Charm Sulfa Test detection levels meet or exceed the US FDA Safe Level and Canadian MRL of 10 ppb for most sulfa drugs. The FDA has banned the use of certain sulfa drugs like sulfamethazine in animals because they are known secondary carcinogens in mice. Using a simple dilution procedure, the Charm Sulfa Test detection level may be adjusted to meet the EU MRL of 100 ppb total sulfa drugs.
"By enabling multiple sulfonamides to be detected with a simple all-in-one test test, Charm customers gain the added security of knowing that they will pick up any member of the sulfonamide family," said Meikel Brewster, vice president of sales at Charm Sciences.
Charm Sulfa Test uses Charm's patented ROSA® (Rapid One Step Assay) technology, combining fast, accurate detection with ease of use. Simply add milk to the test strip, incubate for 8 minutes and read on the ROSA Reader. The ROSA Reader stores results electronically for data capture, record keeping, and reporting.
Charm Sulfa Test joins the Charm family of ROSA milk tests, the leading residue diagnostic tests employed by the dairy industry worldwide. Other ROSA milk tests detect beta-lactams, tetracyclines, enrofloxicin, chloramphenicol and aflatoxin M1. Combination beta-lactam/tetracycline kits are also available. Charm produces separate test kits to meet US, European, and other regulatory requirements. All ROSA tests can use the same incubator and reader.
