We understand that there could be a correlation between a plasma viscosity test result and the level of virus severity in hospitalised Covid-19 patients. It is universally agreed that a person demonstrating symptoms of inflammation will have an increased plasma viscosity.
There is also increasing anecdotal evidence to suggest that it would be beneficial to establish whether a plasma viscosity result could be used to indicate which patients may require a more aggressive therapeutic intervention. The plasma viscosity test is already established in NHS hospitals including some at the forefront of our fight against Covid-19 such as UCLH and St Thomas’s in London.
Plasma viscosity is an inexpensive test that provides rapid and straight forward numerical results with a high level of confidence within minutes of getting a blood sample to the hospital laboratory, especially given most hospitalised Covid-19 patients are already having daily blood samples taken for their haematology profile.
When a daily monitoring routine is started as early as possible, a valuable record of the Covid-19’s progress will be available to aid clinicians and researchers.
A separate and interesting topic has arisen which is the identification of those recovered patients who would be suitable as antibody donors. Those with high titre (concentration of) antibodies would have a raised plasma viscosity result.
