Weight and BMI thresholds differ by registry and country, so no single number on this page would be accurate for everyone. The official registry serving your country applies its own current guidance to the health history you provide.

NMDP does not publish a minimum-weight table, but it says extremely low weight requires careful evaluation. NMDP also publishes its own maximum-weight chart.

Jada Bascom was diagnosed with acute myeloid leukemia at one month old and received her transplant at seven months old from Torsten Huber, a man who had registered with DKMS in Germany roughly five thousand miles away after reading a newspaper article. Like about 70% of patients who need a transplant, no one in Jada's family was a match. The donor who fits a given patient is often a stranger who simply decided to be in the pool — which is the entire reason not to remove yourself from it on an assumption.
