The laboratory requirements do not relax

Identity verification, correct tube, correct order of draw, processing window, temperature. All of it applies in a home exactly as it does at a site.

What changes is that the controls of a laboratory are absent, and the clock starts in a place with no centrifuge.

The stability window is the hard constraint

A sample drawn at 09:00 in a home, with a sixty-minute processing requirement, has to reach processing inside that hour.

That is a scheduling problem, and it must be solved before the visit is booked rather than discovered on the doorstep.

Know what happens between the home and the laboratory

Who transports it, in what, at what temperature, and how long it takes.

A sample handed to a courier is inside a chain you are accountable for and cannot see. Ask for the transit conditions and the times.

Identity checking is the nurse's job and your requirement

Two identifiers, confirmed against the requisition, in a house where the only person present is the participant.

Make sure the agency's process includes it and that their documentation shows it happened.

Labeling errors are the common failure

Labels printed in advance, a visit order changed, two participants in the same household. Household members enrolled in the same study are a real scenario and a real risk.

Missed and failed draws need recording

A draw attempted and unsuccessful is a documented event, not a non-event. It affects the endpoint and it may need a repeat inside the window.

The record has to reconstruct the visit

Who attended, when they arrived, what was drawn, at what time, how it was labeled, when it was collected for transport and by whom.

Nobody from the study was there. The report is the only account that will ever exist.
