Together for a Healthier Tomorrow
The Life Savers is a healthcare technology platform. It helps connect people who need blood with potential voluntary donors, and lets you book lab tests — with home sample collection where available — through labs on our network.
We are not a blood bank: we don't store or supply blood, and we can't guarantee a donor or a unit. In an emergency, contact the hospital or emergency services first.
Who we are
The Life Savers is a healthcare technology platform. It helps connect people who need blood with potential voluntary donors, and gives access to lab and blood testing through a network of labs across India. These are two separate services in one account.
If you or your family need blood, you can post a request and registered donors with a compatible blood group nearby who have marked themselves available are alerted. If you want to help, you can register as a potential voluntary donor.
Search blood tests, diagnostic tests and health packages, book online, choose home sample collection where a lab offers it, and follow your order to the report.
In an emergency. In a medical emergency, contact the hospital or emergency services first. Use The Life Savers alongside them — never instead of them.
Most people come to The Life Savers at a stressful moment. These are the concrete things it helps with — and, just as important, what it doesn't do.
Search registered donors by blood group and location and contact them directly. Donors are voluntary, and we can't guarantee that anyone will be available.

Three things people come here to do. Each one below is how the app works today — nothing more.
Ask registered donors near you for help — and keep working with the hospital's blood bank.
Step 1: Sign in and open Community
Choose ‘Need blood urgently?’. You need an account to post a request.
Step 2: Fill in the three-step request
Blood group and patient, hospital and location (including pincode), then a contact number and the time blood is needed by.
Step 3: Compatible donors are alerted
The request appears in Community chat, and registered donors with a compatible group who are marked available near you are alerted — by pincode first, then city, then district.
Step 4: Donors call you; you close the loop
Interested donors call the number on the request. Mark it fulfilled when you have the blood, or remove it.
We connect people; we are not a blood bank and can't promise a donor will be available. Blood is only issued by licensed blood centres, so also contact the hospital's blood bank.
Become discoverable when someone nearby needs your blood group — and keep a record of your donations.
Step 1: Create your donor profile
Add your blood group and location and choose whether you are available to help.
Step 2: Check you can donate
Read the India eligibility guide on this page. The blood centre's doctor makes the final decision on the day.
Step 3: Donate at a licensed blood centre
Donation happens at a licensed blood centre, hospital or camp — never privately arranged through an app.
Step 4: Add your donation proof
Upload proof of your donation. Once our team reviews and approves it, you get a certificate and your next eligible date.
Being registered doesn't oblige you to donate — you decide each time, and eligibility is always checked at the blood centre.
Compare tests and packages, book with a partner lab, and follow the order to the report.
Step 1: Find your test
Search for a test or package, or browse by health concern. Compare what each includes and its price.
Step 2: Choose a lab and add to cart
Enter your details and pincode. Choose home sample collection where the lab offers it; some offers are lab-visit only.
Step 3: Pay
Pay online at checkout or, where offered, when your sample is collected, then follow the order from your account.
Step 4: Get your report
When the order shows ‘Report ready’, open the report from your order history. Your doctor should interpret the results.
We don't diagnose or recommend tests. Ask your doctor which tests you need.
One Platform. Many Moments of Care.
The Life Savers is a Made in India digital healthcare platform for people who need help quickly and want the process to feel clear.
The Life Savers connects people who need blood with potential voluntary donors, and lets you book lab tests online, with home sample collection where a lab offers it. Blood donor connections and lab testing are two separate services in one account — and we are a technology platform, not a blood bank or a doctor.
Whether you are looking for a donor near you, booking a blood test at home, or finding out who can donate in India, we want the next step to feel calm, clear and honest.

Blood in numbers
Blood is needed after accidents, for surgery and cancer treatment, in complicated pregnancies, for anaemia, and for regular transfusions in conditions such as thalassaemia and sickle cell disease. It can only come from donors — it can't be manufactured. India's national guideline still describes the country as facing a shortage of safe blood, and asks for regular, voluntary, unpaid donors.[1]
National figures below — not The Life Savers' own data.
Every figure below has a named source and a year. Where sources differ or a number is an estimate, we say so.
≈0.0 million units
Estimated annual blood requirement in India
NBTC's estimate as printed in the 2025 national guideline (the DGHS website states 14.6 million). National requirement estimation was carried out in 2016–17, so treat this as approximate.
12.6 → 14.6 million
Reported blood collections in India, 2023 → 2024
Annual collections in units, as reported by authors from DGHS and WHO India. Collections and the requirement estimate come from different sources and years, so they can't simply be subtracted to give a shortage figure — blood is also needed in the right place, group and component, and platelets last only 5 days.

