Abstract
BACKGROUND SARS-CoV-2 virus originated in Wuhan (China) in December (2019) and quickly spread worldwide. Antigen tests are rapid diagnostic tests (RDT) that produce results in 15-30 min and are an important tool for the scale-up of COVID-19 testing. COVID-19 diagnostic tests are authorized for self-testing at home in some countries, including Brazil. Widespread COVID-19 diagnostic testing is required to guide public health policies and control the speed of transmission and economic recovery. METHODS Patients with suspected COVID-19 were recruited at the Hospital da Baleia (Belo Horizonte, Brazil). The SARS-CoV-2 antigen-detecting rapid diagnostic tests were evaluated from June 2020 to June 2021 using saliva, nasal, and nasopharyngeal swab samples from 609 patients. Patient samples were simultaneously tested using a molecular assay (RT-qPCR). Sensitivity, specificity, accuracy, and positive and negative predictive values were determined using the statistical program, MedCalc, and GraphPad Prism 8.0. RESULTS The antigen-detecting rapid diagnostic tests displayed 98% specificity, 60% sensitivity, 96% positive predictive value, and moderate concordance with RT-qPCR. Substantial agreement was found between the two methods for patients tested < 7 days of symptom onset. CONCLUSIONS Our findings support the use of Ag-RDT as a valuable and safe diagnostic method. Ag-RDT was also demonstrated to be an important triage tool for suspected COVID-19 patients in emergencies. Overall, Ag-RDT is an effective strategy for reducing the spread of SARS-CoV-2 and contributing to COVID-19 control.

Serological tests using Sporothrix species antigens for the accurate diagnosis of sporotrichosis: a meta-analysis. Diagn Microbiol Infect Dis 2020; 98:115131.

Abstract
Some species of the fungus Sporothrix cause a chronic granulomatous infection in humans and animals called sporotrichosis. In the last decades, some research into serological tests has been carried out by different groups for the rapid detection of this infection. We performed a systematic review of the literature with meta-analysis to evaluate studies using Sporothrix spp. antigens and to evaluate their accuracy for sporotrichosis diagnostic. We searched Scopus, MEDLINE, Web of Science, GALE, Technology Research Database, DOA, Elsevier, SciELO, and Google Scholar Databases. The united results of sensitivity, specificity, positive and negative likelihood ratios, and diagnostic odds ratio with their corresponding 95% confidence intervals (CI) were assessed. A total of 15 assays from 8 studies using 7 different serological methods and 8 different antigens were analyzed. The studies were performed in the USA, Brazil, and Venezuela from 1973 until 2015 and presented good quality. A high heterogeneity for sensitivity [I2 = 90.7%; 87% CI = (84-89), P < 0.001] and specificity [I2 = 89.2%; 93% CI = (92-95), P < 0.001] was observed. The performance of diagnostic tests was 0.93. Enzyme-linked immunosorbent assay was the main tool used, and the ConA-binding fraction antigen of the strain 1099-18 appears as a promising diagnostic biomarker candidate.
