Lateral Flow Test

A Lateral Flow Test is a simple diagnostic tool used to quickly detect specific substances, such as viruses or proteins, in a sample, usually from saliva or a nasal swab. It consists of a small device with a test strip that shows results visually, often in the form of colored lines. When the sample is applied, it flows along the strip and reacts with antibodies. If the target substance is present, a line appears, indicating a positive result. These tests are commonly used for rapid COVID-19 screening and are appreciated for their ease of use and quick results.
