1. Glossary of Terms

Capillary Blood: Blood from the smallest
blood vessels of the body - usually obtained
from a fingerstick.
Data Port: The port located on the top
left side of the monitor for connecting to a
computer.
Electrodes: The part of the test strip
that generates an electrical current that is
impeded by the blood sample once it mixes
with coagulation reagents.
Fingerstick: A small puncture to the finger.
Hanging Drop: A drop of blood that forms
after a fingerstick that is large enough to hang
from the fingertip. Collecting a
hanging drop helps to ensure that an
adequate sample (at least 15μL) is being
applied.
(listed alphabetically)
Hematocrit: The percentage of your blood
that is red blood cells.
Heparin: A medication taken by injection
that is used to prevent the formation of blood
clots by inactivating thrombin.
Hemoglobin: The oxygen-carrying
pigment and main protein in red blood cells.
Hemolysis: The destruction of red blood cells
leading to the release of hemoglobin from
within the red blood cells into blood plasma.
Leaving alcohol on the fingertip puncture site
prior to a fingerstick may lead to hemolysis.
Hemolysis should be avoided because it may
interfere with the results of the Prothrombin
Time (PT) test.
Impedance: Resistance of the blood
sample as it coagulates to the electrical
current produced by the electrodes. The
INRatio2 PT monitor measures the change in
impedance in the blood sample to
calculate Prothrombin Time (PT).
International Normalized Ratio (INR):
Standardized system of reporting
Prothrombin Time (PT) that takes into
account the different sensitivity of
thromboplastins (reagents) used in various
methods. INR results are comparable across
PT measurement systems.
In Vitro Diagnostic: A diagnostic test done
outside the body.
Interstitial fluid: Fluid between cells in
the body.
Lancet: A pointed device used to make a
small incision or fingerstick to collect the
small drop of blood used in performing a
Prothrombin Time (PT) test.
Oral Anticoagulant: Any oral medication
(e.g., Coumadin®) used to prevent the
formation of blood clots.
Plasma: The liquid part of blood.
Power Jack: The power port located on the
top right hand side of the monitor for use
with the INRatio2 power supply.
Prothrombin Time (PT): Any test that
measures the clotting time of plasma. The
INRatio2 PT monitor measures PT time using
a capillary blood sample.
Quality Control (QC): The testing done to
show that the monitor is working properly
and giving dependable results.
Reagent: A substance in the test strip that
mixes with the blood sample
Sample Light: The green light on the
monitor test strip guide that is directly under
the sample well of an inserted test strip. This
light helps users identify where to place the
blood sample on a test strip.
Sample Well: The round hole (target) on
the single-use test strip where the blood
sample is applied.
Strip Code: Code entered and used by the
INRatio2 PT monitor that corresponds to the
code identified on the test strip pouch/
container. This strip code must match each
new lot of test strips for your results to be
accurate.
Test Strip: A single-use test strip used to
perform the Prothrombin Time (PT) test with
the PT Monitor.
Thromboplastins: A substance used by
blood platelets and combined with calcium
that converts prothrombin (protein) into
thrombin (enzyme) as part of the clotting
cascade.
Warfarin: An oral medication used to
prevent the formation of blood clots.
