Why Donate Blood in Kolkata

Every unit donated in Kolkata stays in Kolkata. Local blood banks supply nearby hospitals, trauma centres, and dialysis wards — meaning your donation directly helps patients in your own community. Most blood banks in the area accept walk-in donors during working hours, the entire process takes under 30 minutes, and one donation can save up to three lives. If you're healthy and aged 18–65, you can donate every 90 days (males) or 120 days (females).
