A blood test at the time of admission to the hospital showing the presence or absence of SARS-CoV-2 would possibly identify patients at higher risk of severe COVID-19.
Patients admitted without viruses in the blood have an intelligent possibility of immediate recovery, according to researchers from the Karolinska Institute and Danderyd Hospital in a new publication in the clinical journal Clinical Infectious Diseases.
Blood samples were taken from patients with confirmed COVID-19 infection within 3 days of admission to the Department of Infectious Diseases at Danderyd Hospital in Sweden. Patients with measurable grades of the new SARS-CoV-2 coronavirus in the blood were seven times more likely to expand critical symptoms and 8 times more likely to die within 28 days.
This easy-to-perform verification allows us to identify teams of patients at high or low risk of severe COVID-19, allowing us to better advise the treatment and follow-up of those patients. “

Researchers analyzed the presence of viral RNA in the blood, a popular hospital strategy called PCR in samples taken from a total of 167 patients. Sixty-one patients had measurable degrees of the virus in their blood and 15/61 (25%) died inside. 28 days of the blood sample.
This can be compared to 3 deaths (3 percent) among the 106 patients who did not have measurable degrees of viruses in their blood. The presence of viruses in the blood is older with age and much more common in patients over 60 years of age. .
