BETA-AGONIST FAST URINE ELISA
The Randox Food Diagnostics Beta-Agonists FAST ELISA test kit detects 12 Beta-Agonists compounds within a urine sample using direct application. This method allows for an exceptional time to result of 40mins, instead of the standard ELISAs 1hr 45min.
Beta-agonists have chemical structures, similar to the naturally occurring catecholamines, adrenaline and noradrenaline. They were originally produced for the treatment of respiratory diseases such as asthma. Beta-agonists facilitate the use of fats rather than glucose as a fuel source. This improves the meat: fat ratio of animals and leads to the production of higher quality meat at lower cost. The use of Beta-agonists as growth promoters has been banned in most countries. Consequently, reliable screening and testing methods are important to ensure that traces of these residues do not enter the food chain.
