Intended Use
The Multiplate 5.0 aggregometer is intended for in vitro use to measure platelet aggregation in response to Arachidonic acid or ADP in citrated whole blood samples for the qualitative assessment of platelet function. The ADPtest reagent is a lyophilized preparation of adenosine-5-diphosphate for in vitro diagnostic use to measure platelet aggregation for the qualitative assessment of platelet function. For professional laboratory use only. The ASPItest reagent is a lyophilized preparation of arachidonic acid (AA) for in vitro diagnostic use to measure platelet aggregation for the qualitative assessment of platelet function. For professional laboratory use only. For use as an assayed quality control verification of the resistance measure of impedance aggregometry.
Device Description
The Multiplate® 5.0 measures platelet function in whole blood samples using electrical impedance. The Multiplate technology employs multiple electrodes in a disposable test cell. Four electrodes form two independent sensor units allowing for two measurements on the same sample. Five independent channels of the instrument allow for testing of multiple reagents or samples simultaneously. The instrument provides a five channel aggregometer and an integrated computer system with associated software and is connected to a computer screen, keyboard, mouse, and an electronic pipette. The software is used for data collection and is not used for diagnosis or treatment. Currently, two test reagents (ADP and Arachidonic acid) are available that activate platelets through specific platelet membrane receptor/signal transduction pathways in order to measure platelet function or alterations in function.

Description of the test set, sample size, data source, and annotation protocol

Multi-center studies were run to compare the performance of the Multiplate 5.0 to the predicate device. Samples from 171 patients suspected of decreased platelet function were drawn and measured in duplicate.
Clinical sensitivity and specificity were calculated against Platelet Function Status. Platelet Function Status of each sample was based upon a physician panel's review of each patient's clinical history. Samples from 91 patients suspected of decreased platelet function which were drawn and measured in duplicate.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Two multi-center studies were performed.
The first study compared the performance of the Multiplate 5.0 to the predicate device.
Sample size: 171 patients.
Key results: The positive and negative percent agreements (PPA and NPA) of the Multiplate to the Chrono-log were calculated.
For Arachidonic acid: PPA = 100% [96%, 100% CI], NPA = 65% [54%, 75% CI].
For ADP: PPA = 93% [81%, 97% CI], NPA = 54% [45%, 62% CI].

The second study analyzed sensitivity and specificity.
Sample size: 91 patients.
Key results: Clinical sensitivity and specificity were calculated against Platelet Function Status, which was based on a physician panel's review of each patient's clinical history.
For ASPItest (Arachidonic acid): Sensitivity = 93% [85%, 97% CI], Specificity = 67% [44%, 84% CI].
For ADPtest: Sensitivity = 59% [46%, 70% CI], Specificity = 80% [63%, 90% CI].

Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)

Arachidonic acid (against predicate): Positive Percent Agreement (PPA) = 100%, Negative Percent Agreement (NPA) = 65%

The Multiplate 5.0 has been found to be substantially equivalent to the previously cleared Chronolog Model 700 Whole Blood Lumi-Aggregometer (K050265).

1. Device Description

The Multiplate® 5.0 measures platelet function in whole blood samples using electrical impedance. The Multiplate technology employs multiple electrodes in a disposable test cell. Four electrodes form two independent sensor units allowing for two measurements on the same sample. Five independent channels of the instrument allow for testing of multiple reagents or samples simultaneously.

The instrument provides a five channel aggregometer and an integrated computer system with associated software and is connected to a computer screen, keyboard, mouse, and an electronic pipette. The software is used for data collection and is not used for diagnosis or treatment.

Currently, two test reagents (ADP and Arachidonic acid) are available that activate platelets through specific platelet membrane receptor/signal transduction pathways in order to measure platelet function or alterations in function.

2. Intended Use

The Multiplate 5.0 aggregometer is intended for in vitro use to measure platelet aggregation in response to Arachidonic acid or ADP in citrated whole blood samples for the qualitative assessment of platelet function.

The ADPtest reagent is a lyophilized preparation of adenosine-5-diphosphate for in vitro diagnostic use to measure platelet aggregation for the qualitative assessment of platelet function. For professional laboratory use only.

The ASPItest reagent is a lyophilized preparation of arachidonic acid (AA) for in vitro diagnostic use to measure platelet aggregation for the qualitative assessment of platelet function. For professional laboratory use only.

3. Technical Description

The Multiplate uses the same scientific principles of detection as the predicate Chrono-log Model 700 with the exception that it does not include the capability of platelet function measurement based on luminescence or turbidimetric light transmission measurement.

1

Both devices employ the same principle of measurement: electrical impedance, first cited in 1980 by Cardinal and Flower, (J Pharmacol Methods.1980;3:135-158). An electrical current passes through individual sets of electrodes. When the electrodes come into contact with a whole blood sample platelets bind to and cover the electrodes in a small monolayer. As the platelets become activated after exposure to a specific platelet agonist, the platelets strongly adhere to the electrodes and begin to aggregate. An increase in the number of platelets adhering to the electrodes increases the resistance (impedance) between the pair of electrodes.

Potential improvements of the Multiplate system are the introduction of dual sensor technology that records two measurements in each test cell based on two individual pairs of electrodes. The mean value is then reported. The final measurement is reported in Units (U) which represents the area under the curve that is generated by graphing the change in resistance.

4. Performance

...

Multi-center studies were run to compare the performance of the Multiplate 5.0 to the predicate device. Samples from 171 patients suspected of decreased platelet function were drawn and measured in duplicate.

The positive and negative percent agreements of the Multiplate to the Chrono-log were calculated. The results were considered positive if the test value was below the reference range for the specific device. The results were considered negative if they fell within the reference range for the specific device. Using this data, the positive percent agreements (PPA) and negative percent agreements (NPA) were calculated.
