The following article describes what a lateral flow immunoassay is used for. In addition, the article explains the different component parts used during manufacturing in order to make them work.
Common Names For a Lateral Flow Immunoassay
Different industry sectors and different countries use varying terminology to describe a lateral flow immunoassay. Common names include:
- Lateral flow test (LFT)
- Lateral flow device (LFD)
- Lateral flow assay (LFA)
- Lateral flow immunoassay (LFIA)
- Lateral flow immunochromatographic assays
- Express test
- Pen-side test
- Quick test
- Rapid test
- Test strip
What is a lateral flow immunoassay?
So, what is a lateral flow immunoassay? Basically, it is a simple to use diagnostic device used to confirm the presence or absence of a target analyte, such as pathogens or biomarkers in humans or animals, or contaminants in water supplies, foodstuffs, or animal feeds. The most commonly known type of lateral flow rapid test strip is the pregnancy test.
LFDs typically contain a control line to confirm the test is working properly, along with one or more target or test lines. They are designed to incorporate intuitive user protocols and require minimal training to operate. They can be qualitative and read visually, or provide data when combined with reader technology, such as AppDx®.
Lateral flow tests are widely used in human health for point of care testing. They can be performed by a healthcare professional or by the patient, and in a range of settings including the laboratory, clinic or home. In the medical diagnostic industry, there are strict regulatory requirements which must be adhered to for all products developed and manufactured and Abingdon Health can guide you through this process.
Due to their versatile nature, lateral flow rapid tests are used across a number of other industry sectors including pharma, environmental testing, animal health, food and feed testing, and plant and crop health.
Types Of Lateral Flow Tests
Lateral flow assays can be developed to be used in a dipstick format or in a housed cassette. Both dipsticks and housed tests will work in a similar way, it is just dependent on the industry, sample matrix, and the market requirement, as to which format is suitable.
Sandwich assays – A positive test is represented by the presence of a coloured line at the test line position.
Competitive assays – A positive test is represented by the absence of a coloured line at the test line position. get SARS-CoV-2 Antigen Rapid Test United Kingdom.
