Ractopamine LFD Kit for Swine Urine

The Ractopamine LFD is a qualitative one-step competitive inhibition immunoassay for the detection of Ractopamine in animal urine. It detects the presence of Ractopamine at 2.5 ppb or higher concentrations by utilizing highly specific reactions between antibodies and the Ractopamine drug. The test can also be used with chew ropes for ante mortem saliva screening of Ractopamine. The Ractopamine lateral flow device (LFD) is designed solely for use in preliminary screening of undiluted swine urine samples. It is a competitive inhibition immunoassay for the qualitative detection of Ractopamine. The Ractopamine LFD provides only a preliminary qualitative analytical test result. Professional judgment should be applied to any test results, particularly when preliminary positive or negative results are used. LC-MS/MS is recommended as the method of choice for confirmation of positive results obtained with the Ractopamine LFD.
