HEPTEM

General Information

Alias: Rotem

Performed: 24/7

Turn Around Time: 1 hour

CPT Codes: 85396

Performed By: Rapid Response Lab

Notes:

The HEPTEM assay is a semi-quantitative in vitro diagnostic assay used on the ROTEM® delta Thromboelastometry System to monitor the coagulation process via the intrinsic pathway in the presence of unfractionated heparin in citrated whole blood specimens. Coagulation evaluations with the ROTEM® delta system are commonly used to assess clinical conditions in organ transplantation, cardiovascular surgery, cardiology procedures and trauma to assess post-operative hemorrhage and/or thrombosis.

Clinical Utility: HEPTEM is only indicated if there is suspected heparin present in the INTEM sample.  It should not be performed for routine ROTEM testing when there is no suspicion of heparin present within the INTEM test. Please note that the reference ranges for the INTEM test can be applied to this assay.
