple blood sample could help doctors identify who is at greater risk for COVID-19.
The finding comes from a study by German researchers published in the Journal of Extracellular Vesicles.
Scientists assessed blood samples from 54 patients between April 2020 and February using a COVID-19 registry. All patients had varying degrees of infection.
Researchers found that a molecule responsible for transporting viruses into the cell was higher in blood samples from people with severe cases. The molecule, phophatidylserine, is also a sign of inflammation.
“As a marker, it outperformed established laboratory markers for inflammatory processes in the body … currently used for the clinical evaluation of COVID-19,” said the study’s lead author, Dr. Thomas Brocker, in a press release.
Brocker goes on to say the findings could lead to better COVID-19 diagnoses.
