Important Information 1. Read the method carefully. If you have any questions, contact the Study Director.

2. It is advised to make at least one practice run before the trial using your own materials so that you can minimize errors in manipulations. Check that all pipettes, equipment, and supplies are on hand and calibrated. 3. Begin the analyses on the specified date. Store the test portions according to the instructions. It is essential for the validity of the trial that all collaborators commence the analysis of each test portion on the designated day. Immediately upon receiving the shipment, confirm the contents with the Study Director by email. 4. THIS IS A STUDY OF THE METHOD, NOT OF THE LABORATORY. THE METHOD MUST BE FOLLOWED AS CLOSELY AS PRACTICABLE, AND ANY DEVIATIONS FROM THE METHOD AS DESCRIBED, NO MATTER HOW TRIVIAL THEY MAY SEEM, MUST BE NOTED ON THE REPORT FORM. 5. Report all of your results as soon as analyses are completed. Do not do more or less than indicated in the instructions. For example, do not do duplicate analyses and report the best or average result. More or fewer results complicate the statistical analyses and may invalidate your results. Data sheets are provided with instructions and indicate which results to report. A space is provided on the Data Report Form to indicate any deviations to the methods or deviations to the instructions to
