The current study is the first meta-analysis comparing the overall sensitivity, and specificity of newly developed ultrasensitive <jats:italic>Plasmodium falciparum<\/jats:italic> malaria RDT (Alere\u2122 Ultra-sensitive Malaria Ag P. <jats:italic>falciparum<\/jats:italic> RDT) with the cRDT conducted in the same field conditions.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>PubMed, EMBASE, Cochrane infectious diseases group specialized register, and African Journals Online (AJOL) were searched up to 20<jats:sup>th<\/jats:sup> April 2021. Studies with enough data to compute sensitivity and specificity of uRDT and cRDT were retrieved. A random-effect model for meta-analysis was used to obtain the pooled sensitivity and specificity.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Overall, 15 data sets from 14 studies were included in the meta-analysis. The overall sensitivity of the Alere\u2122 ultra-sensitive Malaria Ag <jats:italic>P. falciparum<\/jats:italic> RDT regardless of the reference test and the clinical presentation of participants, was 55.5% (95% confidence interval [CI]: 45.5; 65.0), while the sensitivity regardless of the reference test and the clinical presentation of participants, was 42.9% (95% CI: 31.5; 55.2) for the cRDT performed in the same field conditions. When PCR was used as reference test, the sensitivity of uRDT was 60.4% (95% CI: 50.8; 69.2), while the sensitivity was 49.4% (95% CI: 38.2; 60.6) for the cRDT. The pooled specificity of uRDT regardless of the reference test and the clinical presentation of participants was 98.6% (95% CI: 97.1; 99.4), and the pooled specificity of cRDT regardless of the reference test and the clinical presentation of participants was 99.3% (95% CI: 98.1; 99.7). When PCR was used as reference test the specificity of uRDT and cRDT was 97.5% (95% CI: 94.1; 98.9) and 98.2% (95% CI: 95.5; 99.3). Regardless of the reference test used, the sensitivity of Alere\u2122 Ultra-sensitive Malaria Ag <jats:italic>P. falciparum<\/jats:italic> RDT in symptomatic patients was 72.1% (95%CI: 67.4; 76.4), while sensitivity of cRDT was 67.4% (95%CI: 57.6; 75.9).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Findings of the meta-analysis show that Alere\u2122 Ultra-sensitive Malaria Ag <jats:italic>P. falciparum<\/jats:italic> RDT compared to cRDT performed in the same field conditions has higher sensitivity but lower specificity although the difference is not statistically significant.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s12936-021-03783-2","type":"journal-article","created":{"date-parts":[[2021,6,3]],"date-time":"2021-06-03T12:04:21Z","timestamp":1622721861000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["Assessing field performance of ultrasensitive rapid diagnostic tests for malaria: a systematic review and meta-analysis"],"prefix":"10.1186","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7976-4331","authenticated-orcid":false,"given":"Celestin","family":"Danwang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fati","family":"Kirakoya-Samadoulougou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sekou","family":"Samadoulougou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,6,3]]},"reference":[{"key":"3783_CR1","unstructured":"WHO.
