Who can donate blood in India? | CION Cancer Clinics
Most healthy adults in India can donate blood if they are aged 18 to sixty-five, weigh at least 45 kg, have a haemoglobin of at least 12.5 grams per decilitre and feel well on the day. A tattoo, a recent delivery or an illness usually means waiting, not a lifelong no. Some conditions, such as HIV, hepatitis B or C and any past cancer, rule you out. The blood bank doctor makes the final call. At CION Cancer Clinics, our haematologist cares for anaemia, bleeding, clotting and inherited blood disorders, with ArogyaSri, CGHS and cashless insurance accepted.

The short answer
Can I donate blood in India?
Most healthy adults can. Under the national guidelines, you need to be aged 18 to sixty-five years, weigh at least 45 kg, have a haemoglobin of at least 12.5 grams per decilitre (g/dL) on the day, and feel well when you walk in.
Who sets these rules
The rules come from the National Blood Transfusion Council, which works under the Union health ministry. Every licensed blood bank in Telangana and Andhra Pradesh follows them. A blood bank may be stricter than the guidelines on a given day, but it cannot be looser.
Why the rules exist
The checks protect two people. They protect you, so that giving blood does not leave you weak or dizzy. They also protect the person who will receive it, who is often a child with thalassaemia, a woman who bled after delivery, or someone on treatment for leukaemia. Many of the waiting periods exist because an infection can be in the blood before any test can find it.
A "no" is usually a "not today"
Most people who are turned away are turned away for a while, not for ever. A low haemoglobin, a recent fever or a new tattoo all mean you can come back later. Only a small group of conditions rules you out for life.
The blood bank doctor on the day makes the final decision. This page explains the usual rules. It cannot say yes or no for you.The four basics
What will the blood bank check before I donate?
Every donor goes through the same short checks. If any one of them is not met, you will be asked to come back another time.
Your age
You need to be between 18 and sixty-five years old. Many blood banks will not take a first-ever donation after sixty, because they have no record of how you managed it.
Carry a photo ID. Some camps ask for it.Your weight
At least 45 kg lets you give a smaller bag of 350 millilitres. The larger bag of 450 millilitres needs at least 55 kg. The amount taken is matched to your size so that your body copes with it easily.
Your haemoglobin
Haemoglobin is the part of blood that carries oxygen. It must be at least 12.5 grams per decilitre on a quick finger-prick test before you donate.
Worth knowing
- A finger-prick reading can differ from a lab report
- Reference ranges vary between laboratories
- One low reading is not a diagnosis
How you are on the day
Your pulse, blood pressure and temperature are checked. You should have eaten a normal meal, slept the night before and have no fever, cough or loose motions. Coming in unwell is the most common reason for a same-day refusal.
Not sure whether this applies to you?
Ask an oncologistCome back later
How long do I wait after a tattoo, a delivery or an illness?
If this applies to you
The usual wait before donating
A tattoo, ear or body piercing, or acupuncture
Twelve months
Giving birth, or still breastfeeding
Twelve months after delivery, and not while breastfeeding
A miscarriage or termination of pregnancy
Six months
Malaria, once fully treated
Three months after you are well
Receiving a blood transfusion yourself, or major surgery
Twelve months
Dengue, typhoid, jaundice or another recent illness
Ask the blood bank. The wait depends on the illness and when you recovered
On the day
What happens between walking in and giving blood?
The form
You fill in a donor questionnaire about your health, medicines, travel, recent illnesses and anything that might carry an infection risk. Answer honestly. It is confidential, and it protects the person who will receive your blood.
The short check-up
A staff member checks your weight, pulse, blood pressure and temperature. The medical officer reads your form and asks a few questions about anything that is unclear.
The finger-prick
A drop of blood from your fingertip checks your haemoglobin and blood group. If the reading is low, you are thanked and asked to come back once it has recovered.
The donation and rest
The needle goes into a vein in your arm and the bag fills in a few minutes. You then rest, drink something and eat a snack before you leave.
Leave a number, we will call you
One field. No form to fill in, and no charge for the call.
Commonly believed
What do people wrongly believe keeps them from donating?
"I have diabetes, so I can never give blood."
Not always. Many people whose sugar is well controlled on tablets or diet are accepted. People who need insulin are usually not accepted. Take your medicine list with you and let the medical officer decide. Do not change or skip a medicine to pass the check.
