How Location-Based Blood Donor Matching Works

The right donor is usually the nearest compatible one.

Area, not address

Donors register an area and radius; requests carry a hospital location. Matching happens between the two without ever exposing a home address.

A 10 km donor isn't pinged for a hospital 200 km away — relevance is what keeps alert fatigue near zero.

The public map shows area-level donor density, telling communities exactly where founding donors are needed most.

Do you use GPS tracking?

No — location is the area you typed or picked, updated only by you.

What about patients in villages?

Requests pin the treating hospital; donors from the nearest towns within radius get alerted.
