NettetIn fact, only approximately half of the variability in aPTT results is explained by the heparin plasma concentration. Because of this variability, each institution is required to establish its own therapeutic aPTT range, which often ranges from … NettetTherapeutic anticoagulation interferes with most kinetic (but not DNA) tests. For specimens suspected of containing heparin, heparin is adsorbed using Hepzyme (Dade) reagent and the aPTT repeated. Additional Test Information: If sample undergoes heparin removal, this test is ordered by lab.

NettetIntroduction: Unfractionated heparin is widely used as an anticoagulant for extracorporeal life support (ECLS) and usually monitored with activated partial thromboplastin time (aPTT).
