This device falls under the Hematology FDA review panel, regulated under 21 CFR 864.7320 - the FDA hematology device framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: Standard predicate-based submission. Standard predicate reliance. This clearance follows a standard predicate-based equivalence path within the Hematology review framework, consistent with the majority of Class II 510(k) submissions.

DAP Device Classification - Class 2, Special Controls

Product Code DAP Fibrinogen And Fibrin Split Products, Antigen, Antiserum, Control
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 864.7320
What this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. Clinical trial data may be submitted as supporting evidence to strengthen the substantial equivalence argument. Most Hematology devices follow this clearance model.

Started 2011-11-01 → Primary completion 2016-03-01 → Completed 2016-04-01
Primary outcome
To demonstrate the ability of STA Liatest DDi combined with a clinical pretest probability (PTP) to safely exclude pulmonary embolism or deep venous thrombosis in a 3 month follow-up
Secondary outcome
1. To analyse results homogeneity (inter-centers) in the group "positive D-dimer result and negative diagnosis" (descriptive statistics only). 2. To determine prevalence of VTE in PTP high patients based on imaging results
