Nose or Throat？What’s Best for a COVID Test? In the early days of the pandemic, public health officials scrambled to get a read on the new viral outbreak. The CDC covered all its bases, recommending specimens be sent to them in three ways for each person: from the back of their throat (oral-pharyngeal), deep into their nasal passage (nasopharyngeal), and from sputum.

Evaluation of COVID‑19 Antigen Fluorescence Immunoassay Test for Rapid Detection of SARS‑CoV‑2

COVID‑19 Antigen Fluorescence Immunoassay, Tests detecting SARS‑CoV‑2‑specific antigen have recently been developed, and many of them are now commercially available. However, the real‑world performance of these assays is uncertain; therefore, their validation is important. In this study, we have evaluated the performance of STANDARD F COVID‑19 antigen fluorescence immunoassay (FIA) kit. Methods: Nasopharyngeal samples collected from patients were subjected to the test as per manufacturer’s instructions. The performance of the kit was compared with the gold standard real‑time polymerase chain reaction. Results: A total of 354 patients were tested with STANDARD F COVID‑19 antigen FIA test kit. The overall sensitivity, specificity, positive predictive value, and negative predictive value of this test were found to be 38%, 99%, 96.2%, and 72%, respectively, with a diagnostic accuracy of 75.7%. Conclusion: STANDARD F COVID‑19 antigen FIA showed high specificity and positive predictive value but low sensitivity and negative predictive value Read more
