Real-world implementation of the INDICAID COVID-19 rapid antigen test

The INDICAID speedy take a look at was then carried out at COVID-19 outbreak screening facilities in Hong Kong as a part of a testing algorithm (termed “dual-track”) to display asymptomatic people for prioritization for confirmatory RT-PCR testing. In a single method, preliminary optimistic INDICAID speedy take a look at outcomes triggered expedited processing for laboratory-based RT-PCR, decreasing the common time to confirmatory end result from 10.85 h to 7.Zero h. In a second method, preliminary optimistic outcomes triggered subsequent testing with an onsite speedy RT-PCR, decreasing the common time to confirmatory end result to 0.84 h.

In 22,994 asymptomatic sufferers, the INDICAID speedy take a look at demonstrated a PPA of 84.2% (95% CI, 69.6% to 92.6%) and an NPA of 99.9% (95% CI, 99.9% to 100%) in comparison with laboratory-based RT-PCR utilizing mixed nasal/oropharyngeal specimens. The INDICAID speedy take a look at has glorious efficiency in comparison with laboratory-based RT-PCR testing and, when utilized in tandem with RT-PCR, reduces the time to confirmatory optimistic end result.

INDICAID COVID-19 speedy antigen take a look at

IMPORTANCE Laboratory-based RT-PCR, the present gold customary for COVID-19 testing, can require a turnaround time of 24 to 48 h from pattern assortment to end result.

The delayed time to end result limits the effectiveness of centralized RT-PCR testing to cut back transmission and stem potential outbreaks. To deal with this, we performed an intensive analysis of the INDICAID COVID-19 speedy antigen take a look at, a 20-minute speedy antigen take a look at, in each symptomatic and asymptomatic populations. The INDICAID speedy take a look at demonstrated excessive sensitivity and specificity with RT-PCR because the comparator methodology.

A dual-track testing algorithm was additionally evaluated using the INDICAID speedy take a look at to display for preliminary optimistic sufferers, whose samples have been then prioritized for RT-PCR testing. The twin-track methodology demonstrated vital enhancements in expediting the reporting of optimistic RT-PCR take a look at outcomes in comparison with customary RT-PCR testing with out prioritization, providing an improved technique for neighborhood testing and controlling SARS-CoV-2 outbreaks.
