    “Good Laboratory Practice”. The CA620-CellGuard is intended to be used especially in blood banks as pre do- nor screening as well as a quality control tool for PLT concentrates in a blood bank production facility.

  • Page 10: General Warnings

    Safety Instruction If, under these prescribed conditions of operation and maintenance, an aberrant or abnormal result occurs, as defined by the laboratory protocol, laboratory per- sonnel should first make certain that the system is performing and is being oper- ated in accordance with the Product Labelling. The laboratory protocol should than be followed to advise the clinician in case a result appears to have deviated from the norms established by the laboratory.

  • Page 11: Emergency Procedure

    Safety Instruction • When handling reagents. - If a reagent happens to enter your eye, wash it off immediately using plenty of water and take action to seek medical treatment at once. - If it happens to adhere to the hand or skin of other body parts, wash it off using plenty of water.

    2 Specifications General The operator works with a menu from which the desired program is chosen, e.g. discriminator settings, calibration, cleaning etc. Two external reagent reservoirs are used: • Isotonic diluent. • Hemolyzing reagent. Whenever one of these external reservoirs is empty, this is indicated on the dis- play.

  • Page 18: Limitations

    Specifications Limitations Verification of any abnormal test result (including flagged results or results out- side of the normal range) should be performed using reference methods or other standard laboratory procedures for the conclusive verification of results. The sec- tion below list known limitations of automated blood cell counters in general as well as specific issues for cell counters using the impedance technology.
  • Page 19 HGB (hemoglobin) Turbidity of the blood sample due to any number of physiological and/or thera- peutic factors may produce falsely elevated HGB results. The CA620/530 how- ever is compensated for this effect with high WBC counts up to WBC approx. 60 10e3/µl.
  • Page 20 Specifications RDW (Red Cell Distribution Width) The red cell distribution width is a function of the RBC count and derived from the RBC histogram. In most cases, any error introduced in the MCV may also cause the RDW to be erroneous. Especially blood transfusions may raise the RDW significantly due to the presence of bi-modal populations.
  • Page 21 Specifications MPV (Mean Platelet Volume) Giant platelets Large platelets counted as RBCs will fall outside the PLT range and therefore lower the MPV. Small erythrocytes Very small RBCs might fall into the PLT region and might be counted as PLTs and therefore influence the MPV parameter.

  • Page 22: Differences Between Ca620 And Ca530

    The CA620-CellGuard can be configured as a donor screening device or as a tool to determine the PLT concentrations in PLT bags. In case the instru- ment is used for donor screening, it is fully identical to a CA620 16 param- eter machine.

  • Page 23: Plt

    Specifications The menu numbering for the CA620, CA620-CellGuard and CA530 is identical. This user manual is therefore applicable for both type of instruments. The following table shows which parameters are available on the 9, 16 and 20 pa- rameter models:...

  • Page 25: Measuring Principles

    3 Measuring Principles RBC,WBC and PLT Concentration Detection Detection is accomplished using the electronic impedance principle and occurs in the orifice of the transducer. The blood is diluted to 1:400 (WBC & HGB) and 1:40000 (RBC & PLT) through a precise shear valve system. The shear valve (sampling valve, marked in the figure below) “cuts”...
  • Page 26 Measuring Principles electrical current electrodes cells Flow direction 1018.tif A=Aperture The PLT, RBC and WBC parameters are measured on a precise aliquot of the sample. The amount of sample measured is determined by the volume of a pre- cise glass column; called a metering tube. Two optical detectors are used to start and stop detection.

  • Page 27: Sizing Rbc, Wbc And Plt

    Measuring Principles All cells smaller than the upper PLT discriminator level will not be recognised as red cells. In case the user has selected a “floating” discriminator; RBC cells are counted from the set-point of this variable discriminator, which varies from sam- ple to sample between the volume limits set by the user.

