A Public Health England study could help facilitate regulatory submissions for Oxford Immunotec's test to measure T cells and the immune response to SARS-CoV-2.
A number of research groups and companies are exploring use of T-cell response testing in areas like vaccine development and assessing spread of the virus.
Oxford Immunotec said that a decrease in revenues for its US business was partly driven by the impact of planned inventory destocking by Quest Diagnostics.
Of the 28 companies in the index, 21 firms saw their stock prices increase throughout the first half of the year, while seven firms' share prices decreased.
The firm said that since March, when it provided its full-year 2020 guidance, it has seen a significant decline in testing demand as a result of the COVID-19 pandemic.
