Article Synopsis
- - This study assessed how accurately SARS-CoV-2 RNA can be detected in saliva samples, comparing those treated with guanidine and without, against traditional nasopharyngeal swabs (NPS) used as a reference.
- - Results showed that raw saliva had a 100% sensitivity for detecting the virus, while the sensitivity for saliva treated with guanidine-based and guanidine-free inactivators was lower, at 65.9% and 82.9% respectively.
- - Despite the reduced sensitivity in treated saliva, the study found that these inactivated samples could still provide reliable results for diagnosing COVID-19, which is beneficial for minimizing the risk of virus transmission.
The reverse transcription polymerase chain reaction (RT-PCR) offers high sensitivity, but has some drawbacks, such as the time required for the RNA extraction. Transcription reverse-transcription concerted reaction (TRC) Ready SARS-CoV-2 i is easy to use and can be performed in about 40 minutes. TRC Ready SARS-CoV-2 i and real-time one-step RT-PCR using the TaqMan probe tests of cryopreserved nasopharyngeal swab samples from patients diagnosed with COVID-19 were compared.

- The study explored the effectiveness of anterior nasal (AN) sampling compared to nasopharyngeal (NP) sampling for diagnosing coronavirus disease using rapid antigen tests.
- Three rapid antigen tests (ESP, LUMI, and LUMI-P) were analyzed for their sensitivity and specificity using samples from 128 symptomatic patients.
- Results indicated that AN sampling had comparable diagnostic accuracy to NP sampling, with no significant factors affecting the agreement between the two methods.
is a gram-negative coccobacillus that is a part of the normal flora in the human upper airway and sometimes causes infective endocarditis. We present a case of a 68-year-old Japanese man who had vascular graft infection caused by 4 years after surgery for chronic aortic dissection.

We used 6 kits available in Japan in 13 NAAT-positive specimens with crossing point values >36 and 7 NAAT-negative specimens from patients with coronavirus disease 2019 (COVID-19), and their results were compared. Specimens positive in ≥2 assays were considered true-positive and examined for concordance with the specimen results.
