Dairy Testing - Beta-lactam and Tetracyline Detection Strips

AuroFlow™ Test Strips are lateral flow tests for the detection of antibiotics in Milk:


AuroFlow Beta-Lactam Test Strips for the detection of a broad range of beta-lactam antibiotics including ampicillin, penicillin G, amoxicillin, cloxacillin, oxacillin and cephalosporins (i.e. cefoperazone, ceftiofur, etc).


AuroFlow BT Combo Test Strips for the detection of both beta-lactam AND tetracycline antibiotic residues.


AuroFlow BTS Combo Test Strips for the detection of beta-lactam, tetracycline and sulfonamide antibiotic residues.


Also these tests have been externally validated by the Chemical Surveillance Branch of the Agri-Food and Biosciences Institute, Belfast.


These state-of-the-art tests use a tetracycline receptor and a novel beta-lactam binding protein eliminating the need for a heating block and because they do not require any equipment, they are ideal for use in the field or at a farm. Also they have a very simple and rapid protocol (shown on the right) that provides results in under 10 minutes.


Simple Interpretation of Results:

Each test strip is imprinted with either one or two test lines and one Control line (C-line). One test line allows for the detection of beta-lactam antibiotics and in the case of the BT Combo Strip the other test line allows for the detection of tetracyclines.

When the signal at the test lines are more intense than the signal at the C-line, the milk sample is negative for presence of the relevant antibiotics. A signal at the either test line which is equal to or less intense than the signal at the C-line indicates the presence of antibiotics in the milk sample.
