![]() ![]() Taronga Zoo has four of these rare creatures on display in its Reptile World exhibit – don’t miss your chance to see the most toxic snake in the world. The Inland Taipan has a conservation status of ‘Rare’ in Queensland, and ‘Presumed Extinct’ in New South Wales and Victoria. Prey is attacked with a series of rapid strikes which cause almost instant paralysis. The venom of the Inland Taipan contains a powerful neurotoxin, combined with a ‘spreading factor’ enzyme that increases the rate of absorption. They’re a shy, reclusive snake that would rather stay tucked away in cracks and crevices in the soil of arid central Australia than face the harsh light of day where they rarely encounter people. Although several bites have been recorded in Australia, none have ever proved fatal. The Inland Taipan, also known as the ‘fierce snake’, is famous for its potent poison. It’s the world’s most poisonous snake, capable of killing 100 men with just one drop of venom – and a 17-year-old Hunter Valley teenager has recently survived a bite.

Like other lupus anticoagulant tests, it does not seem to have a 100% detection rate, but this may be due to the presence of lupus anticoagulant subtypes with distinct activities or the requirement of cofactors other than prothrombin or beta 2 glycoprotein-I. The TSVT was influenced by the presence of heparin but was not sensitive to the effects of oral anticoagulant. CONCLUSIONS-The TSVT showed satisfactory intra-assay precision and reasonable sensitivity to lupus anticoagulant, compared with the DRVVT. Fourteen of 17 patients known to have lupus anticoagulant (on the basis of DRVVT results) were also positive by the TSVT two of the remaining three were borderline and one was negative. Some anticoagulated plasmas showed correction in the PNP and were regarded as false positive. The TSVT in plasmas from patients receiving heparin correlated with the heparin concentrations (as measured by the APTT, r2 = 0.81). The patients with mild liver dysfunction all had normal TSVTs. Of these, five corrected on mixing with normal plasma and two gave equivocal results. In 43 samples from patients receiving oral anticoagulants there was no correlation between level of anticoagulation and TSVT, and only seven samples had increased TSVTs. Results were considered positive for lupus anticoagulant if the ratio was > or = 1.1 and was reduced by > or = 10% or to < 1.1 in the PNP. RESULTS-The optimised conditions for the TSVT were established and a reference range was determined in normal healthy subjects. The TSVT was used to test plasmas from patients receiving oral anticoagulant or heparin with mild liver dysfunction and with documented lupus anticoagulant. METHODS-A coagulation test based on the Taipan snake venom time (TSVT) with a platelet neutralisation procedure (PNP) was developed and compared with dilute Russell's viper venom time (DRVVT). AIMS-To develop a specific test for lupus anticoagulant activity with reduced sensitivity to coagulation factor deficiency that would be suitable for analysis of plasmas from patients receiving oral anticoagulants. ![]()
