4.1 Introduction to Testing
Note: Use only VetScan Reagent Rotors with the
VetScan VS2 Chemistry Analyzer.
The basic testing procedure is listed below. The remainder of this section
describes the details of collecting samples and preparing the reagent
rotor (Section 4.2), sample processing (Section 4.4), and interpreting
results (Section 4.6).
1. Store rotors in a refrigerator (2–8 ºC, 36–46 ºF). Rotors can be
used directly from the refrigerator without warming.
2. Collect the sample (lithium-heparinized whole blood, lithium-
heparinized plasma or serum).
3. Remove the reagent rotor from its pouch.
CAUTION: Inspect the rotor for any damage before use.
4. Dispense ~100 PL of sample into the
rotor through the sample port, as
shown at right.
A 100 PL sample forms a line
between the two arrows printed on
the rotor. If there are air bubbles in
the chamber, add more sample (not to exceed 120 PL). Expel air
or bubbles from the tip of the transfer device before adding more
sample.
