Arranging blood donors before liver surgery: a family guide | CION Cancer Clinics
Hospitals in India often ask families to bring blood donors before liver surgery. Their blood usually replaces stock in the blood bank, and many people having a liver resection need no transfusion at all. This page explains what the hospital is asking for, who in the family can safely donate, why a close relative is not always the right donor, and how to arrange it without a last-minute rush. At CION Cancer Clinics, a multidisciplinary tumour board weighs your liver function and your scans before recommending any treatment.

The short answer
Why is the family asked to arrange blood donors before liver surgery?
Many hospitals in India ask the family to bring healthy people to donate blood before a major operation. The blood they give usually goes into the blood bank's shared stock, which replaces what your relative may use during or after liver surgery.
Most people do not need much blood
Liver surgery has become far less bloody than it once was. Surgeons and anaesthetists now use careful techniques to limit bleeding, and many people having a liver resection need no transfusion at all. The donor request is a precaution and a way of keeping the blood bank stocked for everyone. It is not a sign that the team expects heavy bleeding. Our page on blood loss and transfusion in liver surgery explains when blood is actually given.
Who this page is for
This page is for families of someone booked for a liver resection for primary liver cancer or for cancer that has spread to the liver. Liver transplant planning is different and is covered on its own pages. Blood donation is not liver donation. Nobody is being asked to give part of their liver here.
What the blood bank asks for
What exactly will the hospital ask the family to arrange?
Requests vary between hospitals. These are the four you are most likely to hear about, and what each one means.
Replacement donors
Relatives or friends of any blood group give a standard donation at the blood bank. Their blood joins the stock. Your relative receives matched blood from that stock if it is needed.
A blood sample from the patient
Before the operation, the blood bank tests your relative's group and keeps a sample to cross-match against. This is done by the hospital, not by the family.
Platelet donors
People with cirrhosis sometimes have a low platelet count. If the team thinks platelets may be needed, they may ask for donors who can give platelets by a longer machine donation called apheresis.
Platelet donors often need to match the patient's group more closely, so the blood bank will tell you which groups to bring.Plasma
Plasma is the liquid part of blood that helps it clot. It comes from the bank's stock. Families are not usually asked to arrange plasma donors separately.
Not sure whether this applies to you?
Ask an oncologistStep by step
How do we arrange donors without last-minute panic?
Ask the team early, in writing
Once the operation date is set, ask how many donors are requested, whether platelet donors are needed, and which blood bank they should go to. Your team will tell you where the operation takes place.
Make a list wider than you need
Some volunteers will be turned away on the day after the health check. List more people than requested, including cousins, colleagues and friends, and ask them to keep the date free.
Send donors with the patient's details
Each donor should carry photo identity and a slip with the patient's full name, hospital number and ward. The blood bank uses this to credit the donation against your relative.
Keep the donor receipts
The blood bank gives a slip or card for each donation. Keep them together with the admission papers. You may be asked for them at discharge.
Ask about voluntary donor groups
If your family is small or lives far away, ask the blood bank about voluntary donor groups. See our page on blood banks and platelet donors in Hyderabad.
At the blood bank
What do the words on the blood bank form mean?
- Group and save
- The bank records your relative's blood group and keeps a sample, so blood can be matched quickly if it is needed.
- Cross-match
- A test that checks a sample of the patient's blood against a donor bag to make sure they are safe together before any transfusion.
- Packed red cells
- The part of blood that carries oxygen. This is what most people mean when they say "a bottle of blood".
- Apheresis
- A donation where a machine collects only platelets and returns the rest of the blood to the donor. It takes longer than a normal donation.
- Directed donation
- Blood given by a relative for the patient directly. Many banks avoid this or treat the blood specially, for safety reasons explained below.

One field. No form to fill in, and no charge for the call.
Commonly believed
Is blood from a close relative the safest choice?
"Blood from a son or brother is safest for him."
Not always. Blood from a close blood relative can, rarely, cause a serious reaction in the person receiving it. Blood banks either avoid this or treat the bag first. Matched blood from the general stock is usually the safer choice.
"If we cannot find donors, the operation will be cancelled."
