02How it works

We perfectly match studentswith patients who need them.

HemoLink is the connective tissue between King Abdulaziz University’s student body and the KAUH Blood Bank. Students register and get screened in person; coordinators verify the results and approve each match.
02How it works

Screened.Matched.Approved.

Students complete Blood Bank testing first. Coordinators verify every match before a pledge becomes active.

ABO & RhD,on a grid.

ABO/RhD compatibility is only the first filter. HemoLink also checks Blood Bank antigen results before a pledge can move forward.

Move over any square to see whether that donor and recipient pair is a preliminary ABO/RhD match.

04Patient privacy

Names go in.Codes come out.

Students never see patient identities. Coordinators enter the full record in the admin console; HemoLink generates a stable non-identifying code (HL-PT-XXXX) and exposes only what's needed to determine compatibility.

Names never reach students
They see a stable code like HL-PT-7F2A — never a name, ID, or phone.
02
Only what changes the match
Blood type, urgency, and units. Nothing else leaves the coordinator console.
03
Codes are non-reversible
You can't work backward from HL-PT-7F2A to a person.
04
Patient consent is on file
Every record entered is acknowledged by the patient or a guardian first.
