  2. Peak expiratory flow - Wikipedia

    en.wikipedia.org/wiki/Peak_expiratory_flow

    It is classically reduced in obstructive lung disorders such as asthma. Due to the wide range of 'normal' values and the high degree of variability, peak flow is not the recommended test to identify asthma. However, it can be useful in some circumstances. A small portion of people with asthma may benefit from regular peak flow monitoring. When ...

    The patient will be asked to take a deep breath and then blow into the mouthpiece of the spirometer as hard as you can. This is a baseline measurement. A dose of bronchodilator medication is administered by means of inhaler or nebulizer (such as 400mcg of salbutamol (also known as albuterol)).

    The basic forced volume vital capacity (FVC) test varies slightly depending on the equipment used. It can be in the form of either closed or open circuit. Regardless of differences in testing procedure providers are recommended to follow the ATS/ERS Standardisation of Spirometry. The standard procedure ensures an accurate and objectively ...

    The elimination of lab testing can save time and money. An application of a POCT biosensor can be for the testing of HIV in areas where it is difficult for patients to be tested. A biosensor can be sent directly to the location and a quick and easy test can be used. Biosensor implant for glucose monitoring in subcutaneous tissue (59x45x8 mm).

  7. Paper-based biosensor - Wikipedia

    en.wikipedia.org/wiki/Paper-based_biosensor

    One paper-based biosensor that can be used to detect Salmonella, as well as E. coli, uses the nanomaterial graphene. These strips are a form of lateral flow assay, where the test line is composed of fluorescence antibody-labeled CdSe/ZnS quantum dots (Ab-QDs) as probes. After the sample has been applied, graphene oxide is added and it functions ...

  8. Point-of-care testing - Wikipedia

    en.wikipedia.org/wiki/Point-of-care_testing

    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]

  9. Lateral flow test - Wikipedia

    en.wikipedia.org/wiki/Lateral_flow_test

    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.
