Nano-Check TM COVID-19 Antigen Test

Nano-CheckTM COVID-19 Antigen Test is designed to detect the extracted nucleocapsid antigen specific to SARSCoV-2 in nasopharyngeal swab specimens directly collected or collected in viral transport media from individuals who are suspected of COVID-19 by their healthcare provider within the first five days of symptom onset.

  • Sensitivity: 85.0%, Specificity: 100.0%
  • Instant results in 15 minutes
  • No equipment required
  • Detection
  • Room temperature storage (2-30℃)

Interpretation

• Negative:
A single pinkish red colored band at the control line (C) with the absence of band at test line (Ag) is a negative result for SARS-CoV-2 virus.
Negative result does not indicate the absolute absence of SARS-CoV-2 virus in specimen.
Instead, it only indicates that the specimen contains the SARS-CoV-2 virus titer at below the detectable level.
• Positive:
Appearance of pinkish red colored bands at both control line (C) and the test line (Ag) indicates that the SARS-CoV-2 virus was detected.
• Invalid:
If no colored line appears in the control line (C), the test result is invalid. The test result is inconclusive, and the assay should be repeated with a new test cassette.
