? Sensitivities CODEX // Cow ?
The table presented below is an indicative list of the sensitivity of the Delvotest® T at control time for the most used antibiotics in the world. This list is not exhaustive. The test is sensitive to many more antibiotic drugs and sulfonamides. Values presented in this list are ppb (parts per billion) equalling μg/Kg or ng/gram.
The best sensitivity is reached when using control time (CT). To test at control time, additionally to the milk you would like to test, perform one additional test with negative control milk, when the test containing the negative control milk turns yellow read the test result of the other milk. The sensitivity of the test when using a fixed reading incubation time (3hr15) can be decreased.
Delvotest® T is not sensitive to quinolones. Quinolones & fluoroquinolones can only be detected at levels much higher than EU MRLs.
* not listed, legislation regulation normally restricts the use: not to be used for lactating animals.
** CCꞵ detection capability is the lowest concentration where a substance can be detected with 95% probability.
Delvotest® T sensitivity listed as CCβ as determined (according to European legislation) by AFNOR validation study 2020-2021.
