Data & preparation
Preparing a sample for lab qualification — Sell Data to Lab
ANSWER IN BRIEF
Create a lab sample from an agreed review specification, with a reproducible selection and clear limits on what its results can establish.
Write the sample request down
Record the purpose, required fields, format, coverage and expected decision. Ask who will review it and who will receive the results. Clarify whether the request is a format check, a representative evaluation or a curated demonstration, because each calls for different selection and interpretation.
Select against the agreed scope
Choose records using a documented rule and retain the selection manifest. Include relevant variation and known exceptions when the review is meant to assess the full collection. If constraints prevent a representative sample, explain the limitation rather than replacing missing categories with unusually favorable examples.
Package the interpretation notes
Include field definitions, units where applicable, provenance, selection method and known gaps. State which fields have been removed or transformed. These notes allow the reviewer to distinguish source characteristics from preparation decisions and reduce the chance that technical questions become repeated requests for larger unexplained exports.
Agree the review closeout
Confirm access, handling and the feedback expected at the end of the review. Ask for a decision tied to the original question and record any new requirements separately. DataVal’s initial estimate does not need a raw-data upload; sample preparation should follow a qualified enquiry rather than precede every introduction.
Questions & answers
What if the lab asks for a larger sample repeatedly?
Ask what unresolved question requires the expansion and agree its scope, handling and commercial implications before sending more.
