Laboratory and Point-of-Care Testing for COVID-19: A Review of Recent Developments

Area of Science:

• Virology
• Epidemiology
• Public Health

Background:

• The emergence of Coronavirus Disease 2019 (COVID-19) necessitated rapid diagnostic strategies for effective containment and mitigation.
• The initial lack of widespread contact tracing exacerbated the global spread of the virus, highlighting the need for accessible testing.
• The development of rapid COVID-19 testing has been instrumental in lessening infection rates and enabling a gradual return to normalcy.

Purpose of the Study:

• To review various antibody, antigen, and molecular tests for COVID-19.
• To discuss tests that have received emergency authorization (EA) from the Food and Drug Administration (FDA).
• To analyze point-of-care tests, including their specificity and sensitivity.

Main Methods:

• Literature review of diagnostic tests for COVID-19.
• Analysis of Food and Drug Administration (FDA) emergency authorizations (EA).
• Evaluation of test characteristics, including specificity and sensitivity for various testing platforms.

Main Results:

• Discussion of diverse COVID-19 testing methodologies: antibody, antigen, and molecular assays.
• Overview of FDA-authorized rapid diagnostic tests and point-of-care (POC) options.
• Examination of the diagnostic accuracy, sensitivity, and specificity of different testing kits.

Conclusions:

• Appropriate and widespread testing is essential for understanding COVID-19 transmission dynamics.
• Diagnostic test performance, including specificity and sensitivity, is critical for accurate prevalence assessment.
• Continued monitoring and utilization of diverse testing strategies are vital for managing the ongoing pandemic and future public health challenges.
