35.1% of infections being asymptomatic, a 24-h delay in obtaining RT-PCR test results, no delay in receiving rapid antigen test results, an incubation period of 4.4 days, self-isolation upon symptom onset, and the diagnostic sensitivity curve for RT-PCR based on data from Hellewell et al11,...
Rapid antigen test (RAT) done on similarly collected swab samples has emerged as an alternative testing strategy with the advantages of requiring less resources and offering quick results. We have analysed the trends of RAT results in our centre which is a nodal centre for Covid-19 diagnosis ...
Self-testing is an effective tool to bridge the testing gap for several infectious diseases; however, its performance in detecting SARS-CoV-2 using antigen-detection rapid diagnostic tests (Ag-RDTs) has not been systematically reviewed. This study aimed to inform WHO guidelines by evaluating the ...
At the present time, there are a number of serological tests for porcine cysticercosis that have been published and were originally claimed to offer sensitive and specific diagnosis of porcine cysticercosis, in particular the apDia circulating antigen test developed at the Institute of Tropical Medicine...
The advanced HIV rapid diagnostic tests such as determine TB urine lipoarabinomannan lateral flow assay (urine LAM), urine X-pert MTB/RIF assay (urine X-pert), and serum/blood cryptococcal antigen test (serum CrAg) are recommended but frequently not available in many resource-limited set- ...
[such as microscopy and quantita- tive buffy coat (QBC) test], through identifying parasite nucleic acids by molecular methods [such as PCR, loop- mediated isothermal amplification (LAMP) method, microarray] or parasite specific antigens/antibody by rapid diagnostic tests and other new strategies ...
Nevertheless, RDTs still have some limitations including the inability to detect mixed infections, all species of Plasmodium, infections at low concentrations of parasites, along with an inability to monitor response to therapy and false positives due to the presence of the malaria antigen even after...
We evaluated the performance of oral swab specimen both health-care worker (HCW) collected and self-collected for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) detection with rapid antigen test (RAT) as compared to reverse transcriptase po
Chikungunya virus (CHIKV), a mosquito-borne pathogen, consists of three genotypes: East/Central/South African (ECSA), West African (WA), and Asian. Although a current rapid immunochromatographic (IC) test detecting CHIKV E1-antigen showed high sensitivit
10, 2020, file photo, a health worker inside a mobile lab takes nasal swab sample for a COVID- 19 antigen test in New Delhi, India. In June, India began using the cheaper, faster but less accurate tests to scale up testing for the coronavirus—a strategy that the U.S. is now ...