National policy in India favours voluntary donation and discourages refusing blood for want of a replacement donor. Practice still varies. If you are struggling, tell the team early rather than on the morning of surgery.
"We can pay someone to donate on our behalf."
Paid or professional blood donation is not allowed in India. Never pay a stranger who offers to donate for money. It is illegal and the blood may not be safe.
"A relative with hepatitis B can still donate if they feel well."
They cannot. Every donation is screened for infections, including hepatitis B and C. This is a safety rule, not a judgement, and it is a good reason for that relative to see a doctor about their own liver.
Before you ask someone
Who in the family should not volunteer to donate?
The blood bank does a short health check and a questionnaire on the day. It decides who can donate, not the family. You can save everyone a wasted trip by knowing who is likely to be deferred.
People commonly turned away
Anyone who feels unwell, has a fever or a cold, or has a low blood count is usually asked to come back later. So are people who are underweight, pregnant or recently gave birth, have had a recent tattoo or piercing, or take certain medicines. People with hepatitis B or C, HIV or some heart conditions cannot donate. Very young and older volunteers fall outside the donation age limits. The blood bank will explain its exact rules.
Do not pressure anyone
A relative who says no may have a private health reason. Donation must be voluntary and honest. A donor who hides a condition puts your own relative at risk.
Ask each volunteer to eat a normal meal and drink water before donating, and to bring identity.Being straight with you
What this page cannot tell you
It cannot tell you how many donors your relative's hospital will ask for, or whether your relative is likely to need blood. That depends on the size and position of the tumour, the type of operation planned, the health of the rest of the liver and the blood tests done beforehand. Your surgical team decides this once the tests before liver surgery are complete.
Who this does not apply to
Families preparing for a liver transplant face a different and larger blood plan, set by the transplant centre. People having TACE, ablation or radiation instead of surgery rarely need donors at all.
Where CION fits
CION's surgical oncologists plan the operation and will explain the blood bank's request and how to meet it. The blood bank belongs to the hospital where the operation takes place, and its rules are the ones that count. For background on bleeding during the operation itself, read bleeding risk during liver resection.
Questions we are asked
Common questions about blood donors for liver surgery
Do donors need the same blood group as the patient?
For ordinary replacement donation, usually not. The donor's blood goes into the shared stock and your relative receives matched blood from it. Platelet donors are different, and the blood bank may ask for particular groups. Always ask the blood bank which groups it wants before people travel.
When should donors come to the blood bank?
Ask the blood bank. Many prefer donors around the time of admission, so the stock is fresh and credited against the right patient. Platelets keep for only a short time, so platelet donors are usually called much closer to the day they may be needed.
Will my relative definitely need a transfusion?
No. Many people having a liver resection need none. Arranging donors is a precaution. The chance rises with larger operations, cirrhosis, a low platelet count or a low blood count before surgery. Your surgeon can tell you whether your relative is in a higher group.
Is it safe for the donor?
For a healthy adult who passes the blood bank's check, donating is a routine, safe procedure. Some people feel faint briefly afterwards. The body replaces the fluid quickly and the red cells more slowly. Donors should rest, eat and drink, and avoid heavy work that day.
Can women in the family donate?
Yes, if they pass the health check. Women are more often deferred for a low blood count, and are deferred during pregnancy and for a while after delivery or while breastfeeding. Let the blood bank make the decision rather than ruling anyone out at home.
Our family lives in a district far from Hyderabad. What can we do?
Tell the team as early as possible. Ask whether a donation at a licensed blood bank near your home can be credited, and ask about voluntary donor groups in the city. Friends and colleagues living in Hyderabad can also help. Do not wait until the day of admission.
Is there a charge for the blood itself?
The donation is given freely, but blood banks charge processing fees for testing, separating and storing each bag. These vary by hospital and by scheme cover. Ask for these charges to be shown in the written estimate for the operation.
Who can explain our hospital's blood request?
Your surgical team and the hospital's blood bank. CION's surgical oncologists will go through what is being asked and why. If you are unsure what the request means, call the CION helpline and someone will help you make sense of it.
