Individuals can now join the register by simply providing a saliva sample and posting it off along with a questionnaire.
The Anthony Nolan Trust said it hopes the development will double the number of lives saved each day.
Potential donors do not now have to provide a sample of blood for medical staff to find out their tissue type.
The trust’s chief executive, Henny Braund, said: “We urgently need to increase the number of people on our register and saliva testing will help us do that much more quickly and effectively.”
Those wishing to register as a bone marrow donor must be aged 18-40, weigh more than eight stone (51kg) and have good general health.
