Our newest product is DOAC Stop; a vital tool for any lab troubled by the new or direct oral anticoagulants. DOAC Stop removes all DOACs from sample plasmas without affecting other tests of haemostasis. Its effect is best measured using our uniformly-sensitive RVV-based DOAC-Test reagent and it complements our HEP-Stop (HRRS) for investigating unexpectedly prolonged APTT results. For lupus anticoagulant testing we have liquid stable dRVT-LS (LA Sensitive) and dRVT-LR (LA Resistant) reagents with "LS/LR" ratios being unaffected by VKA (Warfarin) or DOACs. There is also SACT II, a non-settling alternative to the classic kaolin clotting time (KCT) reagent and the Intrinsin APTT reagents; LA Sensitive and LA-Resistant. All these can be supplied ready for use or as powders for your own reconstitution. Our factor Xa- activated clotting time (XACT) test kit detects procoagulant phospholipids such as those on microparticles and activated platelets. We can supply synthetic phospholipid blends and also other procoagulant products such as soluble ellagic acid and equine collagen.


Dilute Russells Viper Venom Test


We have expertise in developing internationally recognised dRVVT, KCT and SACT tests for lupus anticoagulant, tests for activated protein C resistance and the protein C pathway for other organisations. Now we are involved in the design and evaluation of new methods for blood coagulation testing, principally for studying hypercoagulability and in research on acquired inhibitors of coagulation.

LA sensitive dRVT-LS and lupus resistant dRVT-LR reagents are available in powder form for preparation of liquid "ready for use" reagents. These reagents are colour coded (green for "screen", LA Sensitive; pink for "confirm", LA Resistant) and are stable for up to 2 years at 4°C. Results are more reliable than those from regeants of other suppliers (Comparative data from external evaluations are available on request). The LS/LR combination shows no false positive results on samples containing NOACS or plasmas from warfarin patients.
