Glossary of Terms
Bidirectional
communication means that there is two-way communication from the Interrliner to the HOST
(sample requests and results) and from the HOST to the Interrliner (confirmation or denial of sample
requests).
Citrate mode
is used for
pre-diluted samples collected in tubes with sodium citrate anticoagulant-diluent.
The samples are
not diluted on the Interrliner during aspiration.
The concentration of sodium citrate within the diluent solution in the tube should be 3.2%. This is not to be
confused with the required dilution rate of blood and diluent.
For example, in a citrate tube with a total draw volume of 1.6 ml (= 5 volumes), the amount of pre-filled
diluent must be 0.32 ml (= 1 volume). If this information is not provided by the tube manufacturer, it should
be checked by the customer.
EDTA mode
is used for
undiluted samples collected in tubes with EDTA anticoagulant. The samples are
automatically diluted on the Interrliner during aspiration.
The usual amount of EDTA in sample tubes is 1.8 mg per 1 ml blood. 1 ml of blood weighs ca. 1060 mg and
the concentration of EDTA is therefore 0.17% and well within the requirements for the EDTA mode on this
instrument.
ESR
is short for
Erythrocyte Sedimentation Rate.
It is the amount of sedimentation (setting) of
erythrocytes (red blood cells) in a blood column during a specified time.
Hazy
: A sedimentation is reported to be "
hazy
", when the boundary between blood plasma and
erythrocytes can not be defined clearly.
HOST
: In this manual, the term
HOST
is used to indicate the computer system and associated software
(LIMS) that provides the sample management for the laboratory.
IVD
is short for
In Vitro Diagnostic.
This kind of diagnostic is performed on biological samples in a test
tube, or more generally in a controlled environment outside a living organism.
In vitro means in glass in
Latin.
MRN
is short for
Master Registration Number
. It is used as an identification number for any manual for
Mechatronics products.
MSDS
is short for
Material Safety Data Sheet
. In this type of MSDS all kind of important data can be
found on reagents.
Temperature correction
: The sedimentation of blood cells is a temperature dependent process. To
achieve comparable results,
temperature correction
should always be used. The ESR results are then
corrected to the value they would have been at the
standard temperature of 18.3°C.
Unidirectional
communication means that there is only one-way communication from the Interrliner to the
HOST. Only sample results and result related messages are send.
WI
is short for
Work Instruction
and is used with an index number for a range of work instructions.
