Important Things to Understand 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 made for incorporating intuitive user protocols and also need minimal training for them to operate. They may actually be qualitative and also read visually or can be quantitative if this is used with the 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 such medical diagnostic industry, there are those strict regulatory requirements that should be followed for all of the products which were developed and also 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.

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. A positive test is actually presented by the absence of a colored line in such test line position.

LFDs are going to use the immunoassay technology through the use of the nitrocellular membrane, the colored nanoparticles or such labels and the antibodies for producing those 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 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.
