From requisition to receipt: what must be true when a sample arrives
A practical guide to requisitions, acceptance criteria, chain of custody and the first messages a client should get.
Most intake problems start before the sample reaches the bench: an incomplete requisition, a label that does not match the form, a sample that arrived warm or late. This paper sets out what to capture, what to check, what to do when a sample fails the check, and how to keep clients informed without a phone call.
Who it is for: Lab managers, quality leads and intake staff at commercial environmental and building testing labs.

Can you show your work? Result integrity and audit trails in a testing lab
Accreditation, insurers, contractors and now regulators all ask the same question about a result: can the lab show where it came from and prove it has not been changed? This paper sets out where integrity is lost in practice, what ISO/IEC 17025 asks of your information systems, how to control spreadsheets and validate systems, and a self-check you can run this quarter.
Switching your lab system without stopping the lab
Most lab software projects go wrong before the first demo and after the contract is signed, not during the demo itself. This paper walks through how to write down your current workflow, score candidates fairly, decide what data to move, and cut over one workflow at a time while samples keep arriving.
