Many point-of-care test systems are realized as easy-to-use membrane-based test strips, often enclosed by a plastic test cassette. [2] This concept often is realized in test systems for detecting pathogens, the most common being COVID-19 rapid tests. Very recently such test systems for rheumatology diagnostics have been developed, too. [12]
If patience is not one of your virtues, then the QuickVue at-home COVID test is for you. Each testing kit comes with two full tests — two swabs, two testing strips and two pre-filled solution vials.
Rapid antigen test functioning by lateral flow assay. A typical COVID-19 RAT is a lateral flow test (LFT). [39]: Table S1 [41] For an LFT, a liquid sample (such as from a nasal swab) is placed on a pad at one end of a porous paper-like strip.
The test identified virus in samples of serum, urine, saliva, oropharyngeal swabs and nasopharyngeal swabs. Once commercialized the test has the potential to provide rapid (30-45 minute) diagnosis at point of care. The test was 100% selective and highly sensitive, detecting virus at a concentration of .06 fg/ml. [103]
Fentanyl test strips are small pieces of paper that can detect the presence of fentanyl in many kinds of drugs, including methamphetamine, heroin, cocaine and pills.

A NASA illustration of a lateral flow assay. A lateral flow test (LFT), [1] is an assay also known as a lateral flow immunochromatographic test (ICT), or rapid test.It is a simple device intended to detect the presence of a target substance in a liquid sample without the need for specialized and costly equipment.
For example, it’s totally normal to have low progesterone a day or two after you ovulate—if an egg wasn’t fertilized, it naturally drops which is what leads to a period—but an at-home test ...
