Introduction
The emergence of the 2019 novel coronavirus (2019-Ncov) required rapid and accurate diagnostic testing to control the spread of the virus. Speed tests are crucial due to their ability to deliver results promptly, which is essential for timely isolation and treatment.
Testing Procedures
Speed tests for 2019-Ncov primarily involve antigen detection using nasal or throat swabs. These are processed to identify viral proteins, indicating an active infection. Procedures incorporate the following steps:
- Collection of specimen using a sterile swab.
- Insertion of the swab into a liquid reagent for antigen extraction.
- Application of the liquid onto a test cassette or strip.
- Reading the result after 15 to 30 minutes: a positive test is indicated by the presence of a colored line on the test strip.
Technological Components
Speed tests for 2019-Ncov employ lateral flow assay technology, which is cost-effective, quick, and easy to use outside laboratory settings. Key components of the lateral flow tests include:
- Control and test lines impregnated with antibodies specific to 2019-Ncov antigens.
- Conjugated gold nanoparticles for signal visualization.
- Buffer solutions to maintain pH balance and enhance reaction conditions.
