Need blood in Chennai? Check e-RaktKosh first

If someone in your family needs blood in Chennai, the quickest first check is the Union Health Ministry’s e-RaktKosh portal. It shows component-wise stock at registered blood centres, lists nearby blood banks and publishes upcoming donation camps, so you can see which hospital actually has O negative packed cells before you start making calls.

Donors use the same portal. You can look up camps, log in to see your own donation record and register a group of voluntary donors. Chief Minister C. Joseph Vijay marked National Voluntary Blood Donation Day on 1 October with an appeal to young people in particular to donate and take a pledge, while health officials held special camps across the state with hospitals, NGOs and colleges (The Hans India).

Finding blood: start with e-RaktKosh

The public side of e-RaktKosh has three tools that matter when you are searching for a patient:

Blood Availability Search: pick the state, district, blood group and component (whole blood, packed red cells, platelets, plasma) to see which centres report stock.
Blood Bank Directory: addresses and contact details of registered centres, filterable by district.
Thalassemia Request: a separate route for patients who need regular transfusions.

Stock figures are only as current as the last update from each centre, so treat the portal as a shortlist. Call the blood bank before you travel, and carry the doctor’s requisition form, the patient’s details and the blood group report. Most hospitals will also ask for a replacement donor from the family, even though the unit itself is issued from stock.

Platelets have the shortest shelf life of any component, so shortages show up first in dengue season.

Government blood banks in Chennai

The big teaching hospitals run their own blood centres. A Citizen Matters listing of government centres in the city included Rajiv Gandhi Government General Hospital near Central, Stanley in Royapuram, Kilpauk Medical College Hospital, Government Royapettah Hospital, the Institute of Obstetrics and Gynaecology and the Institute of Child Health at Egmore, Kasturba Gandhi Hospital in Triplicane, RSRM Hospital in Royapuram and the Government Peripheral Hospital at Anna Nagar. Phone numbers change, so take current contacts from the e-RaktKosh directory rather than old lists.

Statewide, the Health department’s 2024-25 policy note counts 98 blood banks and 279 blood storage centres, which together supplied 4.57 lakh units between April 2023 and March 2024. Storage facilities have also been set up in 377 upgraded primary health centres and 48 taluk and non-taluk hospitals, which helps with emergencies such as delivery complications outside the city.

That supply has had to recover. Tamil Nadu collected 3.43 lakh units in 2021, roughly 60 to 70% of pre-Covid levels, according to figures the Health Minister gave DT Next at the time.

Who can donate

Blood centres in India screen donors against national donor-selection guidelines issued in October 2017. State transfusion councils publish summaries of the basic checks. The Uttar Pradesh State Blood Transfusion Council lists these:

Check	Requirement
Age	18 to 65 years
Body weight	At least 45 kg
Haemoglobin	At least 12.5 g/dL
Pulse	50 to 100 a minute, regular
Blood pressure	Systolic 100 to 180, diastolic 50 to 100 mm Hg
Temperature	Not above 37.5°C
Gap between donations	About three months

Some councils use a lower upper age limit, so first-time donors over 60 should check with the centre. The Assam council’s list shows the kinds of things that lead to a temporary deferral: a recent tattoo, piercing or acupuncture, recent surgery or serious illness, a recent vaccination, antibiotics or other medicines, malaria treatment, alcohol in the previous day, or a cold or sore throat on the day. Women do not donate during pregnancy, breastfeeding or periods. The doctor at the blood centre makes the final call after the short health questionnaire and a haemoglobin test.

If you have diabetes, heart disease, high blood pressure or another long-term condition, ask your doctor and the blood centre before turning up. This article is not medical advice.

How to donate in Chennai

Pick a government blood centre or a camp listed on e-RaktKosh. Hospital centres usually take walk-in donors during working hours; call ahead.
Eat a normal meal, drink water and sleep well the night before. Carry photo ID.
Fill in the donor form honestly, including recent travel, medicines and tattoos. It protects the patient and you.
After a haemoglobin and blood pressure check, the donation itself takes about 10 minutes. Rest and have the refreshments offered before leaving.
Register on e-RaktKosh so your donations are recorded and camps can reach you.

Colleges, residents’ associations and offices can register a donation camp through the portal, in tie-up with a licensed blood centre.

Quick answers

Can I check blood stock in Chennai online?

Yes. Use Blood Availability Search on e-RaktKosh, choose Tamil Nadu and Chennai, and select the group and component. Confirm by phone before going.

How often can I donate whole blood?

State council guidance puts the gap at about three months for whole blood.

I got a tattoo recently. Can I donate?

Not straight away. Tattoos and piercings bring a deferral of several months; the blood centre will tell you when you can return.

Is blood free at government hospitals?

Blood is issued to patients in government hospitals, though families are often asked to arrange a replacement donor. Ask the hospital’s blood bank about its current practice.
