Examples of product developments

The first internationally established product of fassisi in 2008 was the fassisi BoDia, a multi-parameter test for calf diarrhoea, which is easy to use in the barn. With this test, fassisi was the first company to launch a multiple cassette for this field application. further examples are i.a. the fassisi PaG Test (bovine cow-side pregnancy rapid test as international innovation) or the fassisi GiarDia for the detection of Giardia in dogs and cats with the help of latex particles.

Currently fassisi is working on the establishment of new platforms for on-site rapid test systems using mul- tiplex methods or e.g. the use of aptamers and peptide technology.
