The Charm MRLBLTET2A test is an advanced rapid test designed to detect two major antibiotic groups in raw milk: beta-lactams and tetracyclines. With only a 2-minute incubation time for cow's milk and 3 minutes for goat's or sheep's milk, it is the fastest dual residue test available for use on farms and in dairies. This single lateral flow strip screens for penicillins, cephalosporins, and the entire tetracycline family and complies with EU and Codex maximum residue limits.

The test uses Charm's proven ROSA technology, the industry standard used by over 90% of all dairies in Europe. This guarantees accurate, reliable results, whether you're testing on the farm, upon receipt, or in a laboratory. The strip can be read visually or fully automatically with the Charm EZ reader for digital, documented results.

Visual reading is simple. Three lines are present: C (control), BL (beta-lactam), and TE (tetracycline). A negative result is indicated by BL and TE lines that are the same as or darker than the control. A positive result occurs when one or both test lines appear lighter or disappear completely. Invalid strips can be easily identified and retested.

The Charm EZ reader automates interpretation. Insert the strip after incubation, and the device displays a numerical value with the result: negative, BL positive, TET positive, or BLTET positive. Data can be saved or exported, ideal for farms requiring traceability or audit support.

The MRLBLTET2A test helps farmers prevent antibiotic contamination in bulk tanks, avoid rejections, and ensure high-quality milk. The test is suitable for testing individual cows, routine tank inspections, goat and sheep dairy farms, and mixed herds.

Available in kits of 40 and 100 tests, with the 100-test version including positive controls, this test provides rapid, reliable protection for milk safety and compliance with milk regulations.
