Ecarin Clotting Time

Product Code
Definition
The TAS ECT Test Card is to be used with the TAS Analyzer and is intended to determine the anticoagulant effect of hirudin during CBP in patients who have HIT. It is suited for professional use in decentralized areas of testing near the site of patient care as well as for use in the more traditional laboratory. Monitoring with the TAS ECT is indicated for persons who have been identified with and/or confirmed as a high risk for HIT, and require high dose anticoagulant with hirudin for a scheduled or emergency CPB procedure.
Physical State
The system requires pooled normmal human plasma to dilute the citrate whole blood usingpolypropylene plastic tube. The system's performance is monitored by two levels of quality control plasma avialble from Cardiovascular Diagnostics, Inc.
Technical Method
The TAS ECT provides one stage test which measures the clotting time of a plasma diluted, citrate whole blood after combining it with the prothrombin activator, ecarin. It is composed of a thin plastic card in which a flat, shallow reaction chamber containing all reagents necessary for the ECT test. In the reaction chamber, it also contains paramagnetic iron peroxide particles (PIOP) which is impeded by a clot. The signal produced by the relative movement of the PIOP is interpreted by the TAS Analyzer and reported in seconds. The greater amount of recombinant hirudin in the patient blood, the longer the clotting time is generated by the TAS system.

No Linked CFR Text

The FDA has not linked product code PBA to any particular section of the CFR (Code of Federal Regulations). There are multiple reasons why this might be the case:

  • The product code was created for a class III submission that does not follow the normal PMN or PMA path - e.g., for a device that falls under HDE (Humanitarian Device Exemption) or EUA (Emergency Use Authorization).
  • The FDA has generated the product code for an existing Class III device, as a result of a PMA supplement that modifies the device in a way that it can't fit under the existing product code originally assigned
  • The product code was created for internal use at the FDA, and not for classification or regulatory-related purposes.
