Scientists Move Closer to Potential Blood Test for Detecting Long COVID

With a lack of specifically identifying biomarkers, doctors have found it difficult to identify whether patients are suffering from long COVID.

Since the outbreak of the pandemic, medical researchers have been unable to define a common set of symptoms for the complex long COVID condition.

A recent study led by the Icahn School of Medicine at Mount Sinai in New York and Yale School of Medicine discovered that people suffering from long COVID have distinct hormonal and immune differences, and that long COVID is a biological disease with specific biomarkers that can be used to differentiate the condition.
