8. Why does a sample submission form have to be completed for each matrix/analyte?
In order for the laboratory to ensure fast turn around time, each requested method should be on a separate submission form. The sample submission form may not be altered by FDA staff members unless the client has sent an email with instructions to do so. This is to prevent any misunderstandings that may arise due to changes on the forms. Separate test certificates are released for different analyses as they become available and by separating it on the sample submission form completed certificates will not be delayed by outstanding results as it will be released on its own certificate on completion. Results are withheld until all work requested on the sample submission form is completed.

9. Why is the LIMS administrator not authorized to send reports to an email address that is not indicated on the sample submission form?
Confidentiality of the results obtained by the laboratory is an ISO17025 requirement. It is therefore the policy of the laboratory that reports may only be sent to the email addresses indicated on the sample submission form. This serves as authorization on the part of the client to whom the results may be released. Be sure to indicate all email addresses on the sample submission form.
