A father-and-child product description tells you which participants are included in that offer. HomeDNA/DDC explains that adding the mother’s sample can be useful in some circumstances. Do not confuse the sample list with the separate question of who must authorize testing.
Start with the included participants
Our selected kit is described for one possible father and one child. Before adding another person, ask the laboratory whether extra materials, registration steps or charges apply. Do not put an additional swab into an envelope without the laboratory’s instructions, even when you believe it will make the analysis more complete.
Explain relevant circumstances privately
The laboratory may need more information to discuss a particular family situation. Provide that information in its approved case process rather than in a public review or a shopping-cart note. Ask directly whether the mother’s participation would help and what options apply when a requested participant is unavailable.
Keep consent distinct
A statement that a sample is optional is not permission to collect a child’s sample without the necessary authorization. The biological information needed for analysis and the authority needed to arrange testing are different issues. Resolve both before collection, particularly when family arrangements are disputed.
Get the plan in writing
Keep the laboratory’s instructions with the kit. Confirm the participant list, case registration, cost and return method before opening extra materials. This guide does not promise that every father-and-child case will be resolved in the same way, or that additional participants are included free of charge.
