Intended Use
HemosIL D-Dimer is an automated latex enhanced immunoassay for the quantitative determination of D-Dimer in human citrated plasma on IL Coagulation Systems for use in conjunction with a clinical pretest probability (PTP) assessment model to exclude venous thromboembolism (VTE) in outpatients suspected of deep venous thrombosis (DVT) and pulmonary cmbolism (PE).
Device Description
The D-Dimer Latex Reagent is a suspension of polystyrenc latex particles of uniform size coated with a monoclonal antibody highly specific for the D-Dimer domain included in fibrin soluble derivatives. When a plasma containing D-Dimer is mixed with the Latex Reagent and the Reaction Buffer included in the D-Dimer kit, the coated latex particles agglutinate. The degree of agglutination is directly proportional to the concentration of D-Dimer in the sample and is determined by measuring the decrease of the transmitted light at 405 nm caused by the aggregates (turbidimetric immunoassay).
More Information

No
The device is a turbidimetric immunoassay and the summary does not mention any AI/ML components. The use of a clinical pretest probability model (Wells model) is mentioned, but this is a standard clinical assessment tool, not an AI/ML component of the device itself.

No
The device is an in vitro diagnostic (IVD) immunoassay designed for quantitative determination of D-Dimer, used to exclude venous thromboembolism (VTE) in conjunction with a clinical PTP assessment. It measures a biomarker and provides diagnostic information, but does not directly treat or prevent a disease.

Yes
The device is described as an "automated latex enhanced immunoassay for the quantitative determination of D-Dimer," used "in conjunction with a clinical pretest probability (PTP) assessment model to exclude venous thromboembolism (VTE) in outpatients suspected of deep venous thrombosis (DVT) and pulmonary embolism (PE)." This clearly indicates its use in diagnosing or ruling out a medical condition.

No

The device description clearly states it is a "suspension of polystyrene latex particles" and a "Latex Reagent," which are physical components, not software. It also describes a turbidimetric immunoassay process involving light measurement, indicating hardware is involved.

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

Here's why:

  • Intended Use: The intended use explicitly states it's for the "quantitative determination of D-Dimer in human citrated plasma". This involves testing a sample taken from the human body (plasma) in vitro (outside the body) to provide diagnostic information.
  • Device Description: The description details a "latex enhanced immunoassay" that measures the concentration of D-Dimer in a plasma sample. This is a common method used in IVD devices.
  • Performance Studies: The document describes a multi-center management study where the device was used to test patient samples and the results were compared to clinical outcomes (development of DVT or PE). This is typical of performance studies for IVD devices.
  • Key Metrics: The document provides key performance metrics like Sensitivity, Specificity, and Negative Predictive Value, which are crucial for evaluating the diagnostic accuracy of an IVD device.
  • Predicate and Reference Devices: The mention of predicate and reference devices with K numbers (which are FDA submission numbers for medical devices, including IVDs) further confirms its classification as a medical device, specifically an IVD given the context.

Therefore, based on the provided information, the HemosIL D-Dimer device clearly fits the definition of an In Vitro Diagnostic device.

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

A multi-center management study was performed at four hospitals on patients admitted consecutively to the emergency unit with suspected DVT or PE.
Data Source: 632 samples on an ACL TOP and 629 samples on an ACL ELITE.
Annotation protocol: Patients underwent a PTP (pretest probability) assessment using the Wells model and were classified as having a high, moderate, or low probability of DVT or PE. Patients with a negative D-Dimer test result and a low PTP score underwent no further diagnostic testing and were followed-up after 3 months for development of DVT or PE. For patients with a negative D-Dimer test result and a moderate PTP, it was the physician's decision whether to follow-up after 3 months or to undergo imaging techniques. Patients with a positive D-Dimer test result or a high PTP score underwent imaging techniques.

Performance Data:

A multi-center management study was performed at four hospitals on patients admitted consecutively to the emergency unit with suspected DVT or PE using representative IL Coagulation Systems: an ACL TOP (632 samples) and an ACL ELITE (629 samples). 302 patients on the ACL TOP and 298 patients on an ACL ELITE were suspected of DVT; 330 patients on the ACL TOP and 331 patients on the ACL ELITE were suspected of PE. As part of the study, patients underwent a PTP (pretest probability) assessment using the Wells model and were classified as having a high, moderate, or low probability of DVT or PE. Patients with a negative D-Dimer test result and a low PTP score underwent no further diagnostic testing and were followed-up after 3 months for development of DVT or PE. For patients with a negative D-Dimer test result and a moderate PTP, it was the physician's decision whether to follow-up after 3 months or to undergo imaging techniques. Patients with a positive D-Dimer test result or a high PTP score underwent imaging techniques.

There was one case during the study where a patient with a moderate PTP score and a negative D-Dimer test result on the ACL ELITE was confirmed for PE through imaging techniques. This same sample gave a positive D-Dimer test result on the ACL TOP.

The overall prevalence of DVT in the total population of samples was 19.5% (59/302) on the ACL TOP and 20.5% (61/298) on the ACL ELITE. The overall prevalence of PE in the total population of samples was 15.2% (50/330) on the ACL. TOP and 15.1% (50/331) on the ACL ELITE.

The sensitivity, specificity and negative predictive value (NPV) of HemosIL D-Dimer on the ACL. TOP and ACL ELITE for DVT and PE using the previously established clinical cut-off of 230 ng/mL is summarized below with the corresponding 95% confidence intervals (CI):
