Pembrokeshire medical technology company assisting in the fight against coronavirus – Wales247

A company based in Wales is helping in the fight against coronavirus after its clinical laboratory diagnostic equipment has been shown to have a key use for medical teams treating Covid-19 patients.

Benson Viscometers, based in Haverfordwest, Pembrokeshire, designs and manufactures clinical viscometers which are used in the NHS and in the USA to test the viscosity (or thickness) of bodily fluids, notably blood plasma, serum, whole blood and synovial fluid. The plasma viscosity test is an important diagnostic aid for a range of conditions and has now been identified by scientists as important in monitoring critically ill Covid-19 patients.

In Covid-19 patients a rise in plasma viscosity is due to an increased concentration of a clotting (coagulation) protein called fibrinogen. This raised level of fibrinogen increases the risk of a blood clot forming (thrombosis) and could explain why a large proportion of the deaths from Covid-19 are from thrombotic episodes.

A paper in The Lancet on May 25th associates very high plasma viscosity in critically ill Covid-19 patients with thrombotic complications.

An article in Newsweek on May 28th further explored this study and the links between plasma viscosity and Covid-19. The critically-ill Covid-19 patients studied had plasma viscosity levels 95 percent higher than normal, and more than 25 percent had blood clot-related complications. The researchers also found a strong correlation between plasma viscosity levels and the severity of the patients illness.

Several UK hospitals such as Addenbrookes Hospital, Cambridge, University College London Hospital and St Thomass in London, which are at the forefront of the fight against Covid-19, are conducting research into the value of measuring plasma viscosity in Covid-19 patients for diagnosis and prognosis. As higher plasma viscosity is linked to higher levels of complications, the test can aid early identification of patients who are likely to have more severe symptoms.

The plasma viscosity test is also being usedto monitor inflammatory status in the specific types of Covid-19 patients.

Deepak Singh, Head of Department, Haematosis, at Health Service Laboratories, London, said:

We are running plasma viscosity now to monitor inflammatory status in the following patient groups:

This is to ensure anti-platelet drug therapy efficacy.

Laboratories all around the world are now discussing the role plasma viscosity can play in monitoring the progression of Covid-19 to develop a more scientifically targeted treatment for patients and produce improved recovery outcomes.

The creator of the Benson clinical viscometers, Bernie Benson, said:

Amidst the huge strain and challenges caused by this global pandemic, we are grateful that we are able to make a positive contribution to improving patient outcomes. The plasma viscosity test is highly valued and routinely used by many eminent UK hospitals for a range of conditions, but it is still under-utilised in other UK settings as well as the rest of the world. We believe that the plasma viscosity test will lead to a significant breakthrough in outcomes for critically ill patients and that the world is now waking up to the huge value of this test in general.

These clinical viscometers are designed and manufactured in the UK, and the UK has a unique opportunity to fully utilise the readily available advanced technology to progress research in this field.