Blood donation · India
Clear, sourced answers for people in India who are thinking about donating — or about asking for blood. Follow your blood centre's advice if it differs.
These are the whole-blood criteria in India's national guideline. They are general guidance: the medical officer at the blood centre checks you on the day and makes the final decision.[1][6]
The blood centre decides. The blood centre's medical officer makes the final call. The guideline can also be updated, for example during outbreaks or when new vaccines are introduced, so check with your blood centre before you go.
These are India's rules. These rules are India's. Eligibility rules are set nationally and differ between countries — the WHO's donor-selection guidance is written to help each country build its own — so don't apply rules you have read about elsewhere.
Donating platelets or plasma by apheresis has its own rules — for example, donors are 18–60 years old and weigh at least 50 kg.
Being told to wait is common and usually temporary. These are examples of how long the national guideline asks people to wait — not a complete list, and not a way to check yourself. Always answer the blood centre's questions in full.[1]
Cold, flu, cough or sore throat
Usually wait: Until symptoms have gone and there is no fever
Fever with joint pain or a rash (cause not identified)
Usually wait: 28 days after symptoms settle
Antibiotics
Usually wait: 2 weeks after the last dose, if you are well
Tattoo, body piercing, acupuncture or a similar invasive cosmetic procedure
Usually wait: 12 months
Dental treatment
Usually wait: 48 hours after scaling or a filling · 14 days after a root canal or extraction · 12 months after a bone graft or reconstruction
Surgery
Usually wait: 3 months after minor surgery · 12 months after major surgery (counted from recovery)
Having received a blood transfusion
Usually wait: 12 months
Vaccination
Usually wait: 14 days after non-live vaccines (for example tetanus or injectable polio) · 28 days after live vaccines (for example oral polio, measles or yellow fever) · 1 year after anti-rabies vaccination following an animal bite
Malaria, typhoid, dengue or chikungunya
Usually wait: 3 months after recovery from malaria · 12 months for typhoid · 6 months for dengue or chikungunya
Pregnancy, childbirth, breastfeeding and menstruation
Usually wait: 12 months after delivery (including while breastfeeding within that time) · 6 months after an abortion · while menstruating
Some conditions rule out donation for good, and some long-term conditions do not automatically rule you out. Only the blood centre's medical officer can tell which applies to you.
Every donation is tested for five infections — HIV, hepatitis B, hepatitis C, syphilis and malaria — before it can be used. WHO recommends that all donations are screened for HIV, hepatitis B, hepatitis C and syphilis.[2][5]
Blood may only be collected by a licensed blood centre, by a qualified physician or a trained phlebotomist under a physician's supervision. India had 4,484 licensed blood centres in 2025.[1][3]
Voluntary, unpaid donors are considered the safest source of blood. Paid ‘professional’ blood donation has been banned in India since a 1996 Supreme Court judgment.[1][2]
Donation is a safe procedure, but some donors can have a reaction such as fainting. Blood-centre staff are trained to spot and manage this, and donor reactions are reported to India's national haemovigilance programme.[1]
A whole-blood donation is separated into components so each patient receives only what they need. The national guideline says one donation can benefit several patients (3–4).
Red cells
The part of blood matched to the patient's ABO and Rh blood group — see the compatibility chart below.[8]
Platelets
Help blood clot. Needed in dengue, malaria, aplastic anaemia, some blood cancers, chemotherapy, surgery and bleeding. Platelets last only 5 days at a blood centre, so they must be replaced constantly. They can also be donated by apheresis, which takes about 1 to 1.5 hours.[1]
Plasma
The liquid part of blood. Used, for example, when a patient lacks clotting factors. Stored frozen, it lasts up to a year.[1]
Myth: You should donate on an empty stomach.
Fact: Donors should not be fasting. The national guideline suggests your last meal is about 4 hours before donating.[1]
Myth: You can donate as often as you like.
Fact: There is a minimum gap between whole-blood donations: 3 months (90 days) for men and 4 months (120 days) for women.[1]
Myth: Paying donors is a normal way to get blood.
Fact: Paid ‘professional’ donation has been banned in India since 1996. Voluntary, unpaid donors are the safest source of blood.[1][2]
Myth: One blood group is the ‘best’ for every patient.
Fact: Compatibility depends on the component. Red cells and plasma are matched differently, and each transfusion must be matched to the patient.[8]
Myth: Women can't donate blood.
