AbC-19TM rapid antibody test performance evaluation

09 July 2021

Peer-reviewed performance evaluation and self-test user experience of AbC 19TM

Omega (AIM: ODX), the medical diagnostics company focused on CD4, infectious diseases and food intolerance, notes  the press release issued today by the UK Rapid Test Consortium (“UK-RTC”), of which Omega is a partner, welcoming the publication of two peer-reviewed studies conducted by Ulster University and involving AbC-19™, a lateral flow test for the detection of neutralising IgG antibodies to the full trimeric spike protein of the SARS-CoV-2 virus.

Highlights from the studies include:

  • Excellent laboratory validation performance metrics for the AbC-19™ rapid test for SARS-CoV-2 spike protein IgG antibody detection and semi-quantitative correlation with laboratory ELISA methods assaying IgG antibodies to the spike protein of the SARS-CoV-2 virus.
  • AbC-19™ showed sensitivity of 97.58% and specificity of 99.59% when using evaluation methods as defined by the MHRA for Target Product Profile of an antibody test.
  • In addition, the study notes that IgG antibodies to the SARS-CoV-2 virus were detected 10 months after infection. Understanding the longevity of COVID-19 antibodies is important both immunologically and in helping to guide pandemic exit protocols.
  • Positive user experience score from 1,544 participants who used AbC-19™ as a ‘self-test’

Professor Chris Molloy, Independent chairman of the UK Rapid Test Consortium said: “We are entering a phase of the pandemic where testing for immunity will become as or more important than testing for infection. Rapid, accurate immunity tests are therefore a critical tool for citizens and public health providers to embrace. 

“Development of multiple antibody tests, and semi-quantitative approaches will enhance this portfolio and enable the most rapid global recovery.”
