Intrinsin LS & LR - APTT Reagents

The activated partial thromboplastin (APTT) test can be used to detect factor deficiencies, monitor anticoagulants such as heparin and anti-thrombin agents, to assess resistance to activated protein C and detect antibodies against clotting factors in mixing tests. It can also be used to detect lupus inhibitors which interfere with the low, rate-limiting level of phospholipid in the Intrinsin-LS reagent. Intrinsin-LR contains excess phospholipid and is therefore more resistant to these agents.
