The AST Biotoxin unit was one of the first laboratories in Australia to gain NATA accreditation for PST testing using the “Boundy Method" for all shellfish types, including oysters, mussels, pipis, scallops, abalone, sea urchin roe, and rock lobster. The Boundy method has been recognised by ​the relevant regulartory bodies for Biotoxin analysis methods for Paralytic Shellfish Toxin (PST) (2020-02) - DAFF​

The Boundy method offers a number of improvements over the Lawrence method.  Primarily, the method produces “final" results from a single test, eliminating the need to do a follow-up “confirmation" test of potentially high results. Increased throughput in the laboratory is also achievable due to the decreased sample preparation requirements.

The method underwent an international inter-laboratory trial, published in the Journal of AOAC​​. The AST Biotoxin unit was very proud of the fact that we were the only Australian participant in the trial and that we provided a major improvement that increases instrumental robustness that is now acknowledged as part of the official method.

From a grower, client, or regulator perspective, sample requirements remain the same (250mL polycarbonate container with yellow label) and reports and SMSs continue to be sent. The PST testing is​ no longer be separated into “screen" and “confirmation" components.
