Area of Science:

Virology
Infectious Diseases
Diagnostic Technologies

Background:

Over 486 million global COVID-19 cases and 6 million deaths reported.
Mild or asymptomatic infections may constitute 25-80% of all cases, often remaining untested.
Current molecular diagnostic methods like RT-PCR face resource and training limitations.

Purpose of the Study:

To provide a comprehensive review of available COVID-19 diagnostic methods.
To highlight the need for universal testing systems that are specific, sensitive, affordable, easy, portable, and scalable.
To address the challenge of diagnosing mild or asymptomatic infections.

Main Methods:

Review of scientific literature on COVID-19 diagnostic techniques.
Compilation and categorization of various alternative testing strategies.
Analysis of the characteristics of different diagnostic approaches.

Main Results:

Quantitative reverse transcription PCR is the primary molecular diagnostic tool.
Numerous alternative testing methods targeting viral compounds have emerged.
A significant gap remains for universal, accessible, and scalable diagnostic solutions.

Conclusions:

There is an ongoing need for improved COVID-19 diagnostic tools, especially for mild/asymptomatic cases.
Alternative methods show promise but require further development for widespread adoption.
Future diagnostics must balance specificity, sensitivity, cost, and ease of use.
