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.

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 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 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 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. There are also the 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. 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 passes through that nitrocellulose membrane into the absorbent pad.
