Made primarily of paper Paper is significantly less expensive than other materials typically used in diagnostic devices and is compatible with a variety of existing diagnostic tests. It inherently wicks biological samples through channels patterned in the paper to assay zones, and its mesh-like properties filter the sample of contaminants such as dust and dirt.
Lightweight, durable, and self-contained DFA’s devices can be brought directly to those who are unable to travel to hospitals or clinics and, with no mechanical parts, are robust enough for use even under severe environmental conditions. No auxiliary equipment, electricity, or laboratory facility is needed to use the device or process a sample. Results are quickly displayed, enabling immediate clinical decisions.
Easy-to-use and easy-to-read Minimal training is required to use a DFA device. It is both user-friendly and minimally invasive. A sample from a finger prick is sufficient to yield results. No syringes are involved and neither clean water nor sample preparation is needed. Results are displayed in an easily understood manner, as through a colorimetric scale.
Reliable and Safe Before distribution, devices are packaged so that they are protected from the environment and provide adequate shelf life for transport and storage in the developing world. While DFA devices are single-use, they can be easily and safely disposed of through incineration, assuring that they do not contribute to the global medical waste problem.
“An ideal diagnostic test is ASSURED: affordable, sensitive and specific, user-friendly, rapid and robust, equipment-free, and delivered to those in need.”
