Some Things to Know About the Lateral Flow Reader
Such lateral flow reader or lateral flow immunoassay is a diagnostic device that is used to confirm the absence or presence of target analyte such as the biomarkers and pathogens in the humans or animals or the contaminants in those water supplies, foodstuffs and animal feeds. The really common kind of lateral flow test is called the pregnancy test.
Those LFDs are going to have a control line to be able to confirm that such test works properly along with one or more target or such test lines. They are created to incorporate such intuitive user protocols and require minimal training in order for them to work. They may be qualitative and also read visually or can be quantitative when they are combined with such reader technology.
Lateral flow tests are utilized really popularly in the human health for that point of care testing. They may be performed by the patient or the healthcare professional and also in a range of settings which include the laboratory, home or clinic. In that medical diagnostic industry, there are strict requirements that should be followed for all of those products which were made and manufactured.
Due to that versatile nature, the lateral flow rapid tests are used in different industry sectors which include environmental, veterinary, food and feed as well as the plant and the crop health.
Keep in mind that the lateral flow assays may be created to be used in the dipstick format or may be in the housed cassette. Both the housed tests and the dipsticks may work similarly and it is only dependent on the industry, such market requirement and that sample matrix on what format is best.
In those sandwich assays, positive test is presented by that presence of colored line in its test line position. There are also the competitive assays. The positive test is actually represented by such absence of the colored line at that test line position.
The LFDs make use of such immunoassay technology by using the nitrocellular membrane, those colored nanoparticles or the antibodies and labels to produce the said results. When a sample is added, the sample would flow along the test device passing through such conjugate pad going into the nitrocellulose membrane and into the absorbent pad.
The sample pad would serve as the first stage of such absorption process and in some situations would contain a filter to make sure there is an accurate and also controlled flow of the sample. That conjugate pad would store the conjugated labels and also the antibodies and such would receive the sample. The sample is going to pass through such nitrocellulose membrane going into the absorbent pad.
