Distributed in the UK by Gem Scientific, Idexx claims that the SNAP ST test for Beta- Lactams is faster and simpler than the original SNAP test.
Earlier tests had to be conducted in two stages involving the use of a heating block, the total test duration being 9 minutes.
With the new SNAP ST test the incubation step is removed, shortening the testing time so that results are available in 6 minutes. Raw milk can be tested directly from a tanker, bulk tank or refrigerator.
Idexx claims the SNAP ST simplifies matters for farmers, who have to test milk for antibiotic residues before dispatch, and tanker drivers and processors, who test the milk when it arrives at the dairy plant.
Additionally, Idexx says that while the SNAP ST test is faster it does not sacrifice any of the sensitivity of the original SNAP test. Furthermore, there is no cross reaction with cleaning chemicals or detergent residues that may be still present on surfaces.
The new test works at the maximum residue level for Beta–Lactams in milk ensuring confidence in the accuracy of results.
Test results from SNAP ST devices can be read visually or automatically using the Idexx SNAPshot DSR Reader.
