Previous research on SARS-CoV-2 infection has determined optimal timing for testing in quarantine and the utility of different frequencies of testing for infection surveillance using RT-PCR and generalized rapid antigen tests. However, these strategies can depend on the specific rapid antigen test used...
RT-PCR = reverse transcriptase polymerase chain reaction; Ag-RDT = antigen rapid diagnostic testing; LTCF = long-term care facility. Full size image Cost-effectiveness of surveillance interventions varied by orders of magnitude across LTCFs (Fig. 4). In LTCF 1, assuming baseline per-test unit ...
Figure 1shows the distribution of rapid diagnostic test results obtained on fingerstick testing at point of care versus real-time RT-PCR results obtained in the reference laboratory. No invalid rapid diagnostic test results were observed in point-of-care testing; one RT-PCR test failed (ie, the...
All differences in sensitivity between the four RDTs were significant except for the Coris® EBOLA Ag K-SeT versus Standard® Q Ebola Zaïre Ag (p = 0.16). The p-value between QuickNavi-Ebola™ and OraQuick® Ebola Rapid Antigen was 0.03, all others were <0.0001. Despite the ...
Rapidity versus riability: Critical analysis of polymerase chain reaction (PCR) as a new rapid diagnostic technique in mycobacterial infectionsTintelnot, KKirchner, PSchmidt, MBottger, E CHeesemann, J
The study from Nigeria found that the Diazo reagent had 27.3% sensitivity when compared to the Widal test [184]. (Additional file 3: Table S2: Details of included studies). Schistosomiasis Three studies on schistosomiasis evaluated circulating cathodic antigen (CCA) immunochromatographic tests (Rapid...
All patients that tested positive to microscopy also tested positive to RDTs based on antigen. All patients on the second day of follow-up were non-febrile and had antimalaria drugs. We conclude based on the present study that the RDTs based on malaria antigen (whole blood) method is as ...
an enrichment step was explored as an addendum to the initial steps of the method to improve analytical sensitivity for microbial DNA and efficiency of host depletion. Both arms of the protocol (i.e., the standard protocol without an enrichment step, versus the protocol with an enrichment addend...

rapid antigen tests by meta-regression and hierarchical summary receiver operating characteristic model. This level of accuracy was consistent across several subgroup analyses, including the type of antigen test, age, country, and exposure to antibiotics. The sensitivity was slightly high in low-income...
