The Charm MRLBL test is a rapid and reliable lateral flow test designed to detect beta-lactam antibiotics in raw, mixed cow's milk. This group includes some of the most commonly used treatments in dairy farming, such as penicillin, amoxicillin, ceftiofur, cephapirin, and many others. The test is widely recognized as the industry standard and is used by over 90% of all dairy farms in Europe for routine screening of incoming milk.
The MRLBL test is based on Charm's proven ROSA (Rapid One-Step Assay) technology and delivers accurate results that meet or exceed EU and Codex MRL limits. From farm to processing plant, this test provides reliable antibiotic testing in just 8 minutes, preventing unintended contamination, costly milk rejections, and loss of premiums for premium quality.
The test can be read visually or interpreted digitally using the ROSA Reader or Charm EZ system. Visual interpretation is simple: a negative result is indicated by a test line (T) that is equal to or darker than the control line (C). A positive result is indicated by a T line that is lighter, irregular, or absent. The strip design provides clear, easy-to-read lines for confident decision-making in any farm environment.
When used with the EZ/ROSA reader, the test strip is automatically analyzed. The device provides a numerical result along with a clear interpretation of Negative or Positive. Results can be saved, printed, or transferred to a computer, making it ideal for farms and dairies that require documented data for compliance or audits.
The Charm MRLBL test is suitable for a wide range of applications, including bulk tank testing, individual cow monitoring after treatment, on-farm verification prior to collection, and screening on dairy farms. The test maintains high sensitivity even at low antibiotic concentrations and offers excellent reliability with minimal training.
The MRLBL test is available in 40- and 100-test formats and provides reliable daily protection for milk quality and compliance throughout the dairy chain.
