Limitations
Please refer to procedure "Point of Care Hepcon Hemostasis Management System (HMS)" Section 8.
Heparin Assay (HPT): If all four channels clot before 30 seconds, the blood sample may be activated, and channel clotting time resolution may not be great enough to give a reliable answer. Run times greater than 249 seconds may indicate the heparin level of the blood was higher than the range of the cartridge, the expiration date has been exceeded, or the cartridge was improperly handled or stored.
High-range Activated Clotting Time (HR-ACT): When on cardiopulmonary bypass, several factors can influence the performance of the HR-ACT.
Heparin Dose Response (HDR): Individual responses to heparin vary considerably.
