Why every donor matters

The need is real. The gap is deadly.
And it is fixable, by people like you.

~2 lakhbags of blood short in Bangladesh every year, need is nearly 10 lakh bags, only about 7.5 lakh are collected.
32%of Bangladesh's blood demand is met by voluntary donors. The rest depends on scrambling to find family and friends.
~70,000mothers die worldwide each year from bleeding after childbirth, largely preventable with timely blood.
61%of countries face blood shortages, with the biggest gaps across South Asia and sub-Saharan Africa.

What your gift can do

Fifteen minutes. Three lives.

Save up to 3 lives

A single donation is separated into red cells, plasma and platelets, helping three different patients.

Answer emergencies fast

Accident, surgery, childbirth, dengue, thalassemia and cancer patients often need blood within hours.

Give again safely

A healthy adult can donate every 3 to 4 months. Your body replaces the fluid within a day.

Help anywhere

Open to every country, state and city, matching is by your own city first, then wider.

Your privacy is protected

Your number stays yours until you say yes.

Your data stays private

Your details are never shown publicly and never sold. Health answers are seen only by our verified team, never by requesters.

Your number is shared only if you allow it

A donor or requester gets your mobile number only after you tap Accept, never before.

All alerts come through OBHIZATRIK Blood Network

Every SMS and notification is sent through the OBHIZATRIK Blood Network site, so your number is protected until you choose to share it.
