How It Works
From a simple swab to a life-saving gift. Understanding the journey.
Why Ethnicity Matters
The donor's cells must match the patient's genetic markers (HLA type). This matching is heavily influenced by ancestry. If you're South Asian, your genetics are most likely to match another South Asian person.
With only 3% representation in the global registry, South Asian patients face daunting odds. Your registration changes those numbers.
Registration & Swab
Visit an official drive or register online with NMDP. We provide a simple medical history form and a painless cheek swab. This collects your HLA (human leukocyte antigen) markers to determine your genetic profile.
The Waiting Period
Your data is securely added to the national registry. You remain on the registry until age 61. Many people are never called, but your presence increases the odds for every South Asian patient in need of a match.
Potential Match
If a patient's doctor identifies you as a potential match, you'll be contacted for a follow-up health screening. This only confirms your initial markers are a likely match for the patient's urgent need.
Confirmatory Testing
You'll undergo further blood tests and a physical exam to ensure the donation is safe for both you and the patient. NMDP covers all medical costs associated with these tests.
The Donation
There are two methods: PBSC (80% of cases), which is a non-surgical blood draw similar to plasma donation, and Marrow Donation (20% of cases), a surgical procedure under anesthesia. Both are safe, life-saving acts.
Recovery & Follow-Up
Most PBSC donors return to normal activities within 1-2 days. Marrow donors may feel soreness for 1-2 weeks. NMDP follows up with you for at least a year to ensure your total health and well-being.
