Start with the decision, not the test
The first question is never "which test" but "who will read the result". A private answer for your own certainty and an answer that must satisfy an institution are handled differently.
Three common paths
- Personal / peace of mind. Standard collection, informative report, no chain of custody.
- Legal / official. Identity-verified, professionally supervised collection with documented chain of custody.
- Immigration. Requirements are set by the receiving authority and usually require an approved collection process.
Questions to answer first
- Who will need to accept this result?
- Which people can realistically provide a sample?
- Is there a deadline?
