Drucker Diagnostics Paralens Advance - Manual (Page 22)

3.1.8 HDR Analysis Report*
The microprocessor, via the cartridge memory
bank, contains an extensive database of medical
diagnoses against which each nine-parameter test
result is analyzed. The test printout will include a
hematology diagnostic reminder or HDR report on
general and specific clinical aspects relating to any
abnormal values. Wintrobe’s Clinical Hematology,
8th edition,
1 is referenced throughout the printed
HDR report. See the Caution note opposite on
proper utilization of HDR report.
Abbreviated (Short) or detailed (Long) analysis
reports can be obtained. See Section 2.4.4 on
programming HDR report printouts.
*Not provided in all cartridges.
3.2 AUTOREAD PLUS POWER PACK
The power pack supplies direct current (d.c.)
voltages to the Autoread Plus analyzer. The power
pack incorporates a conventional flyback switching
design with four individually regulated d.c. outputs,
as shown in Figure 3-13.
The Power switch on the analyzer controls and cuts
the +20V and +12.5V supplies, the ±16.5V supply
being switched off electronically by cutting the
12.5V supply to the logic circuits.
3.3 QBC CAPILLARY CENTRIFUGE
The QBC Capillary Centrifuge (Figure 3-14) is
a low-noise, high-speed instrument specifically
designed to meet the cell packing requirements of
the QBC test method.
Up to 20 blood tubes can be spun simultaneously.
Nominal speed is 12,000 rpm and relative centrifugal
force is approximately 14,387× g. Spin time is fixed
at 5 minutes. For a detailed description of the QBC
Capillary Centrifuge including setup and operating
instructions see the operator’s manual shipped with
the instrument.
Since the QBC test method depends on proper
cell layering of blood, the sample tubes must be
protected from excessive heat in the centrifuge rotor
compartment, which may adversely affect cell layer
formation. Accordingly, be sure to wait between
successive spins for the correct time specified in
the applicable QBC Capillary Centrifuge manual.
CAUTION
A clinical diagnosis is a conclusion based
on science and art that necessitates the full
integration of the results of a detailed medical
history, a careful physical examination and
appropriate laboratory testing, together with
the training, experience, and professional
judgment of the treating physician. The
statements derived by the HDR program are
suggestions based upon a limited examination
of only a part of a patient’s hematologic status.
HDR reminders have value only to a clinician
who is able to use them as part of the complete
diagnostic process.
