Quantitative PCR (qPCR) after reverse transcription (RT), the standard method, is very sensitive but requires expensive instrumentation. Loop-mediated isothermal amplification (LAMP) is an alternative to qPCR that is faster and requires fewer resources. Dao Thi et al. tested the RT-LAMP assay on several hundred clinical RNA samples isolated from pharyngeal swabs collected from individuals being tested for COVID-19. They confirmed that the RT-LAMP assay was a simpler albeit less sensitive option compared to RT-qPCR for large-scale testing for SARS-CoV-2 RNA. These investigators also developed a simplified version of this method (direct swab–to–RT-LAMP assay) that did not require a prior RNA isolation step as well as a method for highly multiplexed sequencing of RT-LAMP reactions (LAMP-sequencing).","divisions":[{"label":"title","span":{"begin":0,"end":44}}],"tracks":[{"project":"LitCovid-PD-FMA-UBERON","denotations":[{"id":"T4","span":{"begin":31,"end":34},"obj":"Body_part"},{"id":"T5","span":{"begin":477,"end":480},"obj":"Body_part"},{"id":"T6","span":{"begin":714,"end":717},"obj":"Body_part"},{"id":"T7","span":{"begin":850,"end":853},"obj":"Body_part"}],"attributes":[{"id":"A4","pred":"fma_id","subj":"T4","obj":"http://purl.org/sig/ont/fma/fma67095"},{"id":"A5","pred":"fma_id","subj":"T5","obj":"http://purl.org/sig/ont/fma/fma67095"},{"id":"A6","pred":"fma_id","subj":"T6","obj":"http://purl.org/sig/ont/fma/fma67095"},{"id":"A7","pred":"fma_id","subj":"T7","obj":"http://purl.org/sig/ont/fma/fma67095"},{"subj":"T4","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T5","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T6","pred":"source","obj":"LitCovid-PD-FMA-UBERON"},{"subj":"T7","pred":"source","obj":"LitCovid-PD-FMA-UBERON"}]},{"project":"LitCovid-PD-UBERON","denotations":[{"id":"T1","span":{"begin":685,"end":690},"obj":"Body_part"}],"attributes":[{"id":"A1","pred":"uberon_id","subj":"T1","obj":"http://purl.obolibrary.org/obo/UBERON_0002542"},{"subj":"T1","pred":"source","obj":"LitCovid-PD-UBERON"}]},{"project":"LitCovid-PD-MONDO","denotations":[{"id":"T3","span":{"begin":20,"end":28},"obj":"Disease"},{"id":"T4","span":{"begin":112,"end":121},"obj":"Disease"},{"id":"T5","span":{"begin":131,"end":139},"obj":"Disease"},{"id":"T6","span":{"begin":564,"end":572},"obj":"Disease"},{"id":"T7","span":{"begin":703,"end":711},"obj":"Disease"}],"attributes":[{"id":"A3","pred":"mondo_id","subj":"T3","obj":"http://purl.obolibrary.org/obo/MONDO_0005091"},{"id":"A4","pred":"mondo_id","subj":"T4","obj":"http://purl.obolibrary.org/obo/MONDO_0005550"},{"id":"A5","pred":"mondo_id","subj":"T5","obj":"http://purl.obolibrary.org/obo/MONDO_0005091"},{"id":"A6","pred":"mondo_id","subj":"T6","obj":"http://purl.obolibrary.org/obo/MONDO_0100096"},{"id":"A7","pred":"mondo_id","subj":"T7","obj":"http://purl.obolibrary.org/obo/MONDO_0005091"},{"subj":"T3","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T4","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T5","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T6","pred":"source","obj":"LitCovid-PD-MONDO"},{"subj":"T7","pred":"source","obj":"LitCovid-PD-MONDO"}]},{"project":"LitCovid-PD-CLO","denotations":[{"id":"T3","span":{"begin":0,"end":1},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T4","span":{"begin":11,"end":15},"obj":"http://purl.obolibrary.org/obo/UBERON_0000473"},{"id":"T5","span":{"begin":79,"end":83},"obj":"http://purl.obolibrary.org/obo/UBERON_0000473"},{"id":"T6","span":{"begin":275,"end":290},"obj":"http://purl.obolibrary.org/obo/OBI_0000968"},{"id":"T7","span":{"begin":424,"end":430},"obj":"http://purl.obolibrary.org/obo/UBERON_0000473"},{"id":"T8","span":{"begin":553,"end":559},"obj":"http://purl.obolibrary.org/obo/UBERON_0000473"},{"id":"T9","span":{"begin":616,"end":617},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T10","span":{"begin":691,"end":698},"obj":"http://purl.obolibrary.org/obo/UBERON_0000473"},{"id":"T11","span":{"begin":754,"end":755},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T12","span":{"begin":842,"end":843},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"},{"id":"T13","span":{"begin":880,"end":881},"obj":"http://purl.obolibrary.org/obo/CLO_0001020"}],"attributes":[{"subj":"T3","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T4","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T5","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T6","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T7","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T8","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T9","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T10","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T11","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T12","pred":"source","obj":"LitCovid-PD-CLO"},{"subj":"T13","pred":"source","obj":"LitCovid-PD-CLO"}]},{"project":"LitCovid-PubTator","denotations":[{"id":"5","span":{"begin":20,"end":30},"obj":"Species"},{"id":"13","span":{"begin":409,"end":412},"obj":"Gene"},{"id":"14","span":{"begin":101,"end":107},"obj":"Species"},{"id":"15","span":{"begin":131,"end":141},"obj":"Species"},{"id":"16","span":{"begin":142,"end":153},"obj":"Species"},{"id":"17","span":{"begin":703,"end":713},"obj":"Species"},{"id":"18","span":{"begin":112,"end":121},"obj":"Disease"},{"id":"19","span":{"begin":564,"end":572},"obj":"Disease"}],"attributes":[{"id":"A5","pred":"tao:has_database_id","subj":"5","obj":"Tax:2697049"},{"id":"A13","pred":"tao:has_database_id","subj":"13","obj":"Gene:1610"},{"id":"A14","pred":"tao:has_database_id","subj":"14","obj":"Tax:9606"},{"id":"A15","pred":"tao:has_database_id","subj":"15","obj":"Tax:2697049"},{"id":"A16","pred":"tao:has_database_id","subj":"16","obj":"Tax:11118"},{"id":"A17","pred":"tao:has_databa
