Boost for Scottish diagnostics company as study suggests its test combines well with vaccine



A clinical study has suggested that a Covid-19 antibody test produced by a consortium including Scottish company Omega Diagnostics should be used with the Pfizer-BioNTech vaccine.

The research conducted at the University of Birmingham highlighted the effectiveness of the AbC-19 TM rapid antibody test in demonstrating immune response following vaccination.

During the study, the test – produced by a consortium led by Abingdon Health – was used to test individuals who had been given a single dose of the Pfizer-BioNTech vaccine.

A statement from the UK Rapid Test Consortium (UK-RTC) consortium read: “The initial data from the study being performed at the University of Birmingham supports the rationale that vaccination programmes could benefit from determining an individual’s antibody status not only after vaccination but also prior to vaccination.

“Should these results continue to be seen in further studies, and with other vaccines, this demonstrates that the AbC-19 TM antibody test could potentially assist in patient stratification and resource management in overburdened international healthcare settings.”

The preliminary study is another boost for Omega, based in Alva in Calckmananshire, which has seen its share price rise since its work on the UK-RTC started to bear fruit.

A recent study by scientists at the universities of Bristol, Warwick and Cambridge showed that the AbC-19 rapid test had the highest accuracy – at 97.3% – of four lateral flow rapid antibody tests using the same cohort of sample.

It showed that the AbC-19 is highly accurate when tested on samples from individuals previously positive for the virus by PCR tests and from samples collected pre-pandemic. The research is now being peer reviewed.

The AbC-19 rapid test confirms the presence of virus neutralising antibodies to the spike protein of it in a small blood sample.

The neutralising antibodies may be produced as part of the body’s immune response following Covid-19 infection or post-vaccination. They not only bind to a virus, but in a manner that blocks infection.
