This is an FDA 510(k) clearance letter and an Indications for Use statement, not a scientific study report. Therefore, it does not contain the detailed information needed to describe acceptance criteria and a study proving a device meets those criteria in the format requested.
The document states:
- Device Name: GTI-PF4 ELISA
- Intended Use: "as an in vitro diagnostic kit by hematology, coagulation or other pathology laboratories to assist in screening patient samples for the presence of heparin-associated antibodies commonly found in patients with heparin-induced thrombocytopenia or thrombosis."
- Regulatory Class: II
To answer your request, a comprehensive study report or a 510(k) summary would be required. The provided text only informs that the device has received 510(k) clearance based on substantial equivalence to a predicate device, but it does not detail the specific performance studies, acceptance criteria, or ground truth methodologies used by the manufacturer to demonstrate that equivalence.
§ 864.7695 Platelet factor 4 radioimmunoassay.
(a)
Identification. A platelet factor 4 radioimmunoassay is a device used to measure the level of platelet factor 4, a protein released during platelet activation by radioimmunoassay. This device measures platelet activiation, which may indicate a coagulation disorder, such as myocardial infarction or coronary artery disease.(b)
Classification. Class II (performance standards).