Fact: Women can donate if they meet the same criteria — age, weight of at least 45 kg and haemoglobin of at least 12.5 g/dL — with a longer minimum gap of 4 months, and with some temporary postponements around menstruation, pregnancy and childbirth.[1]
Myth: Anyone with a long-term condition can never donate.
Fact: Some conditions do rule out donation, but others do not automatically. For example, the guideline can accept people whose diabetes is well controlled by diet or oral medication, or whose blood pressure is within set limits with or without medication, provided there are no complications. The medical officer decides.[1]
Not sure whether you can donate? Ask the blood centre or camp doctor — they decide. For more, read the full guide or our blog.
This chart shows red-cell compatibility. It is for understanding only — the blood centre tests and cross-matches every unit, so never choose a donor for a patient on this chart alone.
| Blood group | Can donate red cells to | Can receive red cells from |
|---|---|---|
| A+ | A+AB+ | A+A-O+O- |
| O+ | O+A+B+AB+ | O+O- |
| B+ | B+AB+ | B+B-O+O- |
| AB+ | AB+ | Everyone |
| A- | A+A-AB+AB- | A-O- |
| O- | Everyone | O- |
| B- | B+B-AB+AB- | B-O- |
| AB- | AB+AB- | AB-A-B-O- |
Plasma follows different rules from red cells, and both blood and plasma transfusions must be matched to avoid a reaction.[8]
Browse by health concern
Start from what's on your mind. Each topic lists the tests doctors commonly use when looking into it, and the packages on our network that include them. It is a starting point for a conversation with a doctor — not a diagnosis.
These are general testing topics, not diagnoses. Talk to a doctor about your symptoms and about which tests, if any, are right for you.
Tap a test to see what it is, why a doctor may ask for it, how to prepare and where the information comes from. Home sample collection is available where the lab offers it.
Explanations are general information from the sources listed in each test. They aren't medical advice, and a test isn't necessary for everyone.
Three packages commonly offered at our partner centres, shown here exactly as listed in-store, ahead of the broader package families below.
A focused first checkup covering blood, organ function and thyroid.
9 tests
A commonly offered starter package, combining a blood count with liver, kidney, thyroid and cholesterol tests, plus calcium, iron studies and a fasting glucose and urine test.
A broader panel adding vitamins, uric acid and a full thyroid profile.
13 tests
A larger package building on the essential set with uric acid, vitamin D and vitamin B12, and a complete T3/T4/TSH thyroid profile, plus Transferrin as an iron-related test.
The fullest package, adding HbA1c, pancreatic enzymes and inflammation and joint markers.
17 tests
The most complete of the three, adding HbA1c (a 3-month average blood sugar marker), amylase and lipase (pancreatic enzymes), CRP (an inflammation marker) and RA Factor (a joint-health marker) to the advanced set.
Always confirm the exact tests included and current availability with your lab before booking — package contents can vary by centre.
Want a broader picture instead of one test? These are the kinds of packages currently offered by labs on our network. Each card explains what a type of package is meant to cover; the exact tests and price depend on the lab and your location.
We only list package types that labs on our network currently offer. Contents, prices and availability differ by lab and location — check the exact inclusions before you book.

These are educational groupings, not diagnoses. Which tests suit you is something to decide with a doctor.
Trust & transparency
Trust in a health service should rest on things you can verify. Here is what The Life Savers does today — and, just as important, what it doesn't.
A donation certificate is issued only after our team has reviewed the proof you upload. Your next eligible date is calculated from the approved donation.
Every blood request carries the hospital, location, contact number and needed-by time, and expires automatically. The requester can mark it fulfilled or remove it.
After you publish a request, the app tells you how many donors were alerted — including when nobody could be reached.
Lab bookings can be paid online or, where offered, on sample collection, and move through visible statuses — from placed to report ready — with the report kept in your order history.
Our privacy policy and terms are public, and you can request a callback or contact support before creating an account.

Short answers to the questions people ask us most. Health answers follow India's national guideline and name their sources; answers about the app describe how it works today.
