How Transplants Work

HLA Typing

HLA (Human Leukocyte Antigen) is a subset of your DNA. In order to complete a successful transplant, donor and recipients have compatible HLA types. Pareto types all of its donors to ensure successful transplant. We determine your HLA type through your swab kit.

HLA Matching

HLA matching begins when a doctor initiates a search on Pareto's database for a patient in need. When a Pareto member matches, we schedule confirmatory testing to ensure donor comparability, health, and willingness to donate.


Once you match, Pareto will coordinate with the patient's doctor and a preferred apheresis center near you. For five days prior to donation, you will receive a medication called filgrastim to increase the number of stem cells in your bloodstream. 


When Pareto members donate to save a life, they get paid. Pareto compensates donors to enhance the lives of donors and patients. Get paid, be a hero!

Meeting Patients

Pareto requires that both donors and patients desire to be introduced. If both parties desire it, Pareto helps put together a special reunion a year after donation!

Second Donation

Some donors are fortunate enough to be able to provide two potentially life-saving treatments. Although this is rare, it can happen!


I've already been HLA typed through a bone marrow registry. Can I join Pareto?

Of course! Just request your HLA type from your current registry, and we'll get you registered with Pareto! Email to enroll!

I'm still confused what HLA typing is. Why can't I just donate now like with plasma or blood?

Your HLA type is sort of like your blood type, but much more complicated. Your HLA is the most complicated and evolving subset of your DNA, and it dictates the development and maintenance of your blood and circulatory system. As a result, matching takes a bit longer and you will have much fewer matches than with blood.

Where are you located?

We work with major medical centers all across the country!


Additional Questions

How do I actually donate the stem cells?

The process is a non-surgical procedure called apheresis. It's very similar to donating plasma, and takes about 3-4 hours. 

I'm interested in donating. How do I enroll?
