Area of Science:

Molecular Biology
Virology
Public Health

Background:

Containing Coronavirus Disease 2019 (COVID-19) outbreaks necessitates frequent large-scale testing, contact tracing, and isolation.
Existing diagnostic methods may face challenges in scalability, cost, or speed for widespread surveillance.

Purpose of the Study:

To introduce LAMP-Seq, a highly scalable, modified reverse transcription loop-mediated isothermal amplification (RT-LAMP) method for COVID-19 detection.
To evaluate the performance, cost-effectiveness, and deployability of LAMP-Seq for public health surveillance.

Main Methods:

Developed LAMP-Seq, a method involving barcoding and single-step amplification of unpurified biosamples.
Pooled products were analyzed using high-throughput sequencing.
Validated the open-source protocol using 676 clinical swab samples.

Main Results:

LAMP-Seq demonstrated a limit of detection of ~2.2 molecules/µl with near-perfect specificity for SARS-CoV-2.
Clinical validation showed 100% sensitivity (up to Ct 33) and 99.7% specificity compared to RT-qPCR.
Achieved a time-to-result under 24 hours at a very low material cost.

Conclusions:

LAMP-Seq is a scalable, sensitive, and specific diagnostic tool for COVID-19 detection.
The method's low cost and minimal infrastructure requirements facilitate rapid deployment for frequent testing.
LAMP-Seq can be integrated into public health surveillance programs for effective outbreak management.
