Advances in Rapid Diagnostic Testing for Infectious Diseases

Rapid diagnostic testing has become increasingly important in the fight against infectious diseases, enabling faster diagnosis and treatment initiation, particularly in resource-limited settings.

Types of Rapid Diagnostic Tests

Immunochromatographic Tests (ICT)

These lateral flow assays detect antigens or antibodies and provide results in 15-30 minutes. Common applications include:

• Malaria rapid tests
• HIV screening tests
• Pregnancy tests
• COVID-19 antigen tests

Molecular Point-of-Care Tests

Portable PCR and isothermal amplification devices bring molecular testing to the point of care:

• GeneXpert for TB diagnosis
• FilmArray for respiratory pathogens
• Portable PCR systems

Advantages of Rapid Testing

• Faster time to results (minutes vs. hours/days)
• Minimal equipment requirements
• Can be performed in non-laboratory settings
• Enables immediate treatment decisions
• Reduces sample transport challenges

Quality Considerations

While rapid tests offer convenience, laboratories should:

1. Select validated tests with appropriate sensitivity/specificity
2. Follow manufacturer instructions precisely
3. Implement quality control programs
4. Train staff on proper test performance
5. Confirm positive results when indicated
