Framingham Company Seeks Coronavirus-Positive Volunteers To Develop COVID-19 Antibody Test

FRAMINGHAM – Kephera Diagnostics has launched a new study aimed at collecting blood samples from volunteers at least 18 years of age who have been confirmed positive for COVID-19, for use in the development of an antibody test for the virus.  

The new test will determine whether symptomatic as well as asymptomatic individuals have been infected with the virus that causes COVID-19 by detecting antibodies to specific fragments of the virus, said Kephera Diagnostics.

Volunteers will be provided with a kit to collect a finger prick blood sample at home, which will be returned in a prepaid mailer to the company for use in test development, explained the company.

The Framingham-based company is located at 1 Grant Street.

“The test under development is an ELISA and will rely on selected fragments of coronavirus proteins that are recognized and bound by IgG and IgM antibodies in patient serum,” said the company in a press release.

Kephera scientists have identified sensitive and specific antibody targets within the virus causing COVID-19 using a combination of bioinformatics, laboratory experimentation, and experience in development of similar tests for the original SARS virus that caused an outbreak in 2003-4, said the Framingham-based company.

The test is intended to provide quantitative as well as qualitative results, indicating whether an individual was infected with COVID-19 and if so, the levels of their IgG and IgM antibodies, said the company.

Individuals who are asymptomatic or who had symptoms but may not have been diagnosed with COVID-19 are likely to have made antibodies which persist for some time after their infection resolves, and these antibodies can be detected using a sufficiently sensitive and specific antibody test, said Kephera.

However, the levels of antibody in COVID-19 patients appear to be low in many cases, making them more challenging to detect, which is why a highly sensitive test is needed, said Kephera in a press release.

An important, emerging question is whether individuals who have antibodies to the virus that causes COVID-19 have acquired protective immunity, said the Framingham company.

To answer this question, tests which can accurately measure the levels of IgG and IgM antibodies quantitatively in blood samples are needed., said the Grant Street company.

“The test that we are developing will enable such quantitation and may eventually be useful in determining whether an individual has a high enough level of antibodies to be considered immune to re-infection,” said Kephera. 

While the current study is aimed at supporting test development, Kephera expects to make the COVID-19 antibody tests available for diagnostic use through its laboratory once they are approved, said the company in a press release.
