The summary describes a standard immunoassay and automated analyzer, with no mention of AI or ML in the device description, intended use, or performance studies. The use of a "clinical Pre-test Probability Assessment (PTP) model" is mentioned, but this refers to a clinical assessment model used in conjunction with the assay, not a component of the device itself.
No
The device is an immunoassay for the quantitative determination of D-dimer in plasma, used as a diagnostic aid in conjunction with clinical assessment for DVT and PE, not for treating or preventing disease.
Yes
The device is described as an immunoassay for the quantitative determination of D-dimer, used in conjunction with a clinical Pre-test Probability Assessment (PTP) model to exclude deep vein thrombosis (DVT) and assess patients suspected of pulmonary embolism (PE). This indicates its use in making a medical diagnosis.
No
The device is a homogeneous latex particle based immunoassay, which is a laboratory test involving physical reagents and an automated analyzer, not solely software.
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 crosslinked fibrin degradation products containing the D-dimer domain in citrated human plasma." This involves testing a biological sample (human plasma) in vitro (outside the body).
- Device Description: The description details a "homogeneous latex particle based immunoassay" that analyzes a sample of "citrated human plasma." This confirms the in vitro nature of the testing.
- Clinical Performance: The performance study describes testing on "citrated human plasma" samples from patients.
The core function of the device is to analyze a biological sample in vitro to provide diagnostic information, which is the definition of an In Vitro Diagnostic device.

Device Description
bioMerieux Inc. MDA® D-Dimer is a homogeneous latex particle based immunoassay for the quatitative determination of cross-linked fibrin degradation products containing the D-dimer domain in citrated human plasma.
MDA D-Dimer is a quantitative homogeneous-phase immunoassay using latex microparticles to photo-optically detect binding of specific monoclonal antibody to D-dimer. These latex particles aggregate in the presence of fibrin derivatives containing the D-dimer domain. The rate of latex microparticle aggregation is proportional to the concentration of D-dimer in the sample. D-dimer concentration may be interpolated from a reference curve.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Comparison Data:
Accuracy
Results from MDA D-Dimer reagents obtained on an MDA were compared with a commercially available assay (Fibrinostika® FbDP EIA)for detection of crosslinked and non-crosslinked fibrin degradation product containing the D-dimer. Specimens were tested in duplicate according to NCCLS Approved Guideline EP9-A. The following results for slope, intercept and correlation were observed for linear least squares regression comparing MDA D-Dimer (y-axis) and the reference method (x-axis):
Reference Method: Fibrinostika® FbDP EIA, n: 175, Slope: 1.005, Intercept: 0.293, r: 0.91
Precision
Total precision and within-run precision for the MDA D-Dimer assay were determined in accordance with NCCLS Tentative Guideline EPS-T2.30 Controls were tested in duplicate on an MDA instrument twice daily. Data were collected for 20 days, with a minimum of 40 runs and 80 measurements at each control level. The following precision was observed:
Sample: Positive Control, Mean (ug FEU/ml): 1.51, SD (within-run) (ug FEU/ml): 0.06, CV (within-run) (%): 3.83, SD(total) (ug FEU/ml): 0.10, CV(total) (%): 6.67
Sample: MDA Verify 1 (Normal Control), Mean (ug FEU/ml): 0.28, SD (within-run) (ug FEU/ml): 0.02, CV (within-run) (%): 6.97, SD(total) (ug FEU/ml): 0.04, CV(total) (%): 12.65
Clinical Performance:
A multi-center, prospective cohort study was designed to validate the diagnostic utility of the MDA D-Dimer assay to exclude a diagnosis of deep vein thrombosis (DVT). Consecutive eligible outpatients (n = 556) with a first suspected DVT episode were evaluated at three hospitals. Using a previously validated standardized clinical model to estimate the probability of DVT, patients were classified as having a high, moderate, or low pre-test- probability -(PTP) of DVT, and had an MDA D-Dimer test performed on presentation.
The D-Dimer assay was performed without knowledge of the PTP assessment results. A clinical cut off value of 0.50 ug FEU/ml previously validated in an accuracy study. A D-Dimer result of >0.50 µg FEU/ml was considered positive, and a result of

A description of the device(System) (a) (4)
bioMerieux Inc. MDA® D-Dimer is a homogeneous latex particle based immunoassay for the quatitative determination of cross-linked fibrin degradation products containing the D-dimer domain in citrated human plasma.
D-dimer containing fibrin degradation products (FbDP) fragments are released when cross-linked fibrin is degraded by plasmin. Cross-linked fibrin is formed when fibrionogen is cleaved by thrombin to form fibrin monomers, which then spontaneously polymerize and are cross-linked by Factor XIIIa. Thrombin is required to cleave fibringen as well as to activate Factor XIII. Plasmin formation is triggered when a fibrin clot is formed. Plasmin degrades some of the cross-linked fibrin and the resulting level of D-dimer is, therefore, an indirect measure of thrombin generation and subsequent clot formation.
D-dimer is elevated in disseminated intravascular coagulation (DIC), deep vein thrombosis (DVT), pulmonary embolism (PE), sickle cell crisis, pre-eclampsia, some cause of unstable angina, myocardial infarction, some cancers, and following major surgery or trauma.
MDA D-Dimer is a quantitative homogeneous-phase immunoassay using latex microparticles to photo-optically detect binding of specific monoclonal antibody to D-dimer. These latex particles aggregate in the presence of fibrin derivatives containing the D-dimer domain. The rate of latex microparticle aggregation is proportional to the concentration of D-dimer in the sample. D-dimer concentration may be interpolated from a reference curve.
