With the recent surge in testing demand due to the rapid spread of the Delta variant, the company has been experiencing robust demand for its portfolio of Sofia SARS and QuickVue COVID-19 rapid antigen tests. Hence, adding capacity via CVS Pharmacy is likely to aid in addressing customers’ demand.Quidel’s management has also confirmed that on the back of surging demand, it is continuing to add manufacturing units and is on-track to reach its target run-rate capacity of approximately 70 million rapid antigen COVID-19 tests per month by the end of the year.The excellent performance of the QuickVue test is likely to enable customers to run the test confidently, thereby helping to prevent asymptomatic spread of the virus.Industry ProspectsPer a report by MarketsandMarkets, the global immunoassay market is anticipated to reach $39.0 billion by 2026 from $28.4 billion in 2021, at a CAGR of 6.6%.
