The SNAP Beta-Lactam ST Plus Test and the SNAPduo ST Plus Test contain a proprietary reformulated conjugate pellet that accurately and reliably detects beta-lactam and tetracycline antibiotic residues including cephalexin without heat or incubation, allowing you to test cold milk directly from the truck, refrigerator or bulk tank. The IDEXX SNAP Beta-Lactam ST Plus Test performance has been validated by an independent lab (ILVO).
SNAP ST Plus tests are completed in less than 7 minutes.
To achieve optimal results close to the Maximum Residue Limits, using a heater block is not recommended. If a heater block is used by mistake, follow the prescribed protocol to retest the sample without the heater block.
Tests that were taken out of refrigeration to be used during the day may be returned to refrigeration as long as the room temperature during the day did not exceed 30°C.
For optimal results, run the test on a flat, level surface.
Refrigerate all SNAP test materials at 2–8°C (36–46°F). Tests can be kept at 15-30°C (59-86°F) during the day of use. SNAP ST Plus tests may be stored at 15–22°C (59–72°F) for up to 30 days. Check labeling for test-specific instructions. Remove only the number of tests to be used for the day.
Yes, the test is designed for use under normal ambient conditions (15–30°C). Remove the number of devices needed for the day from refrigeration and allow them to warm to room temperature for at least 15 minutes before using.
Before you test:
- Verify that the SNAP device has colored spots in the results window and activation circle.
- Make sure the pellet is moving freely in the bottom of the sample tube.
After the reagent pellet has dissolved, pour the entire contents of the sample tube into the sample well of the SNAP device. Remain with the device and watch the sample flow across the results window toward the blue activation circle. When the blue activation circle begins to disappear, press the activator firmly until the device "snaps" and the activator is flush with the body of the SNAP device. Activate (snap) the device when the edge of the circle nearest the sample begins to turn from dark blue to white. Do not let the circle completely disappear.
