The short answer
How long should you block out for the appointment?
Most first genetic counselling appointments run for about an hour. Some run closer to ninety minutes if your family history is large or complicated. A follow-up visit, once the family tree is already drawn, is usually shorter.
What makes it longer for some families
A big family with cancer on both sides takes longer to map than a small one. So does needing an interpreter, or bringing more than one relative who each has something to add. If a sample is being taken on the same visit, that adds a little more time at the end.
What makes it quicker for others
If you have already written down who was diagnosed and roughly when, the counsellor spends less time asking and more time explaining. A second visit to discuss a result is usually shorter again, because the family tree work is already done. Someone attending alone, with a small, well-remembered family history, is often finished well within the hour.
Why the clock is not the point
A genetic counselling session is not timed the way a routine clinic visit is. The counsellor's job is to leave with an accurate family tree and a clear plan, and that sometimes takes longer than either of you expected when you walked in. Treat the estimate as a guide for planning your day, not a promise of exactly how long the door will stay closed.
Nobody is rushed through this conversation. The time it takes is however long your family's history takes to go through properly.What fills the time
What actually happens across that hour
A genetic counselling appointment is not one thing. It is several conversations, one after another.
Taking the family history
The counsellor asks who in the family had cancer, which type, and roughly how old they were. This is usually the longest single part of the visit.
Explaining what the pattern might mean
Once the family tree is drawn, the counsellor talks through whether it looks sporadic, familial or hereditary, and why.
Talking through testing options
If a test is appropriate, you hear what it can and cannot tell you, which gene or panel makes sense, and who should be tested first.
Agreeing what happens next
The visit ends with a plan: whether to test now, wait, or bring another relative in first, and how the result will reach you.
Not sure whether this applies to you?
Ask an oncologistOn the day
How the appointment is structured, start to finish
Arrival and paperwork
A short registration, and a form asking for the basics of your family history in advance if you have not already sent one.
Building the family tree
The counsellor draws your family as a diagram while asking about each relative, going back at least two generations on both sides.
Discussing what testing could show
Once the pattern is clear, you hear whether a test is likely to be useful, what it looks for, and what a result would and would not change.
Deciding what happens next
You leave with either a plan to test, a plan to wait, or a clear reason why testing is not being recommended right now.
What changes the length
The variables that stretch or shorten a session
- Family size
- A large extended family with cancer on both sides takes longer to map than a small one.
- First visit versus follow-up
- A first visit builds the whole family tree. A follow-up usually only adds to it or discusses a result.
- Interpreter needed
- Working through a Telugu interpreter roughly doubles the time each question and answer takes.
- Number of relatives present
- Bringing a parent, a sibling and a spouse means three accounts to reconcile instead of one.
- Sample taken same visit
- If blood or saliva is collected at the end of the appointment, that adds a short amount of time.
- Consent discussion
- Deciding whether to receive secondary findings, or discussing storage of your sample, adds a further conversation.

Planning around it
How to plan your day around the appointment
Treat it as a morning or afternoon, not a quick errand between other things. If you are travelling from a district town, build in time for the return journey too, since the visit itself can overrun a little if the family history is detailed.
Bring the right people, not everyone
One or two relatives who know the family history well are more useful than a large group. If several people want to attend, it helps to agree beforehand who will do most of the talking.
Arrange an interpreter in advance if you need one
Telling the clinic ahead of time that you would prefer Telugu means an interpreter can be arranged, rather than the conversation slowing down on the day.
Keep the rest of the day light
Avoid stacking other errands straight afterwards, especially if you are hearing a lot of new information for the first time. Some families find it helps to sit somewhere quietly nearby for a few minutes before the journey home, rather than moving straight on to the next task.
A little preparation, mainly a written note of who was diagnosed and roughly when, is the single biggest thing that keeps the appointment moving.Commonly believed
Four things people assume about the timing
"It's just a quick chat before the blood test."
The conversation usually comes before any decision about testing, not after it. Most of the time is spent understanding your family, not drawing blood.
"If I bring the whole family, it will go faster."
More voices usually means more time, not less, because each person's account of the family history needs to be checked against the others.
"A shorter appointment means they didn't take it seriously."
A short follow-up is often short because the hard work of building the family tree was already done at the first visit.
"I can just send the family history by phone beforehand."
A written note in advance helps, but the counsellor still needs to ask follow-up questions in person to fill in gaps and check dates.
Questions we are asked
Common questions about appointment length
Will I get a test result at the first appointment?
No. The first appointment is almost always about your family history and deciding whether testing makes sense. A sample may be taken that day, but the result comes later, through a separate appointment.
Can I book a shorter slot if I already know my family history well?
Sending your family history in writing before the visit helps the counsellor prepare, but the appointment length is still set by the clinic to allow time for questions and for the testing discussion.
What if I need to leave early?
Tell the clinic when you book. The counsellor would rather plan a focused conversation around your time than rush through the family history and testing discussion together.
Does a video appointment take less time than an in-person one?
Not usually. The same family history has to be taken either way. A video appointment can be a little slower if the connection is poor or documents need to be shared on screen.
Is the follow-up appointment where I get my result?
Often, yes. Many clinics give results at a dedicated follow-up session rather than by phone, so there is time to explain what the result means and answer questions.
Why did my relative's appointment take longer than mine?
Family history length is the biggest factor. A relative with more affected family members, or a more complicated family tree, will usually need a longer conversation than someone with a simpler history.
Should I expect to wait beyond my booked time?
Clinics try to keep to schedule, but a family history conversation is not one that can be cut short. Build in some margin either side of your booked slot.
Can the appointment be split across two visits?
Yes, if the family history is large or if you need time to think before deciding about testing. Ask the clinic to split it if one sitting feels like too much.
