The Power of Tracers in Lateral Flow

Lateral Flow Immunoassays (LFIA) are based on the migration of nano or micro particles on strips for analytes detection. These tests, strips or cassettes (example: the pregnancy test) are widely used as first-line emergency tests performed at the patient’s bedside or directly in the field, thanks to its user-friendly design.

LFIA test can be used in different applications (Human health, Animal health, Drug presence assessment, Industrial quality control, Agriculture, Biosecurity, Environment, etc.) and with different types of samples (serum, plasma, urine, saliva, food, environmental media, water, etc.).

Although a Lateral Flow test is easy to use, it is based on a sophisticated device made up of several components including the tracer or conjugate used as a detection agent.

There are different types of conjugates, and the choice of the right one is important for test performance (sensitivity, specificity, stability, etc.).
