Viscosity testing8/25/2023 Prior to the emergence of COVID-19, plasma viscosity (PV) testing has been commonplace for many years, albeit in larger specialist referral laboratories. At present, there is no blood test for virus severity. Reports reveal that 20% of positive cases are asymptomatic, 14% are severe and needing medical attention, and 5% require critical care. Symptoms range from cough, pyrexia and loss of taste/smell, to severe respiratory disorders, cytokine storm, microclot formation and multi-organ failure. ![]() 1 Originally designated 2019 novel coronavirus (2019-nCOV), the World Health Organization (WHO) formally named the disease COVID-19 with the causative virus responsible being termed severe acute respiratory syndrome coronavirus (SARS-CoV-2). The emergence of a novel pneumonia-inducing condition was reported in Wuhan, China, in late 2019, resulting in an unprecedented global pandemic, infecting at least 140 million people and responsible for more than 3 million deaths worldwide. ![]() Plasma viscosity levels are significantly increased in patients testing positive for SARS-CoV-2, and an inexpensive, accurate test aids in identifying positive cases and monitoring disease progression.
