Blood tests can warn of severe covid-19
In a unique study, Swedish researchers have studied the immune response in covid patients during the course of the disease. Preliminary results show that there may be some form of markers in the blood that reveal the severity of a patient’s illness early on.
– We understood that this would be great, says immunologist Anna Smed Sörensen about the study that shows that blood can reveal from the beginning how sick a patient with covid-19 will be.
When the first COVID-19 patients began to appear after sports holidays, immunologist Anna Smed Sörensen and her research group at the Karolinska Institutet were prepared. For several years, they have been conducting a study in collaboration with the Karolinska University Hospital, where they took blood samples and samples from the respiratory tract of patients with influenza who came to medical attention. Now the research team could easily switch and instead start collecting samples from patients infected with the new coronavirus in a systematic way.
