In a brand new research, printed in PLOS ONE, scientists from Queen Mary College of London present that their lab-in-a-backpack method is as efficient as commercially obtainable Covid-19 exams at detecting SARS-CoV-2.
The compact package is comparatively cheap to make, costing $51 in whole. It might provide an alternate testing resolution for resource-poor international locations or distant areas with little entry to well-equipped testing labs or educated personnel to course of samples.
The testing package relies on a easy, non-invasive Covid-19 LAMP take a look at and makes use of low-cost {hardware}, together with a centrifuge made out of recycled pc onerous drives to course of samples.
The LAMP take a look at is a extensively accepted different to the generally used PCR take a look at, has the same sensitivity however not like the PCR take a look at doesn’t require temperature biking, solely a single excessive temperature to amplify any potential virus RNA. This enables the take a look at to be carried out with solely minimal tools and reagents. As a result of the LAMP take a look at makes use of saliva samples, it additionally avoids the necessity for invasive, uncomfortable nasal swabs. Nonetheless, the excessive prices of commercially obtainable LAMP exams, in addition to the costly lab tools required to run them, signifies that present industrial approaches aren’t appropriate for distant areas, or in-home testing.
Based on the researchers, subsequent steps will embody making the package directions much more comprehensible so that individuals can use them no matter their expertise or language, in addition to validating the package with actual affected person samples. Professor Stoyan Smoukov, Professor of Chemical Engineering at Queen Mary College of London, mentioned:
“We’re excited for the potential of this cell lab to do Covid-19 exams and the chance to democratize entry to cheap testing know-how. It’s made attainable by our philosophy of making low-cost devices each time attainable from advances in electronics, or current devices.
“Reuse is a excessive worth possibility for vitality and supplies sustainability, and we’re glad that slightly than exporting electronics waste to growing international locations, we will export methods to empower individuals and switch waste pc onerous drives right into a centrifuge. The Covid-19 take a look at is a well timed software, however we additionally imagine with this CentriDrive package individuals might carry out a big array of routine blood and urine exams, offering a centrifuge away from central hospital amenities.”
