Lateral flow tests can be run both qualitatively and quantitatively. A qualitative test only examines the sample for the presence or absence of a specific analyte and can be read with the naked eye and the positive/negative result is enough. Pregnancy test is a good example of it.
However, in many day-to-day decisions, it is not enough to just obtain the “yes” or “no” answer. Oftentime, it comes down to the amount of constituents of the sample. This is where we come to talk about the quantitative testing. We decided to give this field of activity the recognition it deserves and compiled a list of FAQs that often come up in this respect.
