Staged Electronic Data Deliverable (SEDD)

The Staged Electronic Data Deliverable (SEDD) is a uniform data delivery format for analytical data. It is a hierarchal file created by a laboratory’s Laboratory Information Management System (LIMS) and contains information regarding the chemical analysis of samples. A SEDD file can be implemented in stages to better meet the needs of the customer. The CLP analytical Statement of Work determines the applicable SEDD Stage.

SEDD Stage 1

Stage 1 contains the minimum number of analytical data elements to convey results ONLY data to the end user (and is equivalent to the data on the current CLP Form I). SEDD Stage 1 includes:

• Information and data to check the completeness and compliance of sample condition upon laboratory receipt, and
• ONLY the analytical test results for requested samples.

SEDD Stage 2a

Stage 2a builds on Stage 1 by adding method Quality Control data. SEDD Stage 2a includes:

• Information and data to check the completeness and compliance of sample condition upon laboratory receipt,
• The analytical test results for requested samples, and
• ONLY sample-related QC results (e.g., laboratory control sample performance associated with field samples).

SEDD Stage 2b

Stage 2b builds on Stage 2a by adding instrument Quality Control data. SEDD Stage 2b includes:

• Information and data to check the completeness and compliance of sample condition upon laboratory receipt,
• The analytical test results for requested samples, and
• Both sample-related and instrument-related QC results.

SEDD Stage 3

Stage 3 builds on Stages 1 and 2 and adds additional measurement data to allow for independent recalculation of reported results. SEDD Stage 3 includes:

• Information and data to check the completeness and compliance of sample condition upon laboratory receipt,
• The analytical test results for requested samples,
• Both sample-related and instrument-related QC results, and
• Associated information from instrument outputs for recalculation of sample and QC results.
