PERFORMANCE CHARACTERISTICS

Pneumatic Supplies (Internally Regulated)
Pressure = 60 psi (pounds per square inch)
Vacuum = 22 in. Hg (inches of mercury) minimum at sea level
Calibration Stability
Variation with temperature: If ambient room temperature changes by less than 5.5ºC (10ºF)
from the calibrating temperature, and the temperature is within the temperature
specifications, then the LH 700 Series does not require calibration.
LH Workstation Storage
Patient results,
r
up to 20,000 with numeric, graphic and list mode data.
Known Interfering Substances
CBC
IMPORTANT
The operating temperature influences the rate of kinetic reactions. The online help states that
the LH 700 Series System should be recalibrated whenever the ambient temperature changes by 10 degress
Fahrenheit. If you have to recalibrate due to a large change in laboratory ambient temperature, you should
re-evaluate the differential flagging sensitivity settings for your typical patient population.
All
Misleading results can occur if the specimen is not properly collected, stored or
transported. Beckman Coulter recommends that you follow NCCLS or equivalent
procedures to ensure proper specimen collection, storage and transport. Always
follow manufacturer’s recommendations when using microcollection devices for
capillary specimen collection.
All
Misleading results can occur if specimens contain clots. Always use good
laboratory practices for inspecting specimens for clots and verifying results.
All
Misleading results can occur if the specimen is not properly mixed. Always use
good laboratory practices to ensure specimens are appropriately mixed. Do not
bypass or circumvent the automated mixing process used on the LH 700 Series.
WBC
NRBCs, giant platelets, platelet clumps, malarial parasites, precipitated elevated
proteins, cryoglobulin, microlymphoblasts, very small lymphocytes, fragmented
white cells, agglutinated white cells, lyse resistant red cells, unlysed particles >
35 fL in size.
Elevated WBC counts may have a carryover effect on subsequent leukopenic
specimens, within the limits specified in the Carryover Section.
IMPORTANT
If a sample is run that has a WBC greater than 600 x 10
3
/µL and
a prominent Lymphocyte population, the system will flag the WBC result with
an "R" flag. The "R" Flag without Cellular Interference message indicates the
need to perform a manual differential and rerun a diluted sample of the
specimen.
