  • Page 8: Installation Guidelines

    Installation Guidelines Step 1: Unpack the VetScan VS2 Analyzer and Accessories Immediately upon receipt, place the box of reagent rotors in a refrigerator (2–8 ºC or 36–46 ºF). Remove the analyzer from its box and place it on a sta- ble, level surface.

  • Page 9: Step 3: Install Printer Paper Roll

    Step 3: Install Printer Paper Roll Open the printer cover. If the printer contains a roll of printer paper, remove it from the printer. Remove the wrapper from the new paper roll, then unroll several inches of paper. Put the roll into the printer so that paper unrolls from the bottom of the roll and out towards the front of the analyzer, as shown at right.

    See Section 5‚ “Selecting Units” for instructions on chang- ing to SI units such as mmol/L. The VetScan VS2 is now ready to run samples. See Section 4‚ “Test Procedure and Results” for instructions. If You Have Problems If any of the following occurs, see Section 8‚...

  • Page 11: Guidelines For Obtaining And Using Samples

    Use only powder-free gloves, to keep powder off of analyzer optics. Use only reagent rotors that have not expired, as noted on the pouch and box. The VetScan VS2 Analyzer automatically rejects expired rotors. Do not remove the rotor from the refrigerator until you are ready to run the analy- sis.
  • Page 12 Guidelines for Obtaining Samples Serum samples: Use no-additive evacuated specimen collection tubes or serum separator tubes. Whole blood or plasma samples: Use only lithium heparin evacuated specimen collection tubes. Obtain a sample of approximately 100 µL. When collecting the sample in lithium heparin collection tubes, fill the tube at least half-way to maintain the proper ratio of sample to anticoagulant.
  • Page 13 Test Tube Order To prevent contamination, always fill test tubes in this order: Red top: No anticoagulant. Note: Use the red top test tube only if necessary. If the red top tube is not needed, fill the green top tube first. But when needed, the red top tube must be filled before any other.

  • Page 14: Step 3: Add Sample To The Rotor

    Syringe pre-wetted with lithium heparin. Make sure the heparin concentration is 15 units per mL of blood. Expel excess heparin by moving the plunger back and forth several times, until only a fine coating is left inside the syringe barrel. This is important for preventing excess sample dilution, which will alter final sample results and can cause errors.
  • Page 15 Using a Fixed 100 µL Volume Pipette Firmly attach a new tip to the end of the pipette. Do not touch the tip, or a false elevation of amylase can result. With your index finger or thumb, push the pipette plunger to the stop position, and hold it there for sample pickup.

  • Page 16: Step 4: Analyze The Sample

    Using a Lithium Heparinized Syringe The sample can be dispensed directly into the rotor from a heparinized syringe. Gently invert the syringe three or four times to mix well. Remove the needle from the syringe before dispensing the sample, to minimize hemolysis. See “Sample Delivery Volume”...

  • Page 19: Frequently Asked Questions

    Can the analyzer detect a flawed or defective rotor? Yes. The VS2’s extensive Intelligent Quality Control (iQC) detects any flaw or potential anomaly in the rotor. Abaxis also provides a Performance Guarantee covering manufac- ture-defective rotors. (This does not include cancellations or assay suppressions due to improper rotor storage, operator error, or inadequate sample integrity.)

  • Page 20: Analyzer Setup

    Does the VS2 need surge protection or an uninterruptable power supply? Abaxis recommends plugging the VS2 into a surge protector designed for use with a com- puter. Abaxis also recommends using an uninterruptable power supply (UPS) in areas prone to electrical surges or power outages.

  • Page 21: Samples

    Samples What types of samples can I run on the VS2? Whole blood, serum, or plasma. Is precision pipetting required? No. Adding approximately 100–120 l of sample is sufficient. (Make sure not to overfill the chamber, or internal spills can result.) The VS2’s on-board microfluidics handle the rest.

  • Page 22: Testing And Results

    Endogenous substances such as hemolysis, lipemia, and icterus affect all blood chemis- tries, regardless of the type, size, or cost of the analysis instrument. The VetScan VS2 is the only point-of-care analyzer that assesses and suppresses hemoly- sis, lipemia, and icterus by determining assay-by-assay the level at which these substances could affect the reliability of the results, and bringing this to the user’s attention.
  • Page 23 Can I back up the results on my VS2? No, but you can print out reference ranges and results, or transfer them for storage in your lab management software. Can patients other than equine, large animal, or avian use the Equine, Large Ani- mal, and Avian profiles? No.

Dilution of Sample 1:1 with Saline (Use serum or heparinized plasma) Combine one part (100 L) serum or heparinized plasma with one part (100 L) normal saline (0.9%) (do not use distilled water) into a clean, red top tube and gently mix. Use the diluted sample for testing.

    The reagent rotor contains a diluent, and test-specific reagent beads. The operator then places the rotor in the VetScan VS2 Chemistry Analyzer and enters the appropriate identification numbers. The VS2 Analyzer automatically performs the remainder of the testing protocol.

  • Page 104: Principles Of Operation

    Principles of Operation Chemical reactions occur between reagent beads, the diluent contained in the reagent rotor, and the added sample. These reactions produce chromophores that are measured photometrically by the VS2. The microprocessor then calculates the concentrations of the analytes. The measurement optics include a stroboscopic xenon lamp, a wavelength selection system, and a multiple-wavelength detector.

    The equation for calculating absorbance is this: (I λ1RC - I λ1 ) / (I λ2RC - I λ2 A = -log (I λ1OC - I λ1 ) / (I λ2OC - I λ2 where: = Absorbance at wavelength 1, referenced to wavelength 2 = Intensity of light transmitted through the reaction cuvette at wavelength 1 = Intensity of light transmitted through the reaction cuvette at wavelength 2 = Intensity of light transmitted through the dark cuvette at wavelength 1...

  • Page 106: Endpoint Reactions

    Endpoint Reactions Reagents, samples, and chromophores all absorb light in endpoint reactions. Light absorption by the samples must be subtracted so that the analyte concentration can be isolated. The absorbance of the sample is measured in a sample blank cuvette. Some chemistries employ a generic sample blank and others (such as total bilirubin) use a dedicated sample blank.
