Chinese COVID-19 Diagnostic Test Delivers Accurate Results in 40 Minutes Without Instrument for Less Than 70 Cents

CRISPR-COVID demonstrated a sensitivity level of near single copy and was highly specific without cross reacting to related pathogens. According to researchers, their study demonstrated that their CRISPR-based assay for COVID-19 offered shorter turn-around time and great diagnostic value, even in under-resourced settings without the need of thermal cyclers.

CRISPR-COVID takes only 40 minutes and requires no sophisticated thermo-cyclers, providing a valuable alternative to the conventional RT–PCR assay to circumvent the bottlenecks in assay turnaround time, equipment and reagent supplies for COVID-19 testing. The team noted that at research scale, the material costs of a CRISPR-COVID were less than USD 3.5, which could be dramatically reduced at production scale to less than 70 cents, making CRISPR-COVID a competitive alternative not only technologically but also financially.
