How can I get additional support/information?
We have provided the most frequently asked questions to help you get
started. When you receive your order, you will also receive detailed
printed instructions that fully outline how to use your SNAP Heater
Block and your SNAP tests. Anytime you have questions, you can call
IDEXX Technical Services at 00-800-329-43399, Monday

or e-mail Technical Services.
How should I store my SNAP tests?
Refrigerate all SNAP materials at 0°–7°C. Tests can be
kept at room temperature, 18°–29°C, during the day of
use. Remove only the number of tests to be used for the day.
How long does the SNAP test take?
The SNAP rapid-screening method produces results in less than ten
minutes.
What is the proper heater block temperature?
The SNAP test kits must be run at 45°C ±5°C. The SNAP
Portable Heater Blocks have internal thermostats optimised 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
colour in the 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 through Friday, 8:00 a.m. to 4:30 p.m., fax 00800-43399-329
or send us an e-mail.
How critical is the activation time of the
SNAP test?
Activation time is very critical. After the initial five-minute
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. (When the edge of the circle nearest
the sample begins to turn from dark blue to white, activation should
occur. Do not let the circle completely disappear.)

Does the SNAP device need to remain on the
heater block throughout the entire test?
Yes, the SNAP device must remain on the heater block at 45°C
±5°C for the duration of the test—during the
five-minute incubation time, the activation time and the four-minute
colour-development time.
Can I test more than one sample at a time?
The number of SNAP tests you can run at one time depends on the type
of heater block you have. IDEXX offers two models, one holds two SNAP
devices and the other holds four SNAP devices.
If you're running multiple samples, set up all samples and SNAP
devices on the heater, then set a timer for five minutes. After the
five-minute incubation, individually pour the samples into 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 four-minute colour-development time after
the last device has been activated. After four minutes, you can read
the results.
Do the SNAP tests need to be brought to room
temperature before testing?
No, you do not need to warm the kits 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 prespots in the results window
and activation circle.
- Make sure the pellet is moving freely in the bottom of the sample
tube.
- Be sure the heater block has been preheated to a temperature
within the 45°C ±5°C range.
Does IDEXX have a reader for the SNAP tests?
Yes, the SNAPshot Reader is available. More information

Will the SNAPshot Reader provide the same
results as the original SNAP Image Reader?

printer can be attached to provide hard-copy results. You can purchase
a printer through IDEXX (part #98-09415-00). Printers come fully
equipped and ready to use with the SNAPshot Reader.
