Health products are usually built for an individual and then have family added later. That ordering is backwards for most of the world, where one person in a household does the medical administration for everybody in it.
The person holding the report is usually not the patient
It is an adult child holding a parent’s results. A spouse holding their partner’s. A parent holding a child’s. The person doing the understanding is frequently not the person the document is about, and a product that assumes otherwise forces everyone into one jumbled record.
Separate profiles, properly separate
Each person gets their own profile, so each person’s history belongs to them. Your father’s results sit in your father’s record, with his own history and his own trend over time — not merged into yours and not stacked in one undifferentiated pile.
That separation is also what makes the history meaningful. A trend across mixed-up results from four people is not a trend, it is noise.
Why this is a boundary worth enforcing
A family feature that is only a label on a shared record is how a teenager’s results end up visible to a parent, or a parent’s to a child, in situations where neither expected it. Profiles that are genuinely distinct are a privacy decision as much as a convenience.
