4-6 Test Procedure and Results
When the analyzer reaches operating temperature, it displays the
main analysis screen.
Note: Rotors can be used directly from the refrigerator.
(Prolonged time at room temperature can cause sup-
pression of chemistries and rotor cancellations.) Do
not expose rotors — in or out of pouches — to tem-
peratures higher than 32 ºC (90 ºF).
2. Inspect the unopened foil pouch for tears and punctures. Do not use a rotor from a dam-
aged pouch.
3. Collect the sample. See “Collecting Samples” on page 4-2 for instructions.
4. Tear open the rotor pouch at the notch on the edge of the package.
Note: A rotor must be used within 20 minutes of opening the pouch. Do not
refrigerate a rotor after opening the pouch.
5. Remove the reagent rotor from the pouch by holding the edges of the rotor. This elimi-
nates the possibility of fingerprints on the optical surfaces of the rotor.
CAUTION: Inspect the rotor for any damage before use.
6. Use a transfer device to dispense ~100 PL of sample into the sample port.
Note: Make sure whole blood samples are homogeneous before adding the
sample to the reagent rotor. Gently invert the collection tube several
times before filling the transfer device. Do not shake the collection
tube; shaking can cause hemolysis.
a. Place the transfer device in the sample port (see “Collecting Samples” on page 4-2)
and tilt the device until it is perpendicular to the rotor surface (device should touch
the sample port).
b. Fill the sample chamber by transferring the sample slowly and smoothly.
CAUTION: Do not apply excess blood to the sample port. Excess blood may contaminate
the analyzer.
