About SNAP tests
Note: The following questions do not apply to SNAP ST tests.
It’s easy. Watch the training videos.
SNAP tests take less than 10 minutes to run.
Please refer to your package insert for test-specific storage requirements. Refrigerate SNAP NBL Tests at 0–7°C (32–45°F). Refrigerate all other non-ST tests at 2–8°C (36–46°F). Tests can be kept at room temperature, 18–29°C (64–84°F), during the day of use. Remove only the number of tests to be used for the day.
No, you do not need to warm the tests prior to use; you can run the SNAP tests directly out of the refrigerator. Do not open the foil pouch until you're ready to run the test.
Before you test:
- Verify that the SNAP device has coloured spots in the results window and activation circle.
- Make sure the pellet is moving freely in the bottom of the sample tube.
- Be sure your heater block has been preheated to a temperature within the 45°C ±5°C range.
SNAP tests must be run at 45°C ±5°C (104–122°F). The SNAP portable heater blocks have internal thermostats optimized within the range of 40–50°C. Allow 10–15 minutes for the portable heater to reach operating temperature. If you do not see any color in the block’s temperature strip, do not attempt to run the test. Contact IDEXX Technical Services if you have any questions about heater performance. Call 00800-329-43399, Monday–Friday, 8:00 a.m. to 5:00 p.m. ET; or contact us.
Yes, the SNAP test must remain on the heater block at 45°C ±5°C for the duration of the test—during the incubation time, the activation time and the color-development time.
Activation time is critical. After the initial incubation, 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. Always 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.
SNAP technical top - When to "SNAP"
The number of SNAP tests you can run at one time depends on the type of heater block you have. With the preset portable models that IDEXX offers, you can accommodate two SNAP devices at one time.
If you're running multiple samples, set up all samples and SNAP devices on the heater, then set a timer for the incubation period. After incubation, individually pour the samples onto the sample well of each device. Watch the devices carefully as each sample may flow at a different rate. Activate each device as the individual activation circles begin to disappear. Snap the devices completely, and set a timer for the appropriate colour-development time (it varies by test) after the last device has been activated. When the time period is complete, you can read the results.
Yes, the SNAPshot® DSR Reader is approved and available from IDEXX.