  • Page 28: Counting Time Rbc & Wbc

    Measuring Principles Counting Time RBC & WBC The microprocessor system checks the counting time for the RBC and PLT counting process. The counting time is defined as being the time needed for the sample to be drawn from the start- to the stop detector in the metering unit. See RBC,WBC and PLT Concentration Detection on page 25.
  • Page 29 Measuring Principles 4 hours old fixed discriminators fresh” blood LYMF GRAN Volume (fl) 1020.tif To overcome the above mentioned problem, the instrument utilizes a so-called mathematical differential, where the curves are analyzed within the software and 3 separate curves are built through a curve fitting method. Hence, the software of the instrument is building an artificial matching distribu- tion around the main populations.

  • Page 30: Mcv (Mean Cell Volume Rbcs)

    Measuring Principles MCV (Mean Cell Volume RBCs) The MCV parameter is derived from the RBC distribution curve. As the distribu- tion curve has a maximum volume range of 250fl, the maximum channel also contains clumps of cells that are larger than this volume. Therefore this channel is excluded from the MCV calculation.

  • Page 31: Mpv (Mean Platelet Volume)

    RBC-PLT population. CA620-CellGuard PLT (Platelets) In case the CA620-CellGuard is programmed and used for PLT concentrates, the reproducibility is better than the stated CV figures above, as CV is a concentra- tion dependent parameter.

  • Page 32: Lpcr (Large Platelets)

    Measuring Principles 3.12 LPCR (Large Platelets) The LPCR (Large Platelets Concentration Ratio) parameter is calculated from the PLT distribution curve. Platelets that are larger than 12 fl up to the (floating) dis- criminator are expressed in % of the total PLT count. The LPCR parameter is only valid if the MPV value is not zero.

    Parameter Flags TU (Time-out Upper Detector) The error flag TU might be displayed on the following parameters: RBC, PLT and/or WBC. This error is related to the counting time. It means that the count- ing time is outside the limits and displayed as “HI” or “LO”. Note: The instrument performs an auto-clean of the orifice after a TU is displayed;...

  • Page 35: Fd (Floating Discriminator)

    Parameter Flags FD (Floating Discriminator) If the discriminator, between the upper volume of PLT and the lowest volume of RBC, has been set as floating (see set-up menu) the instrument tries to find a min- imum on the PLT / RBC curve. At this point, the floating discriminator will be set.

  • Page 36: Se (Statistical Error Hgb)

    4.13 RP (Red Cells Present) This flag is only displayed in case the CA620-CellGuard is used for PLT concen- trates. If the concentration of Red Blood Cells is > 0.3 in the PLT concentrate, both RBC and PLT are flagged with 'RP' to indicate that Red Cells are present and that the PLT value may not be correct.

  • Page 37: Ec (Expired Control)

    Parameter Flags 4.14 EC (Expired control) This warning is displayed in case a Boule certified blood control is entered and the current date is more recent than the expiry date of the control. Note: The control must have been defined previously with the bar-code reader in menu 7.4.1.

  • Page 93: Printer And Serial Output

    12 Printer and Serial Output Following is a description of the printer and data outputs of the CA620/530 and the CA620-CellGuard analyzers. The system has 2 outputs. One is of a Centron- ics format and the second a serial output with RS232 specifications. A standard Centronics cable should be used and connected to a proper printer.

  • Page 94: The Serial Output Format

    Preferably, use a computer in terminal mode connected to the instrument to vi- sualize the data and to get familiar with the format. Please put your browser at: http://www.medonic.se/user-support/CA620-530/dataformat. And download the available information, such as: Data format description Programming notes...

  • Page 100: Hgb Value Flagged With Hi

    Trouble Shooting The lamp voltage is usually ca. 4.5 Volts and the photometer output ca. 3.5 volts. These values are not critical as long as the photometer output voltage is between 3.2 and 3.8 volts. If the photometer output voltage is lower than 2.5 volt, a “LO” indication will follow on the HGB parameter value.
