Insights

Lateral flow assays (LFAs) are crucial for monitoring COVID-19 transmission and immunity. This review evaluates their accuracy and implementation for pandemic control, especially in resource-limited settings.

Area of Science:

  • Infectious Diseases
  • Immunology
  • Public Health

Background:

  • The COVID-19 pandemic, caused by SARS-CoV-2, has led to widespread health and economic challenges.
  • Monitoring viral transmission and antibody longevity is essential for pandemic control.
  • Serologic assays are vital for assessing population immunity after infection or vaccination.

Purpose of the Study:

  • To review the role of serologic lateral flow assays (LFAs) in monitoring COVID-19.
  • To discuss the evaluation of LFA accuracy and suitability for various applications.
  • To explore implementation opportunities for LFAs in pandemic surveillance.

Main Methods:

  • Review of existing literature on serologic lateral flow assays for SARS-CoV-2.
  • Discussion of criteria for evaluating LFA performance characteristics.
  • Analysis of LFA applications in population surveillance and individual testing.

Main Results:

  • LFAs offer affordable and scalable solutions for detecting anti-SARS-CoV-2 antibodies.
  • These assays are valuable for tracking seroprevalence and understanding herd immunity.
  • LFAs are particularly important for monitoring immunity durability in diverse settings.

Conclusions:

  • Serologic LFAs are critical tools for managing the ongoing COVID-19 pandemic.
  • Accurate evaluation and strategic implementation of LFAs can inform public health strategies.
  • LFAs support monitoring of natural and vaccine-induced immunity, crucial for long-term control.
