Rapid Strip Test for Beta-Lactam & Tetracyline Antibotic Residues in Milk

The AuroFlow™ BT Combo Strip Test Kit is a qualitative and rapid lateral flow assay designed to detect both beta-lactam and tetracycline antibiotic residues in raw commingled cow’s milk. This test is designed for rapid field use or reference lab settings. This immunochromatographic assay eliminates the need for a heating block.

The AuroFlow™ lateral flow test strips are designed for the detection of a broad range of antibiotics in raw, commingled cow’s milk. These rapid tests detect 14 beta-lactam antibiotics and 3 tetracyclines in milk at or below EU and CODEX Maximum Residue Limits (MRL). The combo kits allow simultaneous detection of different classes of antibiotic residues.These state-of-the-art tests also use novel methods which eliminate the need for a heating block. Validation reports are available showing the efficacy of the tests in both room temperature and cold milk. The fast, simplified protocol can be seen in the next tab. For visual interpretation, when the signal at the T-line is more intense than the signal at the C-line, the milk sample is negative for presence of residues. A signal at the T-line which is equal to or less intense than the signal at the C-line indicates a contaminated milk sample.

 

This kit is manufactured to the international quality standard ISO 9001:2008.

AuroFlow BT Combo Strip Test Kit Interpretation

The above diagram is for visual interpretation only. If using the QuickSTAR strip reader, refer to reader instructions provided with the unit. If the T-line is less intense than the C-line, the sample is positive for beta-lactam antibiotics.


Invalid Results 

The test is invalid if no colored line appears in the C-line area even if a colored line appears in the T-line area. Re-test milk sample if broken lines are observed. Colored lines which appear after 20 minutes are not diagnostic and should be ignored. If the sample does not flow up the dipstick, the milk sample may be clotted, invalidating the test result. To avoid milk sample clotting, always use fresh raw milk.
