Charm Quinolone Test (QUIN)

SKU:N/A Category:


In three minutes, the Charm ROSA QUIN test detects 11 quinolone drugs in milk. The QUIN test is run by farmers, veterinarians, truck drivers, milk receiving, and milk testing laboratories because of its speed, ease of use, portability, and minimal equipment requirements.

This 3-minute Rapid One Step Assay is performed with a lateral flow strip in the Charm EZ system. Add sample to the EZ system, close the door, and the sample will be automatically read as negative or positive. The test also can be performed with a ROSA incubator and read on the ROSA Pearl-X Reader.

Lower operating costs and improve transportation efficiency by clearing good milk quickly with the Charm ROSA (Rapid One Step Assay) lateral flow strips, which detect aflatoxin M1 and the most common antibiotics used to treat dairy cows. ROSA tests use patented technology to target drug sensitivities to safe and regulated levels, which prevents unnecessary rejection of milk caused by overly sensitive screening tests. The tests are easy to perform and are manufactured to test for US Safe Levels, EU MRL/ CODEX/ Customs Union Maximum Residue Limits and multiple other country-specific requirements. Charm ROSA tests have been granted approval by regulatory authorities around the world.

Test results from ROSA strips may be read and officially recorded using the Charm EZ system, or the ROSA Pearl-X Reader, or may be interpreted visually in an unofficial capacity, making it ideal for farm use.
