Biomarkers could be used in a quick, inexpensive COVID-19 blood screening tool

(Lawson Health Research Institute) A new study suggests that COVID-19 affects the human body's blood concentration levels of specific metabolites - small molecules broken down in the human body through the process of metabolism. Three specific metabolites identified in this study could act as biomarkers and one day be measured through an inexpensive blood test to quickly screen patients for the disease and predict which patients will become most critically ill.
