OneTouch Ultra is a blood glucose monitoring device for people with diabetes that is manufactured by Johnson & Johnson. [1] It is the foundation product for LifeScan's OneTouch Ultra family of blood glucose monitoring systems. OneTouch Ultra blood glucose meters provide blood glucose test results in five seconds.
Immunodiffusion is a laboratory technique used to detect and quantify antigens and antibodies by observing their interactions within a gel medium. [1] This technique involves the diffusion of antigens and antibodies through a gel, usually agar , resulting in the formation of a visible precipitate when they interact.
The transducer is typically separated from the test object by a couplant [4] such as a gel, oil or water, [1] as in immersion testing. However, when ultrasonic testing is conducted with an Electromagnetic Acoustic Transducer (EMAT) the use of couplant is not required. There are two methods of receiving the ultrasound waveform: reflection and ...
LifeScan was established in 1981. [3] It was acquired by Johnson & Johnson (J&J) in 1986, [2] [4] and in June 2018, J&J agreed to sell LifeScan to Platinum Equity as part of its strategic exit from the diabetes device market, accepting an offer originally tendered in March 2018. [1]
The ability to gauge thickness measurement without requiring access to both sides of the test piece, offers this technology a multitude of possible applications. Paint thickness gauges, ultrasonic coating thickness gauges, digital thickness gauges and many more options are available to test plastics, glass, ceramics, metal and other materials.
ATL was later purchased by Philips while Sonosite came out with its first battery powered portable offering, the Sonosite 180 released in 1998. [2] Previous to this, Ecton produced a low-cost portable cardiac ultrasound system that could be carried by hand in March 1998, called the Sonnet [ 3 ] but the test prototypes were never put into full ...
A gel plate is cut to form a series of holes ("wells") in an agar or agarose gel. A sample extract of interest (for example human cells harvested from tonsil tissue) is placed in one well, sera or purified antibodies are placed in another well and the plate left for 48 hours to develop.
Blood compatibility testing is routinely performed before a blood transfusion.The full compatibility testing process involves ABO and RhD (Rh factor) typing; screening for antibodies against other blood group systems; and crossmatching, which involves testing the recipient's blood plasma against the donor's red blood cells as a final check for incompatibility.
