What Essential Things You Need to Know Regarding 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 very common known type of the lateral flow rapid test is actually 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.
Those lateral flow tests are widely used in such human health for such point of care testing. They can actually be performed by the patient or that healthcare professional and in several settings including the laboratory, home or the clinic. In such medical diagnostic industry, there are such strict requirements in its regulation which should be observed to for all the products that were developed as well as manufactured.
Because of such versatility in nature, the lateral flow rapid tests are being used in a lot of industry sectors that would include food and feed, veterinary, environmental and also the plant and crop health.
You have to know that such lateral flow assays can be made to be used in that dipstick format or it may also be in that 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. You may also find such competitive assays. A positive test is actually presented by the absence of a colored line in such 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 is actually the first stage in such absorption process and in some situations come with a filter to ensure that there is that accurate as well as controlled flow of the sample. The conjugate pad is going to store the conjugated labels as well as the antibodies and this is going to receive the sample. The sample would actually pass through such nitrocellulose membrane going into the absorbent pad.
