iHealth has completed testing on several heat inactivated variant strains and the iHealth® COVID-19 Antigen Rapid Test was able to detect the mutations. The clinical performance has not been established in all circulating variants but is anticipated to be reflective of the prevalent variants in circulation at the time and location of the clinical evaluation. Performance at the time of testing may vary depending on the variants circulating, including newly emerging strains of SARS-CoV-2 and their prevalence, which change over time.
