Rapid diagnostic testing platform for iron and vitamin A deficiency

Area of Science:

• Biochemistry
• Public Health
• Medical Diagnostics

Background:

• Micronutrient deficiencies (Vitamin A, iron) impact a third of the global population, causing severe health issues.
• Current diagnostic methods are often inadequate, inaccessible, or unaffordable, hindering intervention efforts.
• Accurate and accessible diagnostics are crucial for effective nutritional status assessment and monitoring.

Purpose of the Study:

• To develop a rapid, simultaneous diagnostic test for iron, vitamin A, and inflammation status.
• To create a mobile-enabled platform for point-of-care assessment in diverse settings.
• To improve the targeting and effectiveness of interventions for micronutrient deficiencies.

Main Methods:

• Combined multiple fluorescent markers and immunoassay techniques on a single test platform.
• Developed a rapid quantification method for ferritin, retinol-binding protein, and C-reactive protein.
• Integrated the test with a mobile-enabled platform for data reading and analysis.

Main Results:

• Achieved accurate quantification of iron, vitamin A, and inflammation markers within 15 minutes.
• Reported high diagnostic accuracy: sensitivities of 88-100% and specificities of 97-100%.
• Demonstrated suitability for point-of-care use in both resource-rich and limited settings.

Conclusions:

• The developed diagnostic platform offers a transformative solution for global nutritional status assessment.
• Enables rapid, accurate, and accessible screening for key micronutrient deficiencies and inflammation.
• Has the potential to significantly improve public health outcomes by enabling targeted interventions.
