What Essential Things You Need to Know Regarding the Lateral Flow Reader
The lateral flow immunoassay or the lateral flow reader is one diagnostic tool or device that is utilized to confirm such presence or absence of that target analyte like those pathogens and biomarkers in the humans or the animals or such contaminants in the animal feeds, the water supplies and the foodstuffs. The very common known type of the lateral flow rapid test is actually the pregnancy test.
LFDs would have such control line for confirming that the test works in the right manner together 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 may be qualitative and also read visually or can be quantitative when they are combined with such reader technology.
Such lateral flow tests are actually used 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 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.
Know that the lateral flow assays may be developed to be used in such dipstick format or can be in a housed cassette. Both of the dipsticks and also the housed tests can work in the same way, it is actually just dependent on the industry, the market requirement and the sample matrix as to what format is actually suitable.
In the sandwich assays, the positive test is actually presented by the presence of such colored line at that test line position. You may also find such competitive assays. The positive test is being represented by the absence of the colored line in the test line position.
The LFDs would make use of such immunoassay technology with the use of the nitrocellulose membrane, those colored nanoparticles or the labels and also the antibodies for producing the results. If a sample is actually added, the sample flows along the test device which would pass through that conjugate pad into the nitrocellulose membrane and then to such absorbent pad.
The sample pad is the first stage in the process of absorption and in some situations would have a filter to make sure that there is such accurate and controlled flow of that sample. Such conjugate pad is going to store the conjugated labels and the antibodies and this receives the sample. The sample would actually pass through such nitrocellulose membrane going into the absorbent pad.
