Spartan Cube CYP2C19 Inter Laboratory Reproducibility Study

The reproducibility study (VNV-00227) is aimed at assessing the performance of the Spartan Cube CYP2C19 product under multi-variant conditions that include test site, operators, testing days, and reagent lots. The sections below address how these variables were tested.

This study will be performed by a total of six operators at three test sites. At each site, two operators will conduct buccal sample collection and analysis. Operators include individuals who are technologists, technicians, and/or nurses. The buccal samples will be loaded in the Cube within one hour after buccal swab collection. Furthermore, results will be generated using multiple platforms (Spartan Cube, computer, and printer) and the same platforms will be used at each site. At each site, a total of 64 (8 subjects/operator x 2 operators x 2 sessions x 2 sub-sessions (replicates)) tests will be run on five non-consecutive days. Each day includes 2 sessions and 2 sub-sessions (total 4 collection times) in which samples will be collected. Test subject to platform pairing is not required, results will be generated on one of the platforms per session. This means that each site will generate a total of 320(64 obs./day x 5 days) results over the entire duration of the study.

To determine lot-to-lot reproducibility of test kits, three different lots will be evaluated. For this, two lots will be tested at each site. Each operator will use two lots per session on each testing day. Each replicate only includes a single lot of test kits.

All results generated by the Spartan Cube CYP2C19 System will be compared with the bi-directional sequencing results.
