2.1 Intended use
The PFA-100 Platelet Function Analyzer and Dade PFA-100 Reagents are
in vitro diagnostic devices intended to aid in the detection of platelet
dysfunction in citrated human whole blood.
The PFA-100
®
System is an instrument and test cartridge system in which
the process of platelet adhesion and aggregation following a vascular injury
is simulated in vitro. Platelet dysfunction detected by the PFA-100 System
may be acquired, inherited, or induced by platelet inhibiting agents.
The PFA-100 System is for in-vitro diagnostics only.
The instrument’s functions are:
• Moving the carousel (containing PFA test cartridges with samples) into
the instrument
• Reading the test code
• Dispensing the trigger solution into each PFA test cartridge
• Incubating the samples
• Aspirating the sample through the aperture of the PFA test cartridge
• Measuring the blood flow rate through aperture at a constant vacuum
• Determining the closure time by detecting a flow rate, which is for three
seconds below 10% of the initial flow rate at the beginning of the test
• Calculating and analyzing the readings
• Printing the readings
One or two PFA test cartridges containing samples can be placed in the
instrument after:
• Loading the required PFA test cartridges
• Entering the test
Then the samples are processed fully automatically as far as the
analysis stage.
