Comparison of Rapid Antigen Test and PCR Test Oct 26, 2021

The Rapid Antigen Test Kit provides rapid results for fast detection of Sras-Cov-2 antigen

  • The Rapid Antigen Test allows getting a quick result within 15-30 minutes, no need for a follow-up appointment to discuss the result.
  • Milti sample collection swab available for Lateral Flow Test: Nasopharyngeal swabs, anterior nasal swab, Oropharyngeal swabs, oral swab, sputum, etc.
  • Lateral Flow Test allowing decentralized testing or access to testing in areas where laboratory testing is not available.
