The formation of the test line on the strip signifies the presence or absence of an analyte in the sample. At that site, binding reactions take place between analytes and detection molecules. Each lateral flow strip has a functionalized site on the chromatographic membrane, generally in the form of a test line. The applied sample is wicked through the strip by capillary forces. The strips consist of different porous materials that are glued in series on a backing card. A variety of different samples can be used, such as whole blood 1, serum 2, urine 3, saliva 4, milk 5, and many more 6, 7, 8. Lateral flow tests (LFTs) are one of the most common point-of-care tests.