"Women should not donate. They are always low in blood."
Women donate safely every day. The same haemoglobin check applies to everyone. You will be asked not to donate during your period, while pregnant, or while breastfeeding, and women wait longer between donations than men.
"I took a tablet for a headache, so I am out."
A simple painkiller or a blood pressure tablet does not rule you out for whole blood. Some medicines do matter, such as blood thinners, some acne and hair-loss medicines, and antibiotics for an active infection. Mention everything on the form.
"If they turned me away once, I can never donate."
Most refusals are temporary. A low haemoglobin, a cold, a recent tattoo or a late night can all mean a later visit works. Ask the blood bank why, and when you may return.
On the slip
What do the words on a donor card or deferral slip mean?
- Temporary deferral
- You cannot donate today, or for a set time. You are welcome back after that.
- Permanent deferral
- A condition in your history means your blood should not be given to someone else. It says nothing about how healthy you are day to day.
- Voluntary donation
- Blood given freely, with no payment and no named patient. Selling blood is illegal in India.
- Replacement donation
- Blood given by a family member or friend to replace units a patient has used. The same eligibility rules apply.
- Apheresis
- A donation where a machine keeps one part of your blood, such as platelets, and returns the rest to you. It has its own extra checks.
Being straight with you
Who should not donate at all?
Some people are never accepted, because their blood could harm the person who receives it or because donating could harm them. This is not a judgement about you.
Conditions that usually rule you out for life
These include HIV, hepatitis B or hepatitis C, and any cancer, including leukaemia and lymphoma, even if treatment finished long ago. Serious heart, kidney or liver disease, epilepsy on treatment, and bleeding disorders such as haemophilia also rule you out. So does thalassaemia major. People with thalassaemia trait are often accepted if their haemoglobin passes the check.
If you are a patient yourself
If you are being treated for a blood disorder or anaemia (a low haemoglobin), do not donate. Your own blood count matters more. If a family member needs blood at a hospital, ask the blood bank how others in the family can help instead.
What this page cannot tell you
Rules are revised, and the full list of conditions and medicines is longer than any web page. Your own history may need a doctor to weigh it. Bring your questions and your medicine list to the blood bank, and accept its answer on the day.
Questions we are asked
Common questions about who can donate blood
What is the minimum weight to donate blood in India?
You need to weigh at least 45 kg to give the smaller bag of 350 millilitres. Many blood banks now collect the larger bag, which needs at least 55 kg. Staff will weigh you on the day.
How often can I donate whole blood?
Men wait at least ninety days between whole blood donations, and women wait at least one hundred and twenty days. Women wait longer because monthly periods mean their iron stores take more time to refill. Platelet donation follows a different schedule, which the blood bank will explain if you are asked to give platelets.
Can I donate if I have high blood pressure?
Often yes, if it is well controlled and your reading on the day is within the blood bank's limits. Keep taking your tablets as your doctor prescribed. If your reading is high that morning, you will be asked to come another day. Uncontrolled pressure, or heart disease linked to it, usually rules you out.
My haemoglobin was too low at the camp. Should I worry?
Not necessarily, but do not ignore it. A finger-prick test is quick and can read lower than a lab test, and ranges differ between laboratories. If it happens more than once, or you feel tired or breathless, see your doctor for a full blood count. Many people simply need their iron checked.
Can I donate if I had cancer years ago?
Under the national guidelines, a history of cancer usually rules out blood donation, even after treatment has finished. That includes leukaemia and lymphoma. It is meant to protect the person who receives your blood. You can still help by encouraging healthy family members and friends to register as donors.
Can I donate after a COVID vaccine or other vaccine?
Many vaccines need only a short wait, while some live vaccines need a longer one. The rules have changed over time, so tell the blood bank which vaccine you had and the date. They will tell you whether you can give blood that day or when to return.
Do I need to eat before donating?
Yes. Eat a normal meal a few hours before, and drink plenty of water. Do not donate on an empty stomach or after a night without sleep, because that is when people feel faint. Avoid alcohol the day before, and skip heavy exercise for the rest of the day after donating.
Will a blood bank pay me or give me a certificate?
No blood bank may pay you, because selling blood is illegal in India. Most voluntary donors receive a donor card and a certificate. Some blood banks give donor cards that help the donor or family get blood later, but those schemes vary, so ask what your card actually offers.
