26165 TEG Kaolin w/Heparinase

TEG Kaolin w/Heparinase
Test Code: TEGHEP
Synonyms/Keywords

​​Heparinase TEG, TEG

Test Components

​Kaolin TEG with Heparinase (R-H, K-H, ANG-H, MA-H, and LY30H)

Useful For

​Assessing if prolonged R (Reaction time) on standard TEG is due to circulating heparin.  TEG (Thromboelastograph) with Heparinase should be ordered along with the TEG assay when patient is on heparin. TEGHEP assay is also helpful to assess presence of heparin in patients post CABG when heparin rebound is suspected and for patients in cardiovascular surgery while on pump or when TEG6S is not available.

 Please refer to the 'TEG Manager®- Instructions for Access' for training and obtaining log-in information for remote viewing.
