KIS Test
>> Available in kits of 25 and 100 tests

The Charm Kidney Inhibition Swab (KIS) is a simple to use inhibition test for screening broad-spectrum antimicrobial drugs in fresh or thawed kidney tissue. The KIS Test has been chosen by the USDA Food Safety and Inspection Service (FSIS) for use by USDA inspectors at slaughter facilities to screen for sulfonamides and antibiotic drugs under the National Residue Program (NRP). A modified procedure allows the KIS Test to be applied to poultry serum, animal feed, beef and porcine urine, and water.

KIS reagents are self-contained, solvent-free, and pre-measured in a single use, disposable swab format. Results take approximately 3 hours. Speed, sensitivity, and simplicity make the KIS an ideal antibiotic test for the meat industry.

The starting color in the KIS vial is blue/purple. When microbial inhibitors (e.g., antibiotics) are present in the sample being tested, microbial growth in the KIS vial is inhibited which prevents a color change to yellow. Thus positives remain blue/purple.
