When people think about medical consent, they often picture a document handed over at the start of an appointment, a form to read, sign, and move on from.
But in genetics, informed consent is far more than paperwork.
At Rosalind Genetics, we believe informed consent is a conversation, not just a signature. It is one of the most important parts of the genetic counselling process because genetic information can have profound implications not only for an individual, but also for their family.
In simple terms, informed consent means making sure a person fully understands what a genetic test may, and may not, tell them before deciding whether to proceed. It is designed to support autonomous decision-making through a clear exchange of information between the clinician and the patient.
More Than a Test Result
Unlike many other medical tests, genetic testing can reveal information about future health risks, inherited conditions, reproductive risks, and sometimes unexpected findings unrelated to the reason the test was ordered.
For example, a person having hereditary cancer testing may discover an increased risk for multiple cancers, not just the cancer that prompted the referral. In some cases, the test may identify a variant of uncertain significance (VUS), meaning the result is unclear and not immediately actionable.
These nuances matter.
A signed form alone cannot ensure someone truly understands the possible outcomes, limitations, and emotional impact of testing. That is why informed consent in genetics must involve a detailed discussion about benefits, risks, limitations, possible results, privacy, and implications for relatives.
Genetics Is Family Medicine in a Unique Way
One of the most distinctive aspects of genetics is that results often extend beyond the individual.
A genetic test result may indicate that siblings, children, parents, or extended relatives could also be at risk of carrying the same genetic change.
This can raise important questions:
- Who in the family should know?
- How should that information be shared?
- What if family members do not want to know?
- What happens if the result affects reproductive planning?
These are deeply personal and sometimes emotionally complex issues. Informed consent provides the space to explore these questions before testing takes place.
The Right Not to Test
An important part of informed consent is recognising that choosing not to proceed with testing is also a valid decision.
Sometimes, after discussing the potential implications, a person may decide that now is not the right time. They may need more time to think, speak with family, or consider how the results could affect insurance, life planning, or emotional wellbeing.
This is not a failure of the process.
In fact, it is evidence that informed consent is working as intended; empowering people to make decisions that align with their values and circumstances.
Why Genetic Counselling Matters
At Rosalind Genetics, informed consent is a core part of our clinical approach.
Our role is not simply to organise testing. We help individuals and families understand what the testing means, what the possible outcomes are, and how those outcomes may influence medical care and family decision-making.
Genetics is rarely black and white. Good consent is about clarity, context, and compassion.
Because in genetics, consent is never “just a form.”
It is the beginning of an informed, supported, and meaningful healthcare journey.
