Test predicts which COVID-19 patients will grow worse, Stanford Medicine study find

Stanford Medicine – Elevated virus levels in hospitalized COVID-19 patients’ blood predicts worsening respiratory symptoms and suggests ongoing viral replication in later disease stages, Stanford Medicine-led study says. A one-time test could predict which people hospitalized with COVID-19 are likely to worsen significantly during their stay, even if they were admitted with relatively mild symptoms, according to a study of more than 2,500 people headed by researchers at Stanford Medicine.
