Biobanking tissue for research
Biobanking is when patients agree that we can take extra tissue or bodily fluids during an operation, biopsy or blood test for research. A biopsy is when a doctor removes a small amount of tissue or cells to examine under a microscope.
Samples can include:
- tissues or cells that are taken during surgery but not needed for diagnosis
- extra blood or tissue while being taken for diagnosis or treatment
- pee, poo or saliva collected specifically for the biobank
Scientists analyse the extra material to find better ways of diagnosing, preventing and treating medical conditions. They can include heart disease and cancer.
Along with the extra tissue, the biobank also collects relevant information about each patient and their diagnosis.
When you come to our hospitals, we may ask you about donating samples to a biobank and giving us access to your medical information.
Your donated samples can help us better understand diseases that affect you and future generations.
Who can give samples
- Patients who come to our hospitals.
- Healthy volunteers.
Unfortunately, we cannot accept samples from all patients into our research biobanks.
For more information, please speak to the clinical staff who are looking after you.
How to give a sample
When you come to one of our hospitals, we may ask you about donating samples to a biobank and giving us access to your medical information.
If you have an operation, not all of the tissue is needed for diagnosis. We would like to ‘bank’ the unused pieces and use them for research.
If you have a biopsy or some blood taken, we would like to take a little bit more for a biobank.
Sometimes, we may also ask for saliva, urine or poo (stool) samples.
We may ask if you are willing to donate blood, saliva or urine samples if you come to clinics in the future. We can use these samples to monitor health and help to predict how well a treatment will work.
Participation is completely voluntary. Your decision does not affect your clinical care in any way.
We might give you more detailed information about a biobank at your appointment. You can ask us any questions.
How our research helps
Guy’s and St Thomas’ hospitals and our academic partner King’s College London manage biobanks that research specific conditions. These include:
- dermatology (skin conditions)
- infectious diseases
- thrombosis (a serious condition where one or more clots block the blood vessels)
- women’s health
Biobanks help scientists answer important questions about why conditions happen and who is at risk. The answers to these questions can lead to earlier, more accurate diagnosis and better treatment.
The same disease can affect individuals in various ways. Some people respond better to treatment than others. Scientists need to study samples from people with different ethnic and cultural backgrounds if they are to help all patients.
By using research biobanks, scientists can quickly access a large number of samples and information from the local patient population.
Giving your permission (consent)
We ask you to complete a consent form, which allows a biobank to collect samples and data. We also hope that you agree for us to collect extra samples from any future surgery you may have.
On some consent forms, you can choose the types of research that you’d like your samples to be used for.
Your data and confidentiality
At our biobanks, we put patients first. Patients might benefit from the research we support, but they are also essential in guiding our activities and making sure that the information we give is relevant.
We appreciate that there are times when being asked to donate to a biobank is not your priority. So, we work with patient representatives to reduce the impact on you, while ensuring we continue to comply with all the regulations.
We have a legal and moral duty to make sure that we do our research with the maximum respect for participants and their privacy.
We always ask for consent to use samples and access medical data.
When we give these samples to scientists, they are anonymised. We never release any information that allows you to be identified. We have robust systems to make sure that this does not happen.
Storing your samples and information
We collect information about you and your medical condition to add to the biobank database. This includes:
- details about your diagnosis, treatments and response to treatment
- family history
- other illnesses you have or medicines you take
- smoking and drinking habits
Collecting this data means we can identify patients who have similar conditions or have been treated in a similar way.
The samples are helpful in many different projects. For this reason, we would like to keep the samples until we have had a chance to use them. We may need to store the samples for more than 20 years.
If you change your mind, you are free to withdraw your consent at any time. We then dispose of any samples that we may still have in the biobank.
How your samples and data might be used
- Scientists from the NHS, universities and commercial companies (national and international) can apply to use samples and data.
- We may use your samples and data to find new biomarkers. They are substances that can predict how well a treatment will work. This may include examining genetic changes.
- For research where donated tissue samples are kept alive and grown in the laboratory or used in animal models, we always ask for specific consent.

Journey of a cancer biobank blood sample.
The King’s Health Partners Cancer Biobank at Guy’s and St Thomas’ collects samples and medical information from patients with and without cancer to support vital research. We only do this with consent. This is what happens.
[Visual: A member of staff holding an information booklet sits down in a chair next to a patient and starts talking to her. They look at the booklet together.]
We discuss what happens when you give samples and data to the biobank and how this helps research.
You are asked to sign a consent form.
[Visual: The patient signs a consent form and is given a copy. The scene changes to a patient talking to a different member of staff in a clinical room with a blue curtain drawn. A blood sample is taken.]
We take a little extra blood when you have your routine tests.
[Visual: A patient talking to a different member of staff in a clinical room with a blue curtain drawn. A blood sample is taken.]
Blood tubes are sent to the Biobank laboratory for processing.
Tubes are put in a machine that spins them very fast. This makes the blood divide into different parts.
[Visual: A member of staff walks down a hospital corridor carrying a red bag containing the samples. He enters the lab and hands the bag to a different member of staff wearing a white lab coat. She puts the tubes of blood into a machine and closes the lid.]
Each tube of blood is carefully removed and separated into smaller tubes.
[Visual: The same member of staff removes the tubes and uses a pipette to separate the samples carefully.]
From each tube of blood donated, more than 16 small tubes are created.
Tubes are coded. This means that researchers cannot identify you.
[Visual: A smaller tube is held up to camera showing a code and date on the label. The liquid no longer looks like red blood and is now a pale yellow colour.]
Tubes may be kept frozen, sometimes for several years, until a researcher needs them.
[Visual: A box containing the tubes are carried to a large freezer. Icy steam leaks out as the door is opened and the sample tubes are put one by one inside a drawer.]
Samples can be used to support cancer research anywhere in the world.

Subtitle: How 20ml (4 teaspoons) of blood from one patient can help 16 researchers
[Visual: An animated illustration begins to show how the samples can be processed and divided for research.]
10ml of blood (2 teaspoons) is encouraged to clot. This results in 4 smaller tubes of serum. They go to 4 researchers.
10ml of blood (2 teaspoons) is stopped from clotting. This results in 4 samples of plasma, 4 samples of white blood cells and 4 samples of red blood cells. They go to 12 researchers.
[Visual: The animation shows the samples being divided up and distributed to 16 researchers in total.]