Under India's national guideline, whole-blood donors are generally aged 18 to 65 (first-time donors up to 60), weigh at least 45 kg, have haemoglobin of at least 12.5 g/dL and are in good health on the day. The medical officer at the blood centre makes the final decision.[1]
For whole blood, the national guideline sets a minimum gap of 3 months (90 days) for men and 4 months (120 days) for women. Donating platelets or plasma by apheresis follows different, shorter limits set by the blood centre.[1]
You register, have a short talk about the process, answer a health questionnaire and are checked by a doctor — weight, pulse, blood pressure, temperature and haemoglobin. You then give written consent. Eat a normal meal beforehand; donors should not be fasting.[1]
Donation is a safe procedure when it is done at a licensed blood centre by trained staff. Some donors can feel faint or have a reaction, and staff are trained to manage this, so tell them straight away if you feel unwell. Every donation is also tested for HIV, hepatitis B and C, syphilis and malaria before it is used.[1][2]
You may feel the needle when it goes in, but the donation itself should not be painful. Tell the staff straight away if you feel pain, dizziness or unwell. The whole visit typically takes about an hour and the donation itself usually 5 to 10 minutes, according to NHS Blood and Transplant (UK).[7]
Drink plenty of fluids, avoid heavy work, and don't smoke or drive immediately afterwards. Remove the adhesive dressing after about 6 hours. If your job is hazardous, don't return to it for at least 24 hours. Contact the blood centre if you feel unwell.[1]
It depends on the medicine and the reason you take it. Under the national guideline, many common medicines such as vitamins and oral contraceptives are accepted, while antibiotics mean waiting 2 weeks after the last dose. Some medicines rule out donation, so tell the blood centre's doctor about everything you take — the decision is theirs.[1]
Usually you need to wait until you have fully recovered. For a cold or flu that means until symptoms have gone and there is no fever. After malaria the guideline asks for 3 months, after dengue or chikungunya 6 months, and after typhoid 12 months, each counted from full recovery. The blood centre will advise you.[1]
In India, the national guideline postpones donation for 12 months after a tattoo, body piercing, acupuncture or a similar invasive cosmetic procedure. Rules in other countries differ, so follow the Indian guideline and your blood centre.[1]
Yes, if they meet the same criteria — age 18 to 65, weight of at least 45 kg and haemoglobin of at least 12.5 g/dL — with a minimum gap of 4 months between whole-blood donations. Donation is postponed during menstruation, and for 12 months after childbirth or while breastfeeding within that time. It is postponed for 6 months after an abortion.[1]
For red cells, O-negative can be given to any group and AB-positive patients can receive from any group; the chart on this page shows every pairing. Plasma follows different rules, and the blood centre always tests and cross-matches each unit, so a chart is for understanding, not for choosing a donor.[8]
Whole blood is the usual donation of 350 ml or 450 ml, which is separated into components so it can help several patients. Platelets help blood clot and last only 5 days at a blood centre. Plasma is the liquid part of blood, stored frozen for up to a year. Platelets and plasma can also be donated by apheresis, which takes about 1 to 1.5 hours.[1]
Sign in, open Community and choose ‘Need blood urgently?’. A three-step form asks who needs blood, where, and how donors can reach you. When you publish, the request appears in Community chat and an alert goes to registered donors with a compatible blood group who have marked themselves available near you. We connect people — we are not a blood bank, and we can't guarantee that a donor is available. Also contact the hospital's blood bank, and use the government's e-RaktKosh portal to look up blood centres.[9]
Blood group, patient name, number of units (1 to 10), hospital, state, district, city and pincode, a contact number, and the time blood is needed by, which must be at least 15 minutes ahead. You can add notes such as a landmark or ward. A new request can be published once every 15 minutes.
Matching donors can receive a notification and open the request in Community, which shows the hospital, location and needed-by time with a button to call the requester. Donation itself happens at the hospital or a licensed blood centre after its eligibility check — never privately arranged. The requester marks the request fulfilled when it is done.[1]
We alert matching donors by pincode first, then by city, then by district, using the location each donor saved in their profile. If no compatible, available donor is registered nearby, nobody may be alerted — after you publish, the app tells you how many donors were reached, or that none were.
Search for a test or package, choose a lab, add it to your cart and enter your details, including the pincode. Where the lab offers home sample collection you can choose it — some offers are lab-visit only. You pay online and can follow the order from your account.
Start from your doctor's advice or prescription and compare what each package includes and its price. We don't diagnose or recommend tests, and a booking is not a substitute for a doctor's consultation — your doctor decides which tests you need.
Each test shows its usual report time. You can follow your order through Placed, Order accepted, Sample collected, In progress and Report ready. When it shows Report ready, open the report from your order history. Reports come from the partner lab; we don't interpret results, so please discuss them with your doctor.
Check that the lab serves your pincode, whether the offer is home collection or lab visit only, the total price, and any preparation instructions for the test — such as fasting — given by your doctor or the lab. Follow those instructions.
