Standard Guide for Certification Requirements for Analytical Laboratory Professional Vocations Within the Cannabis Industry

AbstractOver the period from December 3rd, 2019 to March 13th, 2020, after the urgent field safety notice reported by Roche, we performed double determinations of all troponins from the same tube in parallel and in the same run. We used the same Elecsys troponin T hs reagent (ref 08469873190), first result was obtained with the current hs-cTnT application (18 min) and the second measurement was with the STAT application (9 min). On the 11,388 results in the range from 3 to 500 ng/L, we observed 4.18% discordant results (above 18.8% RCV). Overall, we observed an overestimation of the hs-cTnT STAT assay. The Elecsys Troponin T hs STAT assay demonstrated good analytical performances on Cobas e801 analyzer. However, its use according to the ESC recommendations for the 0 h/1 h algorithm should be carefully evaluated and requires further studies with serial cTn testing.

Certification Requirements

The Aasta Hansteen spar in the Norwegian Sea is designed to be moored with a taut polyester rope mooring system. The water depth at the field is 1300 meters, and due to the short installation season the most efficient hookup is with pre-installed mooring lines, which require the mooring lines to be laid down on the seabed. DNV certification does not allow seabed contact for polyester ropes unless proven that no soil ingress and damage takes place. To be able to certify the ropes Statoil developed a test method including contact with soil, rope movement and forced water flow through the filter construction. Full scale tests were performed with actual rope and Aasta Hansteen soil, both in laboratory and at site. This paper discusses the certification requirements and presents adequate qualification test together with results from testing.
