Some Things to Know About the Lateral Flow Reader
The lateral flow reader or the lateral flow immunoassay is one diagnostic device which is utilized for confirming the presence or the absence of such target analyte like the pathogens and the biomarkers in the animals or humans or the contaminants in the water supplies, the animal feeds and the foodstuffs. The pregnancy test is one kind of lateral flow rapid test which is quite common.
The LFDs would contain a control line in order to confirm that the test is indeed working well along with one or more target or those test lines. They are made for incorporating intuitive user protocols and also need minimal training for them to operate. They can also be qualitative and read visually or may be quantitative if such is combined with the reader technology.
Those lateral flow tests are widely used in such human health for such point of care testing. They can be done by the patient or such healthcare professional and in various settings that would include clinic, home or laboratory. In that medical diagnostic industry, there are strict requirements that should be followed for all of those products which were made and manufactured.
Because of their versatile nature, such lateral flow rapid tests are being used across several other industry sectors that include veterinary, environmental, food and feed and also the plant and 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 the sandwich assays, the positive test is actually presented by the presence of such colored line at that test line position. On the other hand, there are those 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. If a sample would be added, the sample is going to flow along such test device passing through that conjugate pad into that nitrocellulose membrane and going to 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. Such conjugate pad is going to store the conjugated labels and the antibodies and this receives the sample. The sample is going to pass through such nitrocellulose membrane going into the absorbent pad.
