Intended Use
PATHFAST® hs-cTnl-II is an in vitro diagnostic test for the quantitative measurement of cardiac Troponin I (cTnl) in heparinized or EDTA whole blood and plasma. Measurements of cardiac Troponin I are used as an aid in the diagnosis of acute myocardial infarction (AMI). PATHFAST® hs-cTnI-II is for use in clinical laboratory or point of care (POC) settings.
Device Description
The PATHFAST® hs-cTnI-II test is a chemiluminescent enzyme immunoassay performed on the PATHFAST® instrument. Patient samples, whole blood or plasma, are dispensed by the operator into the designated area on the reagent cartridge. The instrument combines the patient sample, the antibody coated magnetic particles, and the alkaline phosphatase conjugate and incubates the mixture for 5 minutes at 37℃. During this incubation, the analyte in the patient sample binds to the antibody on the coated particles, and the alkaline phosphatase conjugate binds to the analyteantibody coated-particle. After the incubation, the instrument performs Bound/Free (B/F) separation using Magtration® technology to remove any excess unbound reagents. The chemiluminescent substrate is then added. The substrate is catalyzed by the bound alkaline phosphatase, which results in emission of photons. The photo-multiplier tube in the PATHFAST® instrument detects the photons that are emitted during the reaction. The chemiluminescent count is converted to analyte concentration values by the instrument based on the master calibration curve for the reagent lot. The PATHFAST® hs-cTnI-II test is supplied in reagent kits. Each kit contains sufficient materials for 60 determinations. The calibrator materials are included with the reagent kit and are also available separately. Calibration kits and diluent kits are also provided separately.

No
The description details a standard chemiluminescent immunoassay process and instrument operation, with no mention of AI or ML for data analysis, interpretation, or decision-making. The conversion of chemiluminescent count to concentration is based on a master calibration curve, which is a traditional method.

No.
This device is an in vitro diagnostic (IVD) test used to measure cardiac Troponin I (cTnI) for diagnostic purposes, not to provide therapy or treatment.

Yes

The "Intended Use / Indications for Use" section explicitly states, "PATHFAST® hs-cTnl-II is an in vitro diagnostic test for the quantitative measurement of cardiac Troponin I (cTnl)...Measurements of cardiac Troponin I are used as an aid in the diagnosis of acute myocardial infarction (AMI)." This clearly indicates its purpose is for diagnosis.

No

The device is an in vitro diagnostic test that is performed on a specific instrument (PATHFAST® instrument) and involves physical reagents and samples (whole blood, plasma, magnetic particles, alkaline phosphatase conjugate, chemiluminescent substrate). This clearly indicates a hardware component is essential to the device's function, making it not software-only.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The "Intended Use / Indications for Use" section explicitly states that the PATHFAST® hs-cTnl-II is an "in vitro diagnostic test".
  • Purpose: It is designed for the quantitative measurement of cardiac Troponin I (cTnl) in biological samples (whole blood and plasma) to aid in the diagnosis of acute myocardial infarction (AMI). This is a classic example of an in vitro diagnostic test, as it analyzes samples taken from the body to provide information about a person's health status.
  • Setting: It is intended for use in "clinical laboratory or point of care (POC) settings," which are typical environments for IVD use.

Precision, reproducibility, point of care precision reproducibility studies, high dose hook, traceability, stability, expected values, analytical specificity, assay cut-off, comparison studies, matrix studies, clinical sensitivity, clinical specificity, clinical cut-off and reference ranges are reported in K100130 PATHFAST® cTnI-II IFU.

Linearity/Assay Reportable Range:
Linearity studies were conducted on EDTA and lithium heparin whole blood and plasma samples. For the PATHFAST® hs-cTnI-II, the measurement procedure shows linearity for the interval from 4.1 to 50.000 ng/L, with deviations from linearity within +10%.

EDTA whole blood and plasma samples, and lithium heparin whole blood and plasma samples with low and high values were diluted to produce up to 12 dilution levels per each unique series with values ranging from 1 to 64,500 ng/L. Three-dilution series of each sample matrix were tested across three different lots of reagents. Each level was tested in replicates of three. The acceptable coefficient of variation for the replicates was set at

Intended use:

PATHFAST® hs-cTnl-II is an in vitro diagnostic test for the quantitative measurement of cardiac Troponin I ( c Tnl) in heparinized or EDTA whole blood and plasma. Measurements of cardiac Troponin I are used as an aid in the diagnosis of acute myocardial infarction (AMI). PATHFAST® hs-cTnl-II is for use in clinical laboratory or point of care (POC) settings.

The indications for use are identical to the predicate assay. The PATHFAST® hs-cTnl-II modified the reporting units from ng/mL to the conventional ng/L and extended the reportable range from 4.1 ng/L to 50,000 ng/L. The modification of the units and reportable range of the device does not affect the diagnostic or clinical utility of the device or the safety and effectiveness of the device when used as labeled.
